RHBA-2012:0043 - ncompress bug fix update


Synopsis

ncompress bug fix update

Type/Severity

Bug Fix Advisory

Topic

An updated ncompress package that fixes one bug is now available for Red Hat Enterprise Linux 6.

Description

The ncompress package contains the compress and uncompress file compression and decompression utilities, which are compatible with the original UNIX compress utility (.Z file extensions).

This update fixes the following bug:

  • The ncompress utility previously relied on the glibc implementation of the memcpy() function. A recent glibc update optimized memcpy(), which resulted in data corruption in ncompress file compression and decompression. This update replaces memcpy() with the memmove() function and ncompress now works as expected. (BZ#781973)

All users of ncompress are advised to upgrade to this updated package, which fixes this bug.

Solution

Before applying this update, make sure all previously released errata relevant to your system have been applied.

This update is available via Red Hat Network. Details on how to use the Red Hat Network to apply this update are available at This content is not included.https://access.redhat.com/kb/docs/DOC-11259
