http://secunia.com/advisories/18619/
CRITICAL:
Not critical
IMPACT:
DoS
WHERE:
Local system
SOFTWARE:
Exiv2 0.x
http://secunia.com/product/7039/
DESCRIPTION:
A vulnerability has been reported in Exiv2, which potentially can be
exploited by malicious people to crash certain applications on a
user's system.
The vulnerability is caused due to the use of the "sscanf()" function
on input file data that is not NULL terminated. This can cause
out-of-bounds memory access and may be exploited to crash an
application linked against the Exiv2 library when a image containing
specially-crafted IPTC metadata is processed.
The vulnerability has been reported in version 0.8. Prior versions
may also be affected.
SOLUTION:
Update to version 0.9.
