CVE-2025-61144

A denial of service flaw has been found in libtiff. This stack-based buffer overflow occurs in tiffcrop (part of libtiff) within the function readSeparateStripsIntoBuffer. When processing a malformed TIFF directory (e.g., improper tags/order, missing StripByteCounts), the function overflows a stack-allocated array (srcbuffs) by accessing one element beyond its boundary in combineSeparateSamplesBytes. This leads to an AddressSanitizer-detected buffer over-read and crash.

Red Hat employs StackGuard protections which limit the impact of this vulnerability to a denial of service. An out of bounds read in libtiff on a Red Hat system may cause a process termination, but does not pose further risk.

The CVSS score(s) listed for this vulnerability do not reflect the associated product's status, and are included for informational purposes to better understand the severity of this vulnerability.

Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base or stability.
