RHBA-2011:0787 - squashfs-tools bug fix update

Synopsis

squashfs-tools bug fix update

Type/Severity

Bug Fix Advisory (none)

Topic

An updated squashfs-tools package that fixes two bugs is now available.

Description

Squashfs is a highly compressed read-only filesystem for Linux. This package contains the utilities for manipulating squashfs file systems.

  • A glibc update exposed a coding error in mksquashfs. This error resulted in dracut hanging while booting the Red Hat Enterprise Virtualization Hypervisor from PXE/CDROM/USB and an invalid LiveCD image being produced. The lines "memcpy(data_cache, data_cache + SQUASHFS_METADATA_SIZE," and "memcpy(directory_data_cache, directory_data_cache +" were changed respectively to "memmove(data_cache, data_cache + SQUASHFS_METADATA_SIZE," and "memmove(directory_data_cache, directory_data_cache +", thus a Red Hat Enterprise Virtualization Hypervisor boot from PXE/CDROM/USB now successfully completes without hanging during a boot. (BZ#676774)

  • An error in unsquashfs code caused it to abort with "FATAL ERROR aborting: failed to read fragment table" during attempts to read a v3 image. The line "return;"is changed to "return TRUE;", thus unsquashfs is now able to read v3 images. (BZ#655952)

Users are advised to upgrade to this updated squashfs-tools package which resolves these issues.
