Ubuntu 8.04 LTS / 10.04 LTS / 11.10 / 12.04 LTS / 12.10 : curl vulnerability (USN-1801-1)
Medium Nessus Plugin ID 65981
SynopsisThe remote Ubuntu host is missing one or more security-related patches.
DescriptionYAMADA Yasuharu discovered that libcurl was vulnerable to a cookie leak when doing requests across domains with matching tails. curl did not properly restrict cookies to domains and subdomains. If a user or automated system were tricked into processing a specially crafted URL, an attacker could read cookie values stored by unrelated webservers.
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.
SolutionUpdate the affected curl and / or libcurl3 packages.
