| Vetor | AV: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 4.5.0
Description
The issue is caused by a buffer overflow on the stack in the uv encode() function of the LibTIFF library. This can occur when the library reads a corrupted little-endian TIFF file and specifies the output to be big-endian. Exploitation of this issue may allow an attacker to cause a denial of service.
Recommendations
For libtiff version 4.5.0, consider disabling the uv encode() function as a temporary workaround until a patch is available to prevent potential exploitation when reading corrupted little-endian TIFF files and specifying big-endian output.
