CVE-2009-0745
Published: 27 February 2009
The ext4_group_add function in fs/ext4/resize.c in the Linux kernel 2.6.27 before 2.6.27.19 and 2.6.28 before 2.6.28.7 does not properly initialize the group descriptor during a resize (aka resize2fs) operation, which might allow local users to cause a denial of service (OOPS) by arranging for crafted values to be present in available memory.
From the Ubuntu Security Team
The ext4 filesystem did not correctly clear group descriptors when resizing. A local attacker could exploit this to crash the system, leading to a denial of service.
