From security@slackware.com Mon Oct 27 17:30:17 2003 From: Slackware Security Team To: slackware-security@slackware.com Date: Mon, 27 Oct 2003 12:07:30 -0800 (PST) Subject: [slackware-security] gdm security update (SSA:2003-300-01) -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 [slackware-security] gdm security update (SSA:2003-300-01) GDM is the GNOME Display Manager, and is commonly used to provide a graphical login for local users. Upgraded gdm packages are available for Slackware 9.0, 9.1, and -current. These fix two vulnerabilities which could allow a local user to crash or freeze gdm, preventing access to the machine until a reboot. Sites using gdm should upgrade, especially sites such as computer labs that use gdm to provide public or semi-public access. More details about these issues may be found in the Common Vulnerabilities and Exposures (CVE) database: http://cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2003-0793 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2003-0794 Here are the details from the Slackware 9.1 ChangeLog: +--------------------------+ Wed Oct 22 12:10:11 PDT 2003 patches/packages/gdm-2.4.4.5-i486-1.tgz: Upgraded to gdm-2.4.4.5.
