Gentoo Linux Security Advisory

Title: libextractor: Two heap-based buffer overflows (GLSA 200605-14)
Severity: normal
Exploitable: remote
Date: May 21, 2006
Bug(s): #133570
ID: 200605-14

Synopsis

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

Background

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

Affected Packages

Package: media-libs/libextractor
Vulnerable: < 0.5.14
Unaffected: >= 0.5.14
Architectures: All supported architectures


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:
