CVE-2022-36354
CVSS v3.1
5.3
Medium
| Vector | AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N |
Name of the Vulnerable Software and Affected Versions
OpenImageIO versions prior to v2.3.20
OpenImageIO master-branch-9aeece7a and v2.3.19.0
Description
A heap out-of-bounds read issue exists in the RLA format parser of OpenImageIO, specifically in the handling of run-length encoded byte spans. This can be triggered by a malformed RLA file, leading to an out-of-bounds read of heap metadata and potentially resulting in a sensitive information leak. An attacker can exploit this by providing a malicious file.
Recommendations
For OpenImageIO versions prior to v2.3.20, update to version v2.3.20 or later to resolve the issue.
For OpenImageIO master-branch-9aeece7a and v2.3.19.0, avoid using the RLA format parser until a patch is available.
As a temporary workaround, consider restricting access to the RLA file format to minimize the risk of exploitation.
