Low [CVE-2026-56375] Magick.NET-Q8-AnyCPU: Magick.NET-Q8-OpenMP-arm64: Ma…
ImageMagick through 7.1.2-18 contains a memory leak vulnerability in the ASHLAR coder when an action fails. Attackers can trigger failed actions to exhaust memory resources and cause denial of service. A flaw was found in ImageMagick. An attacker can exploit this by triggering failed actions, leading to the exhaustion of memory resources. This can result in a denial of service (DoS), making the affected system or application unavailable to legitimate users. Red Hat Enterprise Linux ships ImageMagick in RHEL 6 ELS and RHEL 7 ELS. This flaw has been rated as having a Low security impact and is not currently planned to be addressed in future updates of those products. For additional information, refer to the Issue Severity Classification:. Red Hat severity: Low — CVSS 3.3 (CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:L). Weakness: CWE-770. Affected Red Hat products: Red Hat Enterprise Linux 6; Red Hat Enterprise Linux 7. Red Hat does not currently list a fixing RHSA for this CVE. Affected products named by the advisory: Red Hat package: imagemagick.
Low [CVE-2026-60082] Denial of Service via out-of-bounds read
DBI versions before 1.651 for Perl do not enforce statement handle consistency with the row. When the statement handle had no fields but the source row was non-empty, the internal row-buffer helper would read from a negative array index. This could be triggered by a caller supplying inconsistent metadata and rows to the prepare method. A flaw was found in perl-DBI, a database interface for Perl. This vulnerability arises when the DBI library processes inconsistent data, specifically when a statement handle lacks fields but is associated with a non-empty data row. This inconsistency can cause the internal row-buffer to attempt reading from an invalid memory location, an out-of-bounds read. Red Hat severity: Moderate — CVSS 3.3 (CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:L). Weakness: CWE-125. Affected Red Hat products: Red Hat Enterprise Linux 10; Red Hat Enterprise Linux 6; Red Hat Enterprise Linux 7; Red Hat Enterprise Linux 8; Red Hat Enterprise Linux 9. Will not fix / out of support: Red Hat Enterprise Linux 6; Red Hat Enterprise Linux 7. Red Hat does not currently list a fixing RHSA for this CVE. Affected products named by the advisory: Red Hat package: perl-dbi.
Low [CVE-2026-60081] DBI::ProfileData: Denial of Service due to unbounded path index
DBI::ProfileData versions before 1.651 for Perl do not limit the path index. The path index column of profile dump files is used to allocate an array of data for the parser. An unbounded value allows an attacker to specify a large index and consume available memory. This vulnerability allows an attacker to cause a Denial of Service (DoS) by providing a specially crafted input. The flaw exists because the software does not properly limit the path index when processing profile dump files, which can lead to excessive memory consumption. Red Hat severity: Moderate — CVSS 2.8 (CVSS:3.1/AV:L/AC:L/PR:L/UI:R/S:U/C:N/I:N/A:L). Weakness: CWE-770. Affected Red Hat products: Red Hat Enterprise Linux 10; Red Hat Enterprise Linux 6; Red Hat Enterprise Linux 7; Red Hat Enterprise Linux 8; Red Hat Enterprise Linux 9. Will not fix / out of support: Red Hat Enterprise Linux 6; Red Hat Enterprise Linux 7. Red Hat does not currently list a fixing RHSA for this CVE.

Low [CVE-2026-15028] heap overflow OOB read while parsing a tar archive contains a PAX extended header
A flaw was found in libarchive. This vulnerability allows a remote attacker to trigger a heap overflow by providing a specially crafted tar archive. The issue occurs during the parsing of a PAX extended header containing a malformed SUN.holesdata sparse-file attribute. Successful exploitation could lead to a denial of service, making the system unavailable, or potentially allow for arbitrary code execution, giving the attacker control over the affected system. Conditions for Exploitation: Successful exploitation requires user interaction or a specific application workflow. Impact Limitations: Although the heap overflow has the potential to allow for arbitrary code execution, achieving this reliably is typically complex and highly dependent on the memory layout and protections of the specific application utilizing the library. In most common scenarios, the malformed archive will simply cause the parsing application to crash, resulting in a localized Denial of Service (DoS) rather than a full system compromise. Red Hat severity: Moderate — CVSS 3.9 (CVSS:3.1/AV:L/AC:L/PR:L/UI:R/S:U/C:L/I:N/A:L). Weakness: CWE-805. Affected Red Hat products: Red Hat Enterprise Linux 10; Red Hat Hardened Images; Red Hat Enterprise Linux 6; Red Hat Enterprise Linux 7; Red Hat Enterprise Linux 9; Red Hat OpenShift Container Platform 4. Red Hat lists Red Hat Enterprise Linux 8 as not affected.
Low [CVE-2026-15041] Non-constant-time comparison in PBKDF2-SHA256 password verification
A flaw was found in 389 Directory Server. The PBKDF2-SHA256 password verification function uses standard memcmp() for comparing password hashes instead of a constant-time comparison function. A remote attacker could potentially use timing measurements of LDAP bind attempts to infer partial hash information, though practical exploitation is extremely difficult due to PBKDF2 computational overhead. Red Hat severity: Low — CVSS 3.7 (CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:L/I:N/A:N). Weakness: CWE-208.

Low [CVE-2026-14935] webrtcbin accepts remote SDP without a=fingerprint due to inverted presence check
A logic vulnerability was found in GStreamer's webrtcbin component. The _check_sdp_crypto() function contains an inverted boolean condition that causes it to accept remote SDP offers or answers that lack the required a=fingerprint attribute, while incorrectly rejecting those that include it. An attacker with the ability to intercept and modify WebRTC signaling messages could exploit this to bypass the SDP-level DTLS certificate fingerprint binding, weakening defenses against man-in-the-middle attacks on media streams. This vulnerability is rated as Low severity because exploitation requires man-in-the-middle access to the WebRTC signaling channel, which is typically TLS-protected. Additionally, the DTLS layer may still independently validate certificates, limiting the practical impact of this bypass. The webrtcbin component is shipped as part of gstreamer1-plugins-bad-free in Red Hat Enterprise Linux 8, 9, 10, and RHIVOS. The vulnerability weakens one layer of defense-in-depth but does not constitute a complete cryptographic break. Red Hat severity: Low — CVSS 3.7 (CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:L/A:N). Weakness: CWE-670. Affected Red Hat products: Red Hat Enterprise Linux 10; Red Hat Enterprise Linux 6; Red Hat Enterprise Linux 7; Red Hat Enterprise Linux 8; Red Hat Enterprise Linux 9. Red Hat does not currently list a fixing RHSA for this CVE.

Low [CVE-2026-54786] Leak in WASIp1 `fd_renumber` implementation
Wasmtime is a runtime for WebAssembly. All versions prior to 24.0.10; versions 25.0.0 through those before 36.0.11; versions 37.0.0 through those before 44.0.3; and versions 45.0.0 and 45.0.1 contain a native implementation of WASIp1 which suffers from a leak in the fd_renumber function where the file descriptor being renumbered to is not properly closed. Wasmtime's implementation erroneously only updated the table of descriptors for WASIp1 and didn't update the underlying table of descriptors used by the host. This behavior means that while fd_renumber works correctly from a guest's perspective it ends up leaking resources in the host that aren't cleaned up until the corresponding Store is destroyed. In a loop, guests can use fd_renumber to cause hosts to exhaust both resources and file descriptors. This bug only affects the native implementation of WASIp1, meaning that only runtimes which load core wasm modules and expose fd_renumber are affected. Runtimes are additionally only affected if they expose the ability to acquire a file descriptor, such as opening a file. For runtimes that deny access to files they are unaffected. This issue has been fixed in versions 24.0.10, 36.0.11, 44.0.3, and 45.0.2. Its native implementation of WASIp1, a system interface for WebAssembly, contains a resource leak in the fd_renumber function.
Low [CVE-2026-56377] ImageMagick - Policy Bypass via Incorrect Path Validation
ImageMagick before 7.1.2-24 contains an incorrect policy check that allows attackers to create or truncate files disallowed by security policies. Remote attackers can bypass path policy restrictions in sandboxed conversion services to write arbitrary files outside intended boundaries. By circumventing these controls, an attacker can create or truncate files outside permitted security boundaries, leading to unauthorized file manipulation. This could lead to the creation or truncation of files outside of intended boundaries, potentially affecting data integrity in specific configurations where ImageMagick processes untrusted input in a sandboxed environment. Red Hat severity: Low — CVSS 3.3 (CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:N). Weakness: CWE-22. Affected Red Hat products: Red Hat Enterprise Linux 6; Red Hat Enterprise Linux 7. Will not fix / out of support: Red Hat Enterprise Linux 6; Red Hat Enterprise Linux 7. Red Hat does not currently list a fixing RHSA for this CVE. Affected products named by the advisory: Red Hat package: imagemagick.
