RHBA-2013:1298 - pcre bug fix update

Synopsis

pcre bug fix update

Type/Severity

Bug Fix Advisory (none)

Topic

Updated pcre packages that fix several bugs are now available for Red Hat Enterprise Linux 5.

Description

The pcre packages provide the Perl-compatible regular expression (PCRE) library.

This update fixes the following bugs:

  • A previous update enabled Unicode properties to support \p{..}, \P{..}, and \X escape sequences. However, compiling certain regular expressions which contained extended classes under a non-UTF-8 PCRE mode failed due to the compilation entering an infinite loop. This has been fixed in this update so that compiling such regular expressions completes as expected. (BZ#669413)

  • Using the pcregrep tool with -M (mutli-line match) and -v (inverse match) options caused the pcregrep tool to loop infinitely. With this update, the pcregrep multi-line loop logic has been fixed to advance in the input stream properly if inverted matching is requested, and it is now possible to use the "pcregrep -Mv" command. (BZ#859959)

  • Previously, matching a regular expression with Unicode properties in a non-UTF-8 mode against a string with non-ASCII characters, caused an unexpected termination with a segmentation fault in the PCRE library. This update fixes back-tracking in non-UTF-8 mode, and the PCRE library no longer crashes in the aforementioned scenario. (BZ#866520)

Users of pcre are advised to upgrade to these updated packages, which fix these bugs.
