Name of the Vulnerable Software and Affected Versions LibTIFF version 4.0.8

Description The issue is related to the TIFFReadDirEntryArray function in tif read.c, which mishandles memory allocation for short files. This can be exploited by remote attackers to cause a denial of service, leading to an allocation failure and application crash in the TIFFFetchStripThing function in tif dirread.c, particularly during a tiff2pdf invocation.

Recommendations For LibTIFF version 4.0.8, consider updating to a newer version that addresses this issue, as the current version mishandles memory allocation, leading to potential crashes. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
