CVE-2026-71219 1 Redhat 3 Enterprise Linux, Gfs2-utils, Rhel Els 2026-11-05 4.7 Medium
A stack overflow vulnerability was found in gfs2-utils. The hash table traversal code in metawalk.c uses alloca() with an exponentially-derived size from the untrusted on-disk di_depth field without bounds validation. A crafted GFS2 filesystem image with a large di_depth value causes stack exhaustion and a denial of service when processed by fsck.gfs2, gfs2_edit, or savemeta.
CVE-2026-71218 2 Iperf3 Project, Redhat 3 Iperf3, Enterprise Linux, Rhel Els 2026-11-05 5.3 Medium
A flaw was found in iperf3. A remote unauthenticated attacker can exploit a vulnerability in the `JSON_read()` function, which accepts a peer-controlled message length and allocates memory without an upper bound. This allows the attacker to trigger excessive memory consumption, leading to a Denial of Service (DoS) through memory exhaustion, severe slowdown, or termination of the iperf3 service.
CVE-2026-70368 2 Redhat, Stunnel 3 Enterprise Linux, Rhel Els, Stunnel 2026-11-05 6.5 Medium
A stack-based out-of-bounds read vulnerability exists in the "s_vlog" function of stunnel, when handling oversized log messages via "vsnprintf". A remote attacker with network access to a stunnel service can send protocol inputs that trigger a log message longer than 1024 bytes, leading to an out-of-bounds stack read and a potential crash. In certain corner cases, the same vulnerability could be used to replace a series of trailing "\n" characters with "\0".
CVE-2026-70367 2 Redhat, Stunnel 3 Enterprise Linux, Rhel Els, Stunnel 2026-11-05 5.4 Medium
A Server-Side Request Forgery (SSRF) bypass vulnerability exists in “stunnel” 5.79 and lower when configured in SOCKS proxy mode. This flaw allows a client to bypass intended localhost restrictions by using IPv4-mapped IPv6 addresses (e.g., “::ffff:127.0.0.1”) or unspecified addresses ("0.0.0.0", "::"), enabling access to loopback-only services on the "stunnel" host that should not be network-reachable.
CVE-2026-68742 3 Fedoraproject, Redhat, Sssd 6 Sssd, Enterprise Linux, Openshift and 3 more 2026-11-05 5.5 Medium
A flaw was found in SSSD. The sss_nss_protocol_parse_addr() function in the NSS responder does not validate the addrlen field against the remaining packet body size. A local attacker can exploit this via a crafted GETHOSTBYADDR request to the NSS responder socket, causing an out-of-bounds read and process crash, resulting in a denial of service.
CVE-2026-68743 3 Fedoraproject, Redhat, Sssd 6 Sssd, Enterprise Linux, Openshift and 3 more 2026-11-05 5.5 Medium
A flaw was found in SSSD. The extract_authtok_v1() function in the PAM responder does not validate the auth_token_length field against the remaining buffer size before processing. A local attacker can exploit this via a crafted protocol v1 request to the PAM responder socket, causing an out-of-bounds read and process crash, resulting in a denial of service.
CVE-2026-6862 2 Redhat, Ubuntu 6 Enterprise Linux, Hummingbird, Openshift and 3 more 2026-11-05 5.5 Medium
A flaw was found in libefiboot, a component of efivar. The device path node parser in libefiboot fails to validate that each node's Length field is at least 4 bytes, which is the minimum size for an EFI (Extensible Firmware Interface) device path node header. A local user could exploit this vulnerability by providing a specially crafted device path node. This can lead to infinite recursion, causing stack exhaustion and a process crash, resulting in a denial of service (DoS).
CVE-2026-6861 2 Gnu, Redhat 4 Emacs, Emacs, Enterprise Linux and 1 more 2026-11-05 6.1 Medium
A flaw was found in GNU Emacs. This vulnerability, a memory corruption issue, occurs when Emacs processes specially crafted SVG (Scalable Vector Graphics) CSS (Cascading Style Sheets) data. A local user could exploit this by convincing a victim to open a malicious SVG file, which may lead to a denial of service (DoS) or potentially information disclosure.
CVE-2026-6843 2 Gnu, Redhat 6 Nano, Enterprise Linux, Nano and 3 more 2026-11-05 5.5 Medium
A flaw was found in nano. A local user could exploit a format string vulnerability in the `statusline()` function. By creating a directory with a name containing `printf` specifiers, the application attempts to display this name, leading to a segmentation fault (SEGV). This results in a Denial of Service (DoS) for the `nano` application.
CVE-2026-73199 1 Redhat 2 Enterprise Linux, Rhel Els 2026-11-05 6.5 Medium
A flaw was found in the `ipa-enrollment` SLAPI plugin. A remote authenticated client can exploit a null pointer dereference vulnerability by sending a malformed Lightweight Directory Access Protocol (LDAP) extended operation. By omitting the request value for the `JOIN_OID` in the `ipa-enrollment` extended operation, an attacker can trigger a server crash, potentially causing a denial of service.
CVE-2026-72693 1 Redhat 6 Enterprise Linux, Hardened Images, Hummingbird and 3 more 2026-11-05 7.8 High
`openvt -u` is intended to identify the owner of the current VT and then execute `login` as that user from a privileged context. In the documented `kbrequest`/init usage, the ownership test in `authenticate_user()` relies on `stat("/proc/<pid>/fd/0")`. `stat()` on `/proc/<pid>/fd/0` follows the symlink to the underlying TTY device node. As a result, `buf.st_uid` reflects the owner of the TTY node rather than the owner of the process holding the file descriptor. If the TTY owner returns to `root` or the getty owner after logout while an unprivileged process still has `fd 0` attached to that TTY, the check can incorrectly treat that process as belonging to the privileged console owner. Once that check succeeds, the `-u` path executes a passwordless login as the selected user. In the documented `kbrequest`/init deployment using `openvt -us`, this can result in passwordless `login -f root` on the spawned VT. This report establishes that privilege escalation path for that documented deployment; it does not claim equivalent reachability for deployments that do not use `openvt -u` from a privileged `kbrequest`/init path.
CVE-2026-59089 3 Gimp, Gnome, Redhat 4 Gimp, Gimp, Enterprise Linux and 1 more 2026-11-05 5.5 Medium
A flaw was found in GIMP. The PlayStation TIM loader, responsible for handling PlayStation image files, incorrectly calculates the size of the Color Look-Up Table (CLUT) due to an integer overflow. This occurs when multiplying num_colors and num_cluts, both 16-bit unsigned short integers, resulting in a value exceeding the maximum integer limit. An attacker could exploit this by providing a specially crafted image file, leading to undefined behavior and causing the GIMP plug-in to abort, effectively resulting in a denial of service.
CVE-2026-59088 2 Gimp, Redhat 3 Gimp, Enterprise Linux, Rhel Els 2026-11-05 5.5 Medium
A flaw was found in GIMP. A signed integer overflow vulnerability exists in the `file-fli` plugin when processing FLI image files. This occurs due to an incorrect calculation during memory allocation for image buffers, where the multiplication of image width and height can exceed the maximum integer value. A remote attacker could exploit this by tricking a user into opening a specially crafted FLI file, leading to the application crashing and resulting in a denial of service.
CVE-2026-58381 2 Gimp, Redhat 3 Gimp, Enterprise Linux, Rhel Els 2026-11-05 6.1 Medium
A flaw was found in GIMP's PSP file format parser. A double-free condition occurs in the read_layer_block() function when processing a specially crafted PSP file. This could allow an attacker to cause memory corruption, potentially leading to denial of service or arbitrary code execution.
CVE-2026-58380 3 Gimp, Gnome, Redhat 6 Gimp, Gimp, Enterprise Linux and 3 more 2026-11-05 7.3 High
A flaw was found in GIMP's PNM file format parser. When parsing a specially crafted PNM file, the pnmscanner_gettoken() function writes a null terminator one byte past the end of a stack-allocated buffer due to an off-by-one error in the loop boundary check. This could lead to memory corruption, potentially resulting in denial of service or arbitrary code execution.
CVE-2026-58224 2 Redhat, Samba 6 Ceph Storage, Enterprise Linux, Openshift and 3 more 2026-11-05 6.5 Medium
A flaw was found in Samba's CTDB, the clustered database service used by Samba. Insufficient integrity validation of received CTDB protocol packets allows malformed packets containing invalid field lengths, improperly terminated strings, or inconsistent packet sizes to be processed without adequate bounds checking. A remote attacker with access to the CTDB private network may trigger a denial of service through process crashes or excessive memory consumption and, in limited cases, disclose adjacent memory contents.
CVE-2026-57966 2 Redhat, Spice-space 3 Enterprise Linux, Rhel Els, Spice-vdagent 2026-11-05 4.4 Medium
A path traversal vulnerability was found in spice-vdagent. This flaw allows a malicious or compromised SPICE host to write arbitrary files to any location on the guest operating system. This occurs because the filename provided by the SPICE host during file transfers is not properly sanitized before being used. An attacker could exploit this to write to sensitive locations with the privileges of the spice-vdagent process, typically the logged-in user. This issue requires the SPICE host to be untrusted or compromised for exploitation.
CVE-2026-57965 2 Redhat, Spice-space 3 Enterprise Linux, Rhel Els, Spice-vdagent 2026-11-05 5.1 Medium
A flaw was found in spice-vdagent. A malicious or compromised SPICE host can trigger an integer overflow by sending a specially crafted message. This vulnerability can lead to a heap buffer overflow, causing the spice-vdagent daemon to crash and resulting in a Denial of Service (DoS) for the virtual machine. This issue requires the SPICE host to be untrusted or compromised for exploitation.
CVE-2026-5704 2 Gnu, Redhat 7 Tar, Discovery, Enterprise Linux and 4 more 2026-11-05 5 Medium
A flaw was found in tar. A remote attacker could exploit this vulnerability by crafting a malicious archive, leading to hidden file injection with fully attacker-controlled content. This bypasses pre-extraction inspection mechanisms, potentially allowing an attacker to introduce malicious files onto a system without detection.
CVE-2026-66759 2 Gimp, Redhat 3 Gimp, Enterprise Linux, Rhel Els 2026-11-05 7.1 High
A flaw was found in the file-icns plugin in GIMP. When applying a decompressed mask during ICNS image processing, the plugin reads from the mask data buffer without verifying if the cursor exceeds the allocated resource size. If a crafted file contains a truncated mask resource, the icns_decompress function continues reading past the bounds of the buffer. This out-of-bounds read vulnerability results in information disclosure of heap contents, where memory contents are leaked as alpha channel pixel values, or a crash leading to a denial of service if unmapped memory is accessed.
