Name of the Vulnerable Software and Affected Versions
LibTIFF version 4.0.9
Description
The issue is related to a NULL pointer dereference in the
TIFFmemcmp function, which can be triggered by a crafted tiff file, allowing an attacker to cause a denial-of-service. This can be exploited through the tiffcp executable. The vulnerability is also described as a buffer overflow in memory, which can lead to a denial-of-service when a specially crafted tiff file is used.Recommendations
For LibTIFF version 4.0.9, consider avoiding the use of the
tiffcp executable with untrusted tiff files until a patch is available. As a temporary workaround, restrict the handling of tiff files to trusted sources 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
