Technical description

SAIL is a cross-platform library for loading and saving images with support for animation, metadata, and ICC profiles. Prior to commit 45d48d1f2e8e0d73e80bc1fd5310cb57f4547302, the TGA codec's RLE decoder in `tga.c` has an asymmetric bounds check vulnerability. The run-packet path (line 297) correctly clamps the repeat count to the remaining buffer space, but the raw-packet path (line 305-311) has no equivalent bounds check. This allows writing up to 496 bytes of attacker-controlled data past the end of a heap buffer. Commit 45d48d1f2e8e0d73e80bc1fd5310cb57f4547302 patches the issue.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
