Description:
Some vulnerabilities have been reported in Gimp, which can be exploited by malicious people to compromise a user's system.
1) An integer overflow exists within the function "seek_to_and_unpack_pixeldata()" in plug-ins/common/psd.c. This can be exploited to cause a heap-based buffer overflow by tricking a user into opening a specially crafted PSD file with large width or height values.
2) Multiple integer overflows exist within the DICOM, PNM, PSD, PSP, Sun RAS, XBM, and XWD loader plugins. These can potentially be exploited to cause a heap-based buffer overflow by tricking a user into opening specially crafted image files.
Successful exploitation may allow execution of arbitrary code.
Vulnerability #1 is confirmed and vulnerability #2 is reported in version 2.2.15. Other versions may also be affected.
Note: Additionally, Victor Stinner has reported multiple crashes and problems within the BMP, PCX, PSD, and PSP loader plugins, of which some may have a security impact.
Solution:
Update to version 2.2.17.

1) Stefan Cornelius, Secunia Research.
