CVE-2017-6004 low priority: Ubuntu including 1 source packages (pcre3), 17 status rows across 17 suites (artful, bionic, cosmic, disco, eoan, focal, groovy, hirsute, impish, jammy, kinetic, precise, trusty, upstream, xenial, yakkety, zesty): not-affected 14, released 2, ignored 1.
The compile_bracket_matchingpath function in pcre_jit_compile.c in PCRE through 8.x before revision 1680 (e.g., the PHP 7.1.1 bundled version) allows remote attackers to cause a denial of service (out-of-bounds read and application crash) via a crafted regular expression.
