[GLSA-200701-22] Squid: Multiple Denial of Service vulnerabilities |
||
Squid: Multiple Denial of Service vulnerabilities Detailed Explanation for this Vulnerability Assessment The remote host is affected by the vulnerability described in GLSA-200701-22 (Squid: Multiple Denial of Service vulnerabilities) Squid fails to correctly handle ftp:// URI's. There is also an error in the external_acl queue which can cause an infinite looping condition. Impact A possible hacker could attempt to retrieve a specially crafted URI via a Squid server causing the service to crash. If a possible hacker could generate a sufficiently high load on the Squid services, they could cause a Denial of Service by forcing Squid into an infinite loop. Workaround There is no known workaround at this time.
