| Vetor | AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H |
Name of the Vulnerable Software and Affected Versions:
LibTIFF version 4.0.9
Description:
The issue is related to an uncontrolled resource consumption in the
TIFFSetDirectory function of tif dir.c. This can be exploited by remote attackers to cause a denial of service (DoS) via a crafted tif file. The problem occurs because the declared number of directory entries is not validated against the actual number of directory entries.Recommendations:
For LibTIFF version 4.0.9, consider disabling the
TIFFSetDirectory function as a temporary workaround until a patch is available. Restrict access to manipulated tif 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
