CRITICAL:
Not critical

IMPACT:
DoS

Local system

SOFTWARE:
Exiv2 0.x

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.
