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
