Amazon Linux 2 : gegl, --advisory ALAS2-2026-3183 (ALAS-2026-3183)

high Nessus Plugin ID 301266

Synopsis

The remote Amazon Linux 2 host is missing a security update.

Description

The version of gegl installed on the remote host is prior to 0.2.0-19. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2-2026-3183 advisory.

The `rgbe_read_new_rle` function in `gegl/libs/rgbe/rgbe.c` has a heap buffer overflow vulnerability during HDR image parsing that may allow remote code execution. (CVE-2026-2049)

When parsing an HDR image file, the function [rgbe_read_new_rle gegl/libs/rgbe/rgbe.c] contains HEAP Based Buffer Overflow vulnerability that can lead to remote code execution. (CVE-2026-2050)

Tenable has extracted the preceding description block directly from the tested product security advisory.

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

Solution

Run 'yum update gegl' or or 'yum update --advisory ALAS2-2026-3183' to update your system.
