The pcre_exec function in pcre_exec.c in PCRE before 8.38 mishandles a // pattern with a \01 string, which allows remote attackers to cause a denial of service (heap-based buffer overflow) or possibly have unspecified other impact via a crafted regular expression, as demonstrated by a JavaScript RegExp object encountered by Konqueror.

Примечания
For wheezy: same code looks present around patched lines, though the
reproducer does not lead to a crash, and just gives
"Matched, but too many substrings"
Fixed in 8.38 upstream
