CVE-2015-8388
CVSS v2.0
7.5
Alta
| Vetor | AV:N/AC:L/Au:N/C:P/I:P/A:P |
Name of the Vulnerable Software and Affected Versions
PCRE versions prior to 8.38
Description
The issue concerns the mishandling of certain patterns, such as /(?=di(?<=(?1))|(?=(.))))/, which contain an unmatched closing parenthesis. This allows remote attackers to cause a denial of service, potentially leading to a buffer overflow, or possibly have other unspecified impacts through a crafted regular expression. This has been demonstrated using a JavaScript RegExp object encountered by Konqueror.
Recommendations
For versions prior to 8.38, update to version 8.38 or later to resolve the issue.
Correção
DoS
Buffer Overflow
