Description:
Some vulnerabilities have been reported in GTK+, which can be exploited by malicious people to cause a DoS (Denial of Service) and potentially to compromise a user's system.
1) An integer overflow error exists in "/gtk+/gdk-pixbuf/io-xpm.c" due to the insufficient validation of the "n_col" value before using it to allocate memory. This can cause a heap-based buffer overflow and may be exploited to execute arbitrary code when a specially crafted XPM file is opened in an application that is linked with the library.
This may be related to vulnerability #2 in:
SA12542
2) An error in "/gtk+/gdk-pixbuf/io-xpm.c" can cause an infinite loop when processing a XPM file with a large number of colours. This can be exploited to cause an application linked with the library to stop responding when a malicious XPM file is opened.
3) An integer overflow error exists in "/gtk+/gdk-pixbuf/io-xpm.c" when performing calculations using the height, width and colours of a XPM file. This may be exploited to execute arbitrary code or to crash an application that is linked with the library when a malicious XPM file is opened.
