Ubuntu 12.10 : curl vulnerability (USN-1721-1)

Ubuntu Security Notice (C) 2013 Canonical, Inc. / NASL script (C) 2013 Tenable Network Security, Inc.


Synopsis :

The remote Ubuntu host is missing one or more security-related patches.

Description :

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.

Solution :

Update the affected libcurl3, libcurl3-gnutls and / or libcurl3-nss
packages.

Risk factor :

High / CVSS Base Score : 7.5
(CVSS2#AV:N/AC:L/Au:N/C:P/I:P/A:P)
CVSS Temporal Score : 6.5
(CVSS2#E:ND/RL:OF/RC:C)
Public Exploit Available : true
