Ubuntu 6.06 LTS / 6.10 : squid vulnerabilities (USN-414-1)
Medium Nessus Plugin ID 28003
SynopsisThe remote Ubuntu host is missing one or more security-related patches.
DescriptionDavid Duncan Ross Palmer and Henrik Nordstrom discovered that squid incorrectly handled special characters in FTP URLs. Remote users with access to squid could crash the server leading to a denial of service.
Erick Dantas Rotole and Henrik Nordstrom discovered that squid could end up in an endless loop when exhausted of available external ACL helpers. Remote users with access to squid could cause CPU starvation, possibly leading to a denial of service. This does not affect a default Ubuntu installation, since external ACL helpers must be configured and used. (CVE-2007-0248).
Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
