Mandrake Linux Security Advisory : kdegraphics (MDKSA-2005:143)
Medium Nessus Plugin ID 19900
SynopsisThe remote Mandrake Linux host is missing one or more security updates.
DescriptionWouter Hanegraaff discovered that the TIFF library did not sufficiently validate the 'YCbCr subsampling' value in TIFF image headers. Decoding a malicious image with a zero value resulted in an arithmetic exception, which can cause a program that uses the TIFF library to crash.
Kdegraphics < 3.3 uses an embedded libtiff source tree for kfax, and as such has the same vulnerability.
The updated packages are patched to protect against this vulnerability.
SolutionUpdate the affected packages.
