Fedora 22: 2015-14235 Critical: Pcre Heap Overflow Issue

fedora
Calendar Grey September 11, 2015
Dist Fedora Esm H88
Fedora 22 refreshes pcre to resolve buffer overflow vulnerability in named references pertaining to regex patterns.
This release fixes a heap overflow when compiling certain regular expressions with named refecences.

Summary

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 release fixes a heap overflow when compiling certain regular expressions with named refecences.
