Ubuntu 10.04 LTS / 12.04 LTS / 12.10 / 13.04 : curl vulnerability (USN-1894-1)

Medium Nessus Plugin ID 67138


The remote Ubuntu host is missing one or more security-related patches.


Timo Sirainen discovered that libcurl incorrectly handled memory when parsing URL encoded strings. An attacker could possibly use this issue to cause libcurl to crash, leading to a denial of service, or execute arbitrary code.

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.


Update the affected libcurl3, libcurl3-gnutls and / or libcurl3-nss packages.
