Detail

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.

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"

Title: DSA-1455 libarchive1 -- denial of service
Description: Several local/remote vulnerabilities have been discovered in libarchive1, a single library to read/write tar, cpio, pax, zip, iso9660 archives. The Common Vulnerabilities and Exposures project identifies the following problems: It was discovered that libarchive1 would miscompute the length of a buffer resulting in a buffer overflow if yet another type of corruption occurred in a pax extension header. It was discovered that if an archive prematurely ended within a pax extension header the libarchive1 library could enter an infinite loop. If an archive prematurely ended within a tar header, immediately following a pax extension header, libarchive1 could dereference a NULL pointer. The old stable distribution (sarge), does not contain this package.
