-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Mandrake Linux Security Update Advisory Package name: sudo Advisory ID: MDKSA-2002:028 Date: April 25th, 2002 Affected versions: 7.1, 7.2, 8.0, 8.1, 8.2, Corporate Server 1.0.1 Single Network Firewall 7.2 Problem Description: A problem was discovered by fc, with further research by Global InterSec, in the sudo program with the password prompt parameter (-p). Sudo can be tricked into allocating less memory than it should for the prompt and in certain conditions it is possible to exploit this flaw to corrupt the heap in such a way that could be used to execute arbitary commands. Because sudo is generally suid root, this can lead to an elevation of privilege for local users.

Slackware Affected

Updated:  April 26, 2002

Affected

Vendor Statement

New sudo packages are available to fix a security problem which may allow users to become root, or to execute arbitrary code as root. Here's the information from the Slackware 8.0 ChangeLog: Thu Apr 25 12:00:50 PDT 2002 patches/packages/sudo.tgz: Upgraded to sudo-1.6.6. This version of sudo fixes a security problem whereby a local user may gain root access through corruption of the heap (Off-By-Five). This issue was discovered by Global InterSec LLC, and more information may be found on their web site: http://www.globalintersec.com/adv/sudo-2002041701.txt The discussion on the site indicates that this problem may only be exploitable on systems that use PAM, which Slackware does not use. However, in the absence of proof, it still seems prudent to upgrade sudo immediately. (* Security fix *) WHERE TO FIND THE NEW PACKAGES: Updated sudo package for Slackware 7.1: ftp://ftp.slackware.com/pub/slackware/slackware-7.1/patches/packages/sudo.tgz Updated sudo package for Slackware 8.0: ftp://ftp.slackware.com/pub/slackware/slackware-8.0/patches/packages/sudo.tgz Updated sudo package for Slackware -current: ftp://ftp.slackware.com/pub/slackware/slackware-current/slackware/ap/sudo-1.6.6-i386-1.tgz MD5 SIGNATURE: Here is the md5sum for the package: Slackware 7.1: 1f2eb2c0e01c5d2182431cc401f78a89 sudo.tgz Slackware 8.0: d0598233fefeb9d37450eec10a087e07 sudo.tgz Slackware -current: 26c70a9a740823353300b23f110b3cca sudo-1.6.6-i386-1.tgz INSTALLATION INSTRUCTIONS: As root, upgrade to the new sudo.tgz package: # upgradepkg sudo.tgz Remember, it's also a good idea to backup configuration files before upgrading packages. - Slackware Linux Security Team http://www.slackware.com
