CVE-2015-8853 [HIGH] CVE-2015-8853 perl: regexp matching hangs indefinitely on illegal UTF-8 input
CVE-2015-8853 perl: regexp matching hangs indefinitely on illegal UTF-8 input
A vulnerability was found in perl. The regex engine got into an infinite loop because of the malformation. It is trying to back-up over a sequence of UTF-8 continuation bytes. The character just before the sequence should be a start byte. If it's not, there is a malformation which results in "hang" of regexp matching and CPU exhaustion.
