Description Andrej Nemec 2017-01-25 12:56:31 UTC 
An out of boundary write has been found in libXpm which can be exploited by an attacker through maliciously crafted XPM files.

The affected code is prone to two 32 bit integer overflows while parsing extensions: the amount of extensions and their concatenated length.
