Name of the Vulnerable Software and Affected Versions
libtiff version 4.0.10
Description
The issue is related to a heap buffer overflow in the
TIFFmemcpy function in tif unix.c of the libtiff library. This allows an attacker to cause a denial-of-service through a crafted tiff file. The vulnerability is associated with writing beyond the buffer boundaries in memory, which can be exploited to disrupt service.Recommendations
For libtiff version 4.0.10, consider disabling the
TIFFmemcpy function as a temporary workaround until a patch is available. Restrict access to crafted tiff files to minimize the risk of exploitation.
At the moment, there is no information about a newer version that contains a fix for this vulnerability.Exploit
