Fedora 23: 2015-14229 Moderate Pcre Heap Overflow Security Update

fedora
Calendar Grey August 27, 2015
Dist Fedora Esm H88
The Fedora 23 upgrade addressed vulnerabilities related to heap and stack overflows in the pcre regex library, thereby improving system security.
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. This release fixes buffer overflows when compiling certain expressions.
