Some vulnerabilities have been reported in GIMP, which can be exploited by malicious people to compromise a user's system.
1) An error exists within the parsing of KiSS palette files and can be exploited to cause a heap-based buffer overflow via a specially crafted palette file.
2) An integer overflow error within the "ReadImage()" function (plug-ins/common/file-gif-load.c) when parsing the "height" and "len" properties of an image file can be exploited to cause a heap-based buffer overflow via a specially crafted GIF file.
These vulnerabilities are reported in all 2.8.x and prior versions.
3) An error in the X Window Dump (XWD) plug-in when processing the color masks can be exploited to cause a stack-based buffer overflow via a specially crafted XWD file.
This vulnerability is confirmed in version 2.8.2 running on Windows.
Successful exploitation of the vulnerabilities allows execution of arbitrary code.
