16 April 2013

Applications using libcurl could be made to expose sensitive information over the network.

Releases

Packages

  • curl - HTTP, HTTPS, and FTP client and client libraries

Details

YAMADA 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.

Update instructions

The problem can be corrected by updating your system to the following package versions:

Ubuntu 8.04
Ubuntu 12.10
Ubuntu 12.04
Ubuntu 11.10
Ubuntu 10.04

In general, a standard system update will make all the necessary changes.
