Ubuntu Security Notice USN-1721-1
12th February, 2013
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 12.10
curl could be made to crash or run programs if it opened a malicious URL.
- curl - HTTP, HTTPS, and FTP client and client libraries
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.
The problem can be corrected by updating your system to the following package version:
- Ubuntu 12.10:
- libcurl3-nss 7.27.0-1ubuntu1.1
- libcurl3-gnutls 7.27.0-1ubuntu1.1
- libcurl3 7.27.0-1ubuntu1.1
To update your system, please follow these instructions: https://wiki.ubuntu.com/Security/Upgrades.
In general, a standard system update will make all the necessary changes.
