VetorAV:L/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H
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.
