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.
