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.
