USN-1721-1: curl vulnerability

12 February 2013

curl could be made to crash or run programs if it opened a malicious URL.

Releases

Packages

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

Details

It was discovered that curl incorrectly handled SASL authentication when
communicating over POP3, SMTP or IMAP. If a user or automated system were
tricked into processing a specially crafted URL, an attacker could cause
a denial of service, or possibly execute arbitrary code. The default
compiler options for affected releases should reduce the vulnerability to a
denial of service.

Update instructions

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

Ubuntu 12.10

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