Detail
| A security vulnerability has been identified and fixed in login application from shadow-utils, which could allow local users in the utmp group to overwrite arbitrary files via a symlink attack on a temporary file referenced in a line (aka ut_line) field in a utmp entry (CVE-2008-5394). The updated packages have been patched to prevent this. Note: Mandriva Linux is using login application from util-linux-ng by default, and therefore is not affected by this issue on default configuration. |

| Title: | DSA-1709-1 shadow -- race condition | ||
| Description: | Paul Szabo discovered that login, the system login tool, did not correctly handle symlinks while setting up tty permissions. If a local attacker were able to gain control of the system utmp file, they could cause login to change the ownership and permissions on arbitrary files, leading to a root privilege escalation. For the stable distribution, this problem has been fixed in version 4.0.18.1-7+etch1. For the unstable distribution, this problem has been fixed in version 4.1.1-6. We recommend that you upgrade your shadow package. | ||
