-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 ____________________________________________________________________________ Publisher Name: OpenPKG GmbH Publisher Home: Advisory Id (public): OpenPKG-SA-2007.002 Advisory Type: OpenPKG Security Advisory (SA) Advisory Directory: Advisory Document: Advisory Published: 2007-01-05 21:58 UTC Issue Id (internal): OpenPKG-SI-20070105.01 Issue First Created: 2007-01-05 Issue Last Modified: 2007-01-05 Issue Revision: 04 ____________________________________________________________________________ Subject Name: bzip2 Subject Summary: Compression Tool Subject Home: Subject Versions: * <= 1.0.3 Vulnerability Id: CVE-2005-0953, CVE-2005-0758 Vulnerability Scope: global (not OpenPKG specific) Attack Feasibility: run-time Attack Vector: local system Attack Impact: manipulation of data, arbitrary code execution Description: Together with two portability and stability issues, two older security issues were fixed in the compression tool BZip2 [0], versions up to and including 1.0.3. The first issue is a race condition which allows local users to modify permissions of arbitrary files via a hard link attack on a file while it is being decompressed, whose permissions are changed by bzip2 after the decompression is complete. The second issue affects the script bzgrep(1). It does not properly sanitize arguments, which allows local users to execute arbitrary commands via filenames that are injected into a sed(1) script.
