[SECURITY] Fedora 7 Update: pcre-7.3-3.fc7



--------------------------------------------------------------------------------
Fedora Update Notification
FEDORA-2008-1842
2008-03-06 16:11:59
--------------------------------------------------------------------------------

Name        : pcre
Product     : Fedora 7
Version     : 7.3
Release     : 3.fc7
URL         : http://www.pcre.org/
Summary     : Perl-compatible regular expression library
Description :
Perl-compatible regular expression library.
PCRE has its own native API, but a set of "wrapper" functions that are based on
the POSIX API are also supplied in the library libpcreposix. Note that this
just provides a POSIX calling interface to PCRE: the regular expressions
themselves still follow Perl syntax and semantics. The header file
for the POSIX-style functions is called pcreposix.h.

--------------------------------------------------------------------------------
Update Information:

This update re-based pcre to version 7.3 as used in Fedora 8 to address multiple
security issues that cause memory corruption, leading to application crash or
possible execution of arbitrary code.    CVE-2007-1659 (#315871), CVE-2007-1661
(#392931), CVE-2007-1662 (#392921), CVE-2007-4766 (#392891), CVE-2007-4767
(#392901), CVE-2007-4768 (#392911), CVE-2008-0674 (#431660)    This issue may
affect usages of pcre, where regular expressions from untrusted sources are
compiled.  Handling of untrusted data using trusted regular expressions is not
affected by these problems.
--------------------------------------------------------------------------------
