-------------------------------------------------------------------------------- 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. -------------------------------------------------------------------------------- ChangeLog: * Tue Feb 12 2008 Tomas Hoger <thoger@redhat.com> - 7.3-3 - Backport patch from upstream pcre 7.6 to address buffer overflow caused by "a character class containing a very large number of characters with codepoints greater than 255 (in UTF-8 mode)" CVE-2008-0674, #431660 - Try re-enabling make check again. * Fri Nov 16 2007 Stepan Kasal <skasal@redhat.com> - 7.3-2 - Remove obsolete ``reqs'' - add dist tag - update BuildRoot * Mon Sep 17 2007 Than Ngo <than@redhat.com> - 7.3-1 - bz292501, update to 7.3 -------------------------------------------------------------------------------- References: [ 1 ] Bug #315871 - CVE-2007-1659 pcre regular expression flaws https://bugzilla.redhat.com/show_bug.cgi?id=315871 [ 2 ] Bug #392891 - CVE-2007-4766: pcre < 7.3 integer overflows https://bugzilla.redhat.com/show_bug.cgi?id=392891 [ 3 ] Bug #392901 - CVE-2007-4767: pcre < 7.3 \p, \P, \P{x] length calculation issue https://bugzilla.redhat.com/show_bug.cgi?id=392901 [ 4 ] Bug #392911 - CVE-2007-4768: pcre before 7.3 incorrect unicode in char class optimization https://bugzilla.redhat.com/show_bug.cgi?id=392911 [ 5 ] Bug #392921 - CVE-2007-1662: pcre < 7.3 unmatched bracket/paren past EoS read issue https://bugzilla.redhat.com/show_bug.cgi?id=392921 [ 6 ] Bug #392931 - CVE-2007-1661: pcre < 7.3 non-UTF-8 over-backtracking issue https://bugzilla.redhat.com/show_bug.cgi?id=392931 [ 7 ] Bug #431660 - pcre: buffer overflow via large UTF-8 character class https://bugzilla.redhat.com/show_bug.cgi?id=431660 -------------------------------------------------------------------------------- This update can be installed with the "yum" update program.
