USN-1346-1: curl vulnerability

24 January 2012

curl could be tricked into injecting arbitrary data if it handled a malicious URL.



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


Dan Fandrich discovered that curl incorrectly handled URLs containing
embedded or percent-encoded control characters. If a user or automated
system were tricked into processing a specially crafted URL, arbitrary
data could be injected.

Update instructions

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

Ubuntu 11.10
Ubuntu 11.04
Ubuntu 10.10

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