TITLE:
IrfanView PSD Image Parsing Two Vulnerabilities
SECUNIA ADVISORY ID:
SA39036
VERIFY ADVISORY:
http://secunia.com/advisories/39036/
DESCRIPTION:
Secunia Research has discovered two vulnerabilities in IrfanView,
which can be exploited by malicious people to compromise a user's
system.
1) A sign-extension error when parsing certain PSD images can be
exploited to cause a heap-based buffer overflow by tricking a user
into opening a specially crafted PSD file.
2) A boundary error when processing certain RLE compressed PSD images
can be exploited to cause a heap-based buffer overflow by tricking a
user into opening a specially crafted PSD file.
Successful exploitation of the vulnerabilities may allow execution of
arbitrary code.
The vulnerabilities are confirmed in version 4.25. Other versions may
also be affected.
SOLUTION:
Update to version 4.27.
PROVIDED AND/OR DISCOVERED BY:
Stefan Cornelius, Secunia Research.
