Описание
libtiff up to v4.7.1 was discovered to contain a stack overflow via the readSeparateStripsIntoBuffer function.
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.
Меры по смягчению последствий
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.
