Severity: Normal Title: libarchive (formerly named as bsdtar): Multiple pax Extension Header Vulnerabilities Date: August 08, 2007 Bugs: #184984 ID: 200708-03

Synopsis ========
Multiple vulnerabilities were found in libarchive (formerly named as app-archive/bsdtar), possibly allowing for the execution of arbitrary code or a Denial of Service.
Background ==========
libarchive is a library for manipulating different streaming archive formats, including certain tar variants, several cpio formats, and both BSD and GNU ar variants.
Affected packages =================
------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 app-arch/libarchive < 2.2.4 >= 2.2.4
Description ===========
CPNI, CERT-FI, Tim Kientzle, and Colin Percival reported a buffer overflow (CVE-2007-3641), an infinite loop (CVE-2007-3644), and a NULL pointer dereference (CVE-2007-3645) within the processing of archives having corrupted PaX extension headers.
Impact ======
An attacker can trick a user or automated system to process an archive with malformed PaX extension headers into execute arbitrary code, crash an application using the library, or cause a high CPU load.
Workaround ==========
There is no known workaround at this time.
Resolution ==========
All libarchive or bsdtar users should upgrade to the latest libarchive version:
# emerge --sync # emerge --ask --oneshot --verbose ">=app-arch/libarchive-2.2.4"
