Rocky Linux 9.6 [TuxCare] Security Update: gimp / gimp-devel / gimp-devel-tools / gimp-libs Multiple Vulnerabilities (ALMALINUX9.6:CLSA-2026:1784108403)

high Nessus Plugin ID 352368

Synopsis

The Rocky Linux host is missing one or more security updates.

Description

The Rocky Linux 9.6 host has packages installed that are affected by multiple vulnerabilities as referenced in the TuxCare ALMALINUX9.6:CLSA-2026:1784108403 advisory.

- 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-2026-58380)

- A flaw was found in GIMP's PSD parser. An integer overflow in read_RLE_channel() can cause an undersized heap allocation for the RLE row-length table, after which subsequent per-row writes corrupt heap memory.
This could lead to memory corruption, potentially resulting in denial of service or arbitrary code execution. (CVE-2026-58384)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Update the affected packages based on the guidance in TuxCare advisory ALMALINUX9.6:CLSA-2026:1784108403.
