Candidate: CVE-2009-0748
PublicDate: 2009-02-27
References:
https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2009-0748
http://www.ubuntu.com/usn/usn-751-1
Description:
The ext4_fill_super function in fs/ext4/super.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 the
superblock configuration, which allows local users to cause a denial of
service (NULL pointer dereference and OOPS) by attempting to mount a
crafted ext4 filesystem.
Ubuntu-Description:
The ext4 filesystem did not correctly validate certain superblock fields. A
local attacker could mount a malicious ext4 filesystem, causing a system
crash, leading to a denial of service.
