Package : libexif
Vulnerability : buffer overflow
Problem-Type : remote
Debian-specific: no
CVE ID : CAN-2005-0664
Debian Bug : 298464

Sylvain Defresne discovered a buffer overflow in libexif, a library that parses EXIF files (such as JPEG files with extra tags). This bug could be exploited to crash the application and maybe to execute arbitrary code as well.

For the stable distribution (woody) this problem has been fixed in version 0.5.0-1woody1.

For the unstable distribution (sid) this problem has been fixed in version 0.6.9-5.

We recommend that you upgrade your libexif package.
