Secunia

Secunia Research has discovered two vulnerabilities in imlib2, which can be exploited by malicious people to cause a DoS (Denial of Service) or compromise an application using the library.

1) A boundary error exists within the "load()" function in src/modules/loaders/loader_pnm.c when processing the header of a PNM image file. This can be exploited to cause a stack-based buffer overflow by e.g. tricking a user into opening a specially crafted PNM image in an application using the imlib2 library.

Successful exploitation allows execution of arbitrary code.

2) A boundary error exists within the "load()" function in src/modules/loader_xpm.c when processing an XPM image file. This can be exploited to cause a stack-based buffer overflow by e.g. tricking a user into opening a specially crafted XPM image in an application using the imlib2 library.

Successful exploitation may allow execution of arbitrary code.

The vulnerabilities are confirmed in version 1.4.0. Prior versions may also be affected.
