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

Name of the Vulnerable Software and Affected Versions LibTIFF versions 3.9.3 through 4.0.9

Description The issue is related to the JBIGDecode function in the LibTIFF library, which decodes arbitrarily-sized JBIG into a buffer, ignoring the buffer size. This leads to an out-of-bounds write in the tif jbig.c JBIGDecode function. The exploitation of this issue may allow an attacker to cause a denial of service or execute arbitrary code using specially crafted image files.

Recommendations For LibTIFF versions 3.9.3 through 4.0.9, consider disabling the JBIG functionality until a patch is available. As a temporary workaround, restrict the use of the JBIGDecode function in the tif jbig.c file to minimize the risk of exploitation. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
