CVE-2009-0746
Published: 27 February 2009
The make_indexed_dir function in fs/ext4/namei.c in the Linux kernel 2.6.27 before 2.6.27.19 and 2.6.28 before 2.6.28.7 does not validate a certain rec_len field, which allows local users to cause a denial of service (OOPS) by attempting to mount a crafted ext4 filesystem.
From the Ubuntu Security Team
The ext4 filesystem did not correctly validate certain length fields. A local attacker could mount a malicious ext4 filesystem, causing a system crash, leading to a denial of service.
