DESCRIPTION:
A vulnerability has been reported in LibTIFF, which can be exploited
by malicious people to compromise a user's system.
The vulnerability is caused due to an error in the "ppm2tiff" utility
(tools/ppm2tiff.c) when parsing images and can be exploited to cause a
buffer overflow via a specially crafted e.g. PPM image.
Successful exploitation may allow execution of arbitrary code, but
requires tricking a user into converting a malicious image.
The vulnerability is reported in version 4.0.3. Other versions may
also be affected.
SOLUTION:
Fixed in the source code repository.
