-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 - --------------------------------------------------------------------- Red Hat Security Advisory Synopsis: Updated ncompress package fixes security issue and bug. Advisory ID: RHSA-2004:536-01 Advisory URL: https://rhn.redhat.com/errata/RHSA-2004-536.html Issue date: 2004-12-13 Updated on: 2004-12-13 Product: Red Hat Enterprise Linux CVE Names: CAN-2001-1413 - --------------------------------------------------------------------- 1. Summary: An updated ncompress package that fixes a buffer overflow and problem in the handling of files larger than 2 GB is now available. 2. Relevant releases/architectures: Red Hat Enterprise Linux AS (Advanced Server) version 2.1 - i386, ia64 Red Hat Linux Advanced Workstation 2.1 - ia64 Red Hat Enterprise Linux ES version 2.1 - i386 Red Hat Enterprise Linux WS version 2.1 - i386 3. Problem description: The ncompress package contains the compress and uncompress file compression and decompression utilities, which are compatible with the original UNIX compress utility (.Z file extensions). A bug in the way ncompress handles long filenames has been discovered. ncompress versions 4.2.4 and earlier contain a stack based buffer overflow when handling very long filenames. It is possible that an attacker could execute arbitrary code on a victims machine by tricking the user into decompressing a carefully crafted filename. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2001-1413 to this issue. This updated ncompress package also fixes a problem in the handling of files larger than 2 GB. All users of ncompress should upgrade to this updated package, which contains fixes for these issues. 4.
