Description

PCRE before 8.38 mishandles the interaction of lookbehind assertions and mutually recursive subpatterns, which allows remote attackers to cause a denial of service (buffer overflow) or possibly have unspecified other impact via a crafted regular expression, as demonstrated by a JavaScript RegExp object encountered by Konqueror.

Affected configurations

• pcre perl compatible regular expression library (<= 8.37) • fedoraproject fedora 22 • oracle linux 7 • php php (>= 5.5.0 < 5.5.32) • php php (>= 5.6.0 < 5.6.18) • php php (>= 7.0.0 < 7.0.3)
