TITLE:
imlib2 PNM and XPM Buffer Overflow Vulnerabilities

SECUNIA ADVISORY ID:
SA30401

VERIFY ADVISORY:
http://secunia.com/advisories/30401/

CRITICAL:
Highly critical

IMPACT:
DoS, System access

WHERE:
>From remote

SOFTWARE:
imlib2 1.x
http://secunia.com/product/3880/

DESCRIPTION:
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. Other versions
may also be affected.

SOLUTION:
Fixed in the CVS repository.
