Enhancement Advisory libnih enhancement update

Advisory: RHEA-2011:1672-2
Type: Product Enhancement Advisory
Severity: N/A
Issued on: 2011-12-06
Last updated on: 2011-12-06
Affected Products: Red Hat Enterprise Linux Desktop (v. 6)
Red Hat Enterprise Linux HPC Node (v. 6)
Red Hat Enterprise Linux Server (v. 6)
Red Hat Enterprise Linux Workstation (v. 6)

Details

An updated libnih package that adds one enhancement is now available for Red Hat
Enterprise Linux 6.

The libnih package includes a small library for C application development. The
library is similar to other C libraries, such as glib.

This update adds the following enhancement:

* Previously, the libnih package was compiled without the read-only relocations
(RELRO) flag. Programs built against the libnih library could be vulnerable to
various attacks based on overwriting the ELF section of a program. To enhance
the security, the libnih package is now provided with partial RELRO support.
(BZ#727284)

All users of libnih are advised to upgrade to this updated package, which adds
this enhancement.
