The AlmaLinux 9.6 host has packages installed that are affected by multiple vulnerabilities as referenced in the TuxCare ALMALINUX9.6:CLSA-2026:1785266060 advisory.

  - LIBPNG is a reference library for use in applications that read, create, and manipulate PNG (Portable     Network Graphics) raster image files. In versions 1.2.1 through 1.6.55, `png_set_tRNS` and `png_set_PLTE`     each alias a heap-allocated buffer between `png_struct` and `png_info`, sharing a single allocation across     two structs with independent lifetimes. The `trans_alpha` aliasing has been present since at least libpng     1.0, and the `palette` aliasing since at least 1.2.1. Both affect all prior release lines `png_set_tRNS`     sets `png_ptr->trans_alpha = info_ptr->trans_alpha` (256-byte buffer) and `png_set_PLTE` sets     `info_ptr->palette = png_ptr->palette` (768-byte buffer). In both cases, calling `png_free_data` (with     `PNG_FREE_TRNS` or `PNG_FREE_PLTE`) frees the buffer through `info_ptr` while the corresponding `png_ptr`     pointer remains dangling. Subsequent row-transform functions dereference and, in some code paths, write to     the freed memory. A second call to `png_set_tRNS` or `png_set_PLTE` has the same effect, because both     functions call `png_free_data` internally before reallocating the `info_ptr` buffer. Version 1.6.56 fixes     the issue. (CVE-2026-33416)

  - Little CMS (lcms2) through 2.18 has an integer overflow in CubeSize in cmslut.c because the overflow check     is performed after the multiplication. (CVE-2026-41254)

  - Vulnerability in Oracle Java SE (component: JSSE). Supported versions that are affected are Oracle Java     SE: 8u491, 8u491-perf, 11.0.31, 17.0.19, 21.0.11, 25.0.3, 26.0.1; Oracle GraalVM for JDK: 17.0.19 and     21.0.11; Oracle GraalVM Enterprise Edition: 21.3.18. Difficult to exploit vulnerability allows     unauthenticated attacker with network access via TLS to compromise Oracle Java SE. Successful attacks of     this vulnerability can result in unauthorized creation, deletion or modification access to critical data     or all Oracle Java SE accessible data. Note: This vulnerability can only be exploited by supplying data to     APIs in the specified Component without using Untrusted Java Web Start applications or Untrusted Java     applets, such as through a web service. (CVE-2026-46968)

  - Vulnerability in the Oracle Java SE, Oracle GraalVM for JDK, Oracle GraalVM Enterprise Edition product of     Oracle Java SE (component: ImageIO). Supported versions that are affected are Oracle Java SE: 8u491,     8u491-perf, 11.0.31, 17.0.19, 21.0.11, 25.0.3, 26.0.1; Oracle GraalVM for JDK: 17.0.19 and 21.0.11; Oracle     GraalVM Enterprise Edition: 21.3.18. Difficult to exploit vulnerability allows unauthenticated attacker     with network access via multiple protocols to compromise Oracle Java SE, Oracle GraalVM for JDK, Oracle     GraalVM Enterprise Edition. Successful attacks of this vulnerability can result in unauthorized update,     insert or delete access to some of Oracle Java SE, Oracle GraalVM for JDK, Oracle GraalVM Enterprise     Edition accessible data. 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. (CVE-2026-47010)

  - Vulnerability in the Oracle Java SE, Oracle GraalVM for JDK, Oracle GraalVM Enterprise Edition product of     Oracle Java SE (component: 2D).

Easily exploitable vulnerability allows unauthenticated attacker with     network access via multiple protocols to compromise Oracle Java SE, Oracle GraalVM for JDK, Oracle GraalVM     Enterprise Edition. Successful attacks of this vulnerability can result in unauthorized ability to cause a     partial denial of service (partial DOS) of Oracle Java SE, Oracle GraalVM for JDK, Oracle GraalVM     Enterprise Edition. 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.

The AlmaLinux 9.2 host has packages installed that are affected by multiple vulnerabilities as referenced in the TuxCare ALMALINUX9.2:CLSA-2026:1785332252 advisory.

  - LIBPNG is a reference library for use in applications that read, create, and manipulate PNG (Portable     Network Graphics) raster image files. Prior to 1.6.52, an out-of-bounds read vulnerability in libpng's     simplified API allows reading up to 1012 bytes beyond the png_sRGB_base[512] array when processing valid     palette PNG images with partial transparency and gamma correction. The PNG files that trigger this     vulnerability are valid per the PNG specification; the bug is in libpng's internal state management.
    Upgrade to libpng 1.6.52 or later. (CVE-2025-66293)

  - Vulnerability in the Oracle Java SE, Oracle GraalVM Enterprise Edition product of Oracle Java SE     (component: Hotspot). Supported versions that are affected are Oracle Java SE: 8u481 and 8u481-b50; Oracle     GraalVM Enterprise Edition: 21.3.17. Difficult to exploit vulnerability allows low privileged attacker     with logon to the infrastructure where Oracle Java SE, Oracle GraalVM Enterprise Edition executes to     compromise Oracle Java SE, Oracle GraalVM Enterprise Edition. Successful attacks require human interaction     from a person other than the attacker. Successful attacks of this vulnerability can result in unauthorized     creation, deletion or modification access to critical data or all Oracle Java SE, Oracle GraalVM     Enterprise Edition accessible data and unauthorized ability to cause a hang or frequently repeatable crash     (complete DOS) of Oracle Java SE, Oracle GraalVM Enterprise Edition. 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). (CVE-2026-22003)
