Dist Fedora Esm H88
A patch for Fedora 22 resolves vulnerabilities in pcre, implementing essential corrections specifically for the processing of nested groups to prevent buffer overflow issues.
This release fixes a heap buffer overflow in handling of nested duplicate named groups with a nested back reference and a heap buffer overflow in pcretest causing infinite loop whe...

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 buffer overflow in handling of nested duplicate named groups with a nested back reference and a heap buffer overflow in pcretest causing infinite loop when matching globally with an ovector less than 2.
