- -------------------------------------------------------------------------

Package : gegl Version : 1:0.4.26-2+deb11u2 CVE ID : CVE-2026-2049 CVE-2026-2050

A heap-based buffer overflow was discovered in the RGBE/HDR parser of GEGL, a graph-based image processing library, which could result in denial of service or the execution of arbitrary code if malformed files are processed.

For Debian 11 bullseye, these problems have been fixed in version 1:0.4.26-2+deb11u2.

We recommend that you upgrade your gegl packages.

For the detailed security status of gegl please refer to its security tracker page at:
