Low [CVE-2026-16517] Signed Integer Overflow in archive_write_zip_header
A signed integer overflow vulnerability was found in libarchive's ZIP writer. In the archive_write_zip_header function in archive_write_set_format_zip.c, when ZIP encryption is enabled and the entry file size is close to INT64_MAX, the addition of the encryption overhead to the entry size overflows int64_t, resulting in undefined behavior. This could lead to incorrect Zip64 extension decisions or potential memory corruption. Red Hat Product Security rates this issue as Low severity. The vulnerability is in the ZIP write path only and requires both ZIP encryption to be enabled and a file size near INT64_MAX, making real-world exploitation highly unlikely. The resulting undefined behavior could theoretically cause incorrect Zip64 extension decisions or a crash, but the conditions are too contrived for practical exploitation. Weakness: CWE-190. 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 OpenShift Container Platform 4. Red Hat lists Red Hat Enterprise Linux 8; Red Hat Enterprise Linux 9 as not affected. Red Hat fixing advisory: RHSA-2026:69553, RHSA-2026:43818. Affected products named by the advisory: Red Hat package: libarchive.
Low [CVE-2026-47010] Enhance JPEG handling (Oracle CPU 2026-07)
Vulnerability in the Oracle Java SE, Oracle GraalVM for JDK, Oracle GraalVM Enterprise Edition product of Oracle Java SE (component: ImageIO). Note: This vulnerability can be exploited by using APIs in the specified Component, e.g., through a web service which supplies data to the APIs. This vulnerability also applies to Java deployments, typically in clients running sandboxed Java Web Start applications or sandboxed Java applets, that load and run untrusted code (e.g., code that comes from the internet) and rely on the Java sandbox for security. CVSS 3.1 Base Score 3.7 (Integrity impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:L/A:N). A flaw was found in OpenJDK. ASAN reports a heap integrity violation. 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-787. Affected products named by the advisory: OPENJDK ELS 11.0.32; Red Hat Build of OpenJDK 17.0.20; Red Hat Build of OpenJDK 21.0.12; Red Hat Build of OpenJDK 25.0.4; and 21 more.

Low [CVE-2026-47059] Enhance AWT ImagingLib (Oracle CPU 2026-07)
Vulnerability in the Oracle Java SE, Oracle GraalVM for JDK, Oracle GraalVM Enterprise Edition product of Oracle Java SE (component: 2D). Note: This vulnerability applies to Java deployments, typically in clients running sandboxed Java Web Start applications or sandboxed Java applets, that load and run untrusted code (e.g., code that comes from the internet) and rely on the Java sandbox for security. This vulnerability does not apply to Java deployments, typically in servers, that load and run only trusted code (e.g., code installed by an administrator). CVSS 3.1 Base Score 3.7 (Availability impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:L). A flaw was found in OpenJDK. When the software processes certain images, a specific function fails to manage memory boundaries correctly. This can lead to the application attempting to access invalid memory or dereference a null pointer, which may cause the application to unexpectedly terminate. The primary consequence of this vulnerability is a denial of service, making the affected application unavailable. Red Hat severity: Low — CVSS 3.7 (CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:L). Weakness: CWE-476. Affected products named by the advisory: OPENJDK ELS 11.0.32; Red Hat Build of OpenJDK 17.0.20; Red Hat Build of OpenJDK 21.0.12; Red Hat Build of OpenJDK 25.0.4; and 21 more.
Low [CVE-2026-12547] information disclosure in libsoup via soupauthmanager proxy credential leak on proxy switch
SoupAuthManager caches proxy authentication credentials without scoping them to the proxy authority (host:port). When the proxy configuration changes (e.g., via system settings or WPAD), cached Proxy-Authorization headers from the previous proxy are sent to the new proxy, leaking credentials. This vulnerability is deemed LOW because it requires the user changing the desktop proxy settings from an authenticated proxy to the attacker's proxy. Red Hat severity: Low — CVSS 3.4 (CVSS:3.1/AV:N/AC:L/PR:H/UI:R/S:C/C:L/I:N/A:N). Weakness: CWE-201. Affected Red Hat products: Red Hat Enterprise Linux 10. Red Hat does not currently list a fixing RHSA for this CVE. Affected products named by the advisory: Red Hat package: libsoup3.
Low [CVE-2026-59849] denial of service via automatic certificate authentication loop
A flaw was found in libssh.

Red Hat severity: Low — CVSS 3.1 (CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:N/I:N/A:L). Weakness: CWE-835. Affected Red Hat products: Red Hat Enterprise Linux 10; Red Hat Hardened Images. Red Hat lists Red Hat Enterprise Linux 8; Red Hat Enterprise Linux 9 as not affected. Red Hat fixing advisory: RHSA-2026:55855, RHSA-2026:42922. Affected products named by the advisory: Red Hat package: libssh.
Low [CVE-2026-59846] information disclosure via ProxyCommand %r username expansion
A flaw was found in libssh. A malicious username expanded through %r in ProxyCommand handling can inject shell metacharacters, exposing environment variables and causing unintended shell behavior. Red Hat severity: Low — CVSS 3.9 (CVSS:3.1/AV:L/AC:L/PR:L/UI:R/S:U/C:L/I:L/A:N). Weakness: CWE-78. Affected Red Hat products: Red Hat Enterprise Linux 10; Red Hat Enterprise Linux 8; Red Hat Enterprise Linux 9; Red Hat Hardened Images.
