TITLE:
DevIL "iGetHdrHeader()" Buffer Overflow Vulnerabilities

SECUNIA ADVISORY ID:
SA33470

VERIFY ADVISORY:
http://secunia.com/advisories/33470/

CRITICAL:
Moderately critical

IMPACT:
System access

WHERE:
>From remote

SOFTWARE:
DevIL 1.x
http://secunia.com/advisories/product/20965/

DESCRIPTION:
Secunia Research has discovered two vulnerabilities in DevIL, which
can be exploited by malicious people to compromise an application
using the library.

The vulnerabilities are caused due to boundary errors within the
"iGetHdrHeader()" function in src-IL/src/il_hdr.c. These can be
exploited to cause a stack-based buffer overflow when processing
specially crafted Radiance RGBE files.

Successful exploitation allows the execution of arbitrary code.

The vulnerabilities are confirmed in version 1.7.4. Other versions
may also be affected.

SOLUTION:
Fixed in the SVN repository.

PROVIDED AND/OR DISCOVERED BY:
Stefan Cornelius, Secunia Research.
