Linux 2.4 / 2.6 Privilege Escalation / Denial Of Service

Posted Feb 23, 2011

Site pre-cert.de

PRE-CERT Security Advisory - Both the 2.4 and 2.6 Linux kernels have multiple vulnerabilities. A buffer overflow bug in mac_partition in fs/partitions/mac.c (for MAC partition tables) allows for a denial-of-service (kernel panic) condition via a corrupted MAC partition table. A division-by-zero bug in ldm_get_vblks in fs/partitions/ldm.c (for LDM partition tables) allows a denial-of-service (kernel oops) condition via a corrupted LDM partition table. A buffer overflow bug in ldm_frag_add in fs/partitions/ldm.c (for LDM partition tables) may allow escalation of privileges or disclosure of sensitive information via a corrupted LDM partition table.
