Ubuntu 12.10 USN-1721-1 Moderate: Curl Malicious URL Threat

Scroller Ubuntu
Ensure your Ubuntu system is patched for the curl security flaw detected on February 12, 2013, by performing a system update.
curl could be made to crash or run programs if it opened a malicious URL.

Summary

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

Software Description:

- 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.
