    CVE-2015-8853

    Summary: Updated perl packages fix security vulnerability

    Details: 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 (CVE-2015-8853).
