-------------------------------------------------------------------------------- Fedora Update Notification FEDORA-2017-9c6430c2e2 2017-04-22 03:35:57.950750 -------------------------------------------------------------------------------- Name : pcre2 Product : Fedora 25 Version : 10.23 Release : 6.fc25 URL : http://www.pcre.org/ Summary : Perl-compatible regular expression library Description : PCRE2 is a re-working of the original PCRE (Perl-compatible regular expression) library to provide an entirely new API. PCRE2 is written in C, and it has its own API. There are three sets of functions, one for the 8-bit library, which processes strings of bytes, one for the 16-bit library, which processes strings of 16-bit values, and one for the 32-bit library, which processes strings of 32-bit values. There are no C++ wrappers. This package provides support for strings in 8-bit and UTF-8 encodings. Install pcre2-utf16 or pcre2-utf32 packages for the other ones. The distribution does contain a set of C wrapper functions for the 8-bit library that are based on the POSIX regular expression API (see the pcre2posix man page). These can be found in a library called libpcre2posix. Note that this just provides a POSIX calling interface to PCRE2; the regular expressions themselves still follow Perl syntax and semantics. The POSIX API is restricted, and does not give full access to all of PCRE2's facilities. -------------------------------------------------------------------------------- Update Information: This release fixes a crash when finding a Unicode property for a character with a code point greater than 0x10ffff in UTF-32 library while UTF mode is disabled and JIT mode is enabled. It also fixes an incortect cast in UTF validation routine. -------------------------------------------------------------------------------- References: [ 1 ] Bug #1434504 - CVE-2017-7186 pcre: Invalid Unicode property lookup (8.41/7, 10.24/2) https://bugzilla.redhat.com/show_bug.cgi?id=1434504 -------------------------------------------------------------------------------- This update can be installed with the "dnf" update program. Use su -c 'dnf upgrade pcre2' at the command line.
