From security@LINUX-MANDRAKE.COM Tue Jan 30 11:36:51 2001 From: Linux Mandrake Security Team To: BUGTRAQ@SECURITYFOCUS.COM Date: Mon, 29 Jan 2001 10:39:15 -0700 Subject: [BUGTRAQ] MDKSA-2001:017 - bind update -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 ________________________________________________________________________ Linux-Mandrake Security Update Advisory ________________________________________________________________________ Package name: bind Date: January 29th, 2001 Advisory ID: MDKSA-2001:017 Affected versions: 6.0, 6.1, 7.0, 7.1, 7.2, Corporate Server 1.0.1 ________________________________________________________________________ Problem Description: Four problems exists in all versions of ISC BIND 4.9.x prior to 4.9.8 and 8.2.x prior to 8.2.3 (9.x is not affected). Version 8.2.x contains a buffer overflow in transaction signature (TSIG) handling code that can be exploited by an attacker to gain unauthorized privileged access to the system, allowing execution of arbitrary code. BIND 4 contains both a buffer overflow in the nslookupComplain() function, as well as an input validation error in the same function. These two flaws in BIND 4 can result in a Denial of Service or the execution of arbitrary code if successfully exploited. Finally, both BIND 4 and BIND 8 suffer from an information leak in the query processing code that allows a remote attacker to access the program stack, possibly exposing program and/or environment variables. This flaw is triggered by sending a specially formatted query to vulnerable BIND servers. Linux-Mandrake ships with ISC BIND 8 and is therefore vulnerable to the first and final vulnerabilities previously mentioned. The first vulnerability is limited because any access gained exploiting it will result in restricted access due to the named server running as the user and group named, not as root. It is highly recommended that all Linux-Mandrake users upgrade BIND immediately to the latest 8.2.3 version that fixes these vulnerabilities. For more information, please read the CERT Advisory (CA-2001-02) at: http://www.cert.org/advisories/CA-2001-02.html ________________________________________________________________________ Please verify the update prior to upgrading to ensure the integrity of the downloaded package. You can do this with the command: rpm --checksig package.rpm You can get the GPG public key of the Linux-Mandrake Security Team at http://www.linux-mandrake.com/en/security/RPM-GPG-KEYS If you use MandrakeUpdate, the verification of md5 checksum and GPG signature is performed automatically for you.

If you want to upgrade manually, download the updated package from one of our FTP server mirrors and upgrade with "rpm -Fvh *.rpm". You can download the updates directly from one of the mirror sites listed at: http://www.linux-mandrake.com/en/ftp.php3. Updated packages are available in the "updates/[ver]/RPMS/" directory. For example, if you are looking for an updated RPM package for Linux-Mandrake 7.2, look for it in "updates/7.2/RPMS/". Updated source RPMs are available as well, but you generally do not need to download them. Please be aware that sometimes it takes the mirrors a few hours to update.
