libextractor: Two heap-based buffer overflows — GLSA 200605-14

libextractor is vulnerable to two heap overflow vulnerabilities which could lead to the execution of arbitrary code.

Affected Packages

media-libs/libextractor on all architectures
Affected versions < 0.5.14
Unaffected versions >= 0.5.14

Background

libextractor is a library used to extract metadata from arbitrary files.

Description

Luigi Auriemma has found two heap-based buffer overflows in libextractor 0.5.13 and earlier: one of them occurs in the asf_read_header function in the ASF plugin, and the other occurs in the parse_trak_atom function in the Qt plugin.

Impact

By enticing a user to open a malformed file using an application that employs libextractor and its ASF or Qt plugins, an attacker could execute arbitrary code in the context of the application running the affected library.

Workaround

There is no known workaround at this time.

Resolution

All libextractor users should upgrade to the latest version:

 # emerge --sync
 # emerge --ask --oneshot --verbose ">=media-libs/libextractor-0.5.14"
