CVE-2008-3528 Information

Description

The error-reporting functionality in (1) fs/ext2/dir.c (2) fs/ext3/dir.c and possibly (3) fs/ext4/dir.c in the Linux kernel 2.6.26.5 does not limit the number of printk console messages that report directory corruption which allows physically proximate attackers to cause a denial of service (temporary system hang) by mounting a filesystem that has corrupted dir-i_size and dir-i_blocks values and performing (a) read or (b) write operations. NOTE: there are limited scenarios in which this crosses privilege boundaries.
