RHBA-2012:0887 - libunistring bug fix update


Synopsis

libunistring bug fix update

Type/Severity

Bug Fix Advisory

Topic

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

Description

The libunistring package contains a portable C library that implements the UTF-8, UTF-16 and UTF-32 Unicode string types, together with functions for character processing (names, classifications, and properties) and functions for string processing (iteration, formatted output, width, word breaks, line breaks, normalization, case folding, and regular expressions).

This update fixes the following bug:

  • Previously, when calling the malloc() function, no check for the returned pointer was performed to find out whether memory was successfully allocated. Therefore, if a null pointer was returned, this could cause the libunistring library to misbehave in low-memory situations. This update adds the missing check to properly handle such situations. (BZ#732017)

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

Solution

Before applying this update, make sure that 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 https://access.redhat.com/knowledge/articles/11258
