CRITICAL:
Moderately critical

IMPACT:
System access

WHERE:
>From remote

SOFTWARE:
libextractor 0.x

DESCRIPTION:
Luigi Auriemma has reported two vulnerabilities in libextractor,
which can be exploited by malicious people to cause a DoS (Denial of
Service) and potentially compromise an application that uses the
library.

1) A boundary error exists in the "asf_read_header()" function within
the asfextractor plugin when reading input from an ASF file. This can
be exploited to cause a heap-based buffer overflow via a specially
crafted ASF file with an overly large "total_size" value.

2) A boundary error exists in the "parse_trak_atom()" function within
the qtextractor plugin when reading input from a QT/MOV file. This can
be exploited to cause a heap-based buffer overflow via a specially
crafted QT/MOV file.

The vulnerabilities have been reported in version 0.5.13. Prior
versions may also be affected.

SOLUTION:
Update to version 0.5.14.
