Fedora 23: 2016-12035 Major: PCRE Security Update Implementation

fedora
Calendar Grey July 13, 2015
Scroller Fedora
Memory corruption vulnerabilities addressed in pcre for Fedora 22, enhancing both security and performance following this enhancement.
This release fixes two heap buffer overflows when compiling certain regular expressions: CVE-2015-3210 and CVE-2015-5073.

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 two heap buffer overflows when compiling certain regular expressions: CVE-2015-3210 and CVE-2015-5073.
