Detail
Problem Description: An updated libxml2 package that fixes multiple buffer overflows 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 Red Hat Enterprise Linux AS version 3 - i386, ia64, ppc, s390, s390x, x86_64 Red Hat Desktop version 3 - i386, x86_64 Red Hat Enterprise Linux ES version 3 - i386, ia64, x86_64 Red Hat Enterprise Linux WS version 3 - i386, ia64, x86_64 3. Problem description: libxml2 is a library for manipulating XML files. Multiple buffer overflow bugs have been found in libxml2 versions prior to 2.6.14. If an attacker can trick a user into passing a specially crafted FTP URL or FTP proxy URL to an application that uses the vulnerable functions of libxml2, it could be possible to execute arbitrary code. Additionally, if an attacker can return a specially crafted DNS request to libxml2, it could be possible to execute arbitrary code. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2004-0989 to this issue. All users are advised to upgrade to this updated package, which contains backported patches and is not vulnerable to these issues. 4. Solution: Before applying this update, make sure that all previously-released errata relevant to your system have been applied. Use Red Hat Network to download and update your packages. To launch the Red Hat Update Agent, use the following command: up2date For information on how to install packages manually, refer to the following Web page for the System Administration or Customization guide specific to your system: http://www.redhat.com/docs/manuals/enterprise/ 5. Bug IDs fixed (http://bugzilla.redhat.com/ for more info): 137264 - CAN-2004-0989 multiple buffer overflows |

11324 | libxml2 Proxy FTP URL Processing Overflow A remote overflow exists in libxml2. libxml2's nanoftp.c xmlNanoFTPScanProxy() function fails to perform boundary checking of user-supplied data that is copied into a finite stack buffer, which could potentially cause a stack-based overflow. Using a specially crafted URL, an attacker can cause a denial of service or execute arbitrary code resulting in a loss of integrity or availability. |
11180 | libxml2 DNS Reply Overflows Remote overflows exist in libxml2. libxml's nanoftp.c xmlNanoFTPConnect() and nanohttp.c xmlNanoHTTPConnectHost() functions fail to properly perform boundary checking of DNS replies, an issue that could potentially cause stack-based overflows. Using specially-crafted DNS replies, an attacker that has hijacked or is controlling a DNS server can cause a denial of service or execute arbitrary code, resulting in a loss of availability or integrity. |
11179 | libxml2 FTP URL Processing Overflow A remote overflow exists in libxml2. libxml2's nanoftp.c xmlNanoFTPScanURL() function fails to perform boundary checking of user-supplied data that is copied into a finite stack buffer, which could potentially cause a stack-based overflow. Using a specially crafted URL, an attacker can cause a denial of service or execute arbitrary code resulting in a loss of integrity or availability. |
