Originalnachricht

Name        : pcre
Product : Fedora 22
Version : 8.38
Release : 1.fc22
URL : http://www.pcre.org/
Summary : Perl-compatible regular expression library
Description :
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 these vulnerabilies: CVE-2015-8383, CVE-2015-8386,
CVE-2015-8387, CVE-2015-8389, CVE-2015-8390, CVE-2015-8391, CVE-2015-8393,
CVE-2015-8394. It also fixes compiling comments with auto-callouts, compiling
expressions with negated classes in UCP mode, compiling expressions with an
isolated \E between an item and its qualifier with auto-callouts, a crash in
regexec() if REG_STARTEND option is set and pmatch argument is NULL, a stack
overflow when formatting a 32-bit integer in pcregrep tool, compiling
expressions with an empty \Q\E sequence between an item and its qualifier with
auto-callouts, compiling expressions with global extended modifier that is
disabled by local no-extended option at the start of the expression just after
a
whitespace, a possible crash in pcre_copy_named_substring() if a named
substring
has number greater than the space in the ovector, a buffer overflow when
compiling an expression with named groups with a group that reset capture
numbers, and a crash in pcre_get_substring_list() if the use of \K caused the
start of the match to be earlier than the end.
