Synopsis ========
A vulnerability in PCRE library allows remote attackers to cause a Denial of Service condition.
Background ==========
PCRE library is a set of functions that implement regular expression pattern matching using the same syntax and semantics as Perl 5.
Affected packages =================
------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 dev-libs/libpcre < 8.40-r1 >= 8.40-r1
Description ===========
It was found that the compile_bracket_matchingpath function in pcre_jit_compile.c in PCRE library is vulnerable to an out-of-bounds read.
Impact ======
A remote attacker could possibly cause a Denial of Service condition via a special crafted regular expression.
Workaround ==========
There is no known workaround at this time.
Resolution ==========
All PCRE library users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=dev-libs/libpcre-8.40-r1"
