RHBA-2008:0732 - Bug Fix Advisory

Topic

Updated e2fsprogs packages that fix several bugs are now available.

Description

The e2fsprogs packages contain a number of utilities for creating,
checking, modifying, and correcting any inconsistencies in second and third
extended (ext2/ext3) file systems. These utilities include e2fsck, mke2fs,
debugfs, and tune2fs.

These updated packages fix the following bugs:

• e2fsck was unable to repair file systems with certain journal

corruptions. If an inode for a journal had a link count of 0, the journal
could still pass the "e2fsck" check; however, the kernel was unable to
mount such a file system, failing with an error such as "mount: wrong fs
type, bad option, bad superblock on /dev/[device]". In these updated
packages, if a journal has no links, checking is forced, which resolves
this issue.

• several defects discovered by the Coverity source code checker, that

could result in memory leaks, segmentation faults, or memory corruption,
have been resolved.

• headers in the "e2fsprogs-devel" package were not multilib aware, causing

problems when both the 32-bit and 64-bit versions of the "e2fsprogs-devel"
package were installed on bi-arch platforms.

• an aliasing violation, which could result in "dumpe2fs" causing a

segmentation fault on Itanium(R) architectures, has been resolved.

• in the previous e2fsprogs packages, an attempt to free an uninitialized

variable in "e2fsck", could have caused "e2fsck" to terminate when clearing
an extended attribute block. A "*** glibc detected *** free(): invalid
pointer" error may have occurred.

Users of e2fsprogs are advised to upgrade to these updated packages, which
resolve these issues.
