|Gentoo Linux Security Advisory
Title: libextractor: Two heap-based buffer overflows (GLSA 200605-14)
Date: May 21, 2006
libextractor is vulnerable to two heap overflow vulnerabilities which could lead to the execution of arbitrary code.
libextractor is a library used to extract metadata from arbitrary files.
Vulnerable: < 0.5.14
Unaffected: >= 0.5.14
Architectures: All supported architectures
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.
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.
There is no known workaround at this time.
All libextractor users should upgrade to the latest version:
|# emerge --sync
# emerge --ask --oneshot --verbose ">=media-libs/libextractor-0.5.14"
