Ubuntu 10.04 LTS / 12.04 LTS / 12.10 / 13.10 : curl vulnerabilities (USN-2167-1)
Medium Nessus Plugin ID 73514
SynopsisThe remote Ubuntu host is missing one or more security-related patches.
DescriptionSteve Holme discovered that libcurl incorrectly reused wrong connections when using protocols other than HTTP and FTP. This could lead to the use of unintended credentials, possibly exposing sensitive information. (CVE-2014-0138)
Richard Moore discovered that libcurl incorrectly validated wildcard SSL certificates that contain literal IP addresses. An attacker could possibly exploit this to perform a man in the middle attack to view sensitive information or alter encrypted communications.
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 libcurl3, libcurl3-gnutls and / or libcurl3-nss packages.
