From security@slackware.com Fri Apr 26 04:31:59 2002 From: Slackware Security Team To: slackware-security@slackware.com Cc: bugtraq@securityfocus.com Date: Thu, 25 Apr 2002 14:10:26 -0700 (PDT) Subject: [slackware-security] sudo upgrade fixes a potential vulnerability 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.
