Ubuntu Security Notice USN-1800-1

haproxy vulnerabilities
==========================================================================

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 12.10
- Ubuntu 12.04 LTS
- Ubuntu 11.10

Summary:

HAProxy could be made to crash or run programs if it received specially
crafted network traffic.

Software Description:
- haproxy: fast and reliable load balancing reverse proxy

Details:

It was discovered that HAProxy incorrectly handled configurations where
global.tune.bufsize was set to a value higher than the default. A remote
attacker could use this issue to cause a denial of service, or possibly
execute arbitrary code. (CVE-2012-2942)

Yves Lafon discovered that HAProxy incorrectly handled HTTP keywords in TCP
inspection rules when HTTP keep-alive is enabled. A remote attacker could
use this issue to cause a denial of service, or possibly execute arbitrary
code. (CVE-2013-1912)

Update instructions:

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

Ubuntu 12.10:
haproxy 1.4.18-0ubuntu2.1

Ubuntu 12.04 LTS:
haproxy 1.4.18-0ubuntu1.1

Ubuntu 11.10:
haproxy 1.4.15-1ubuntu0.1

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

Ubuntu Security Notice USN-1801-1
April 16, 2013

curl vulnerability
==========================================================================

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 12.10
- Ubuntu 12.04 LTS
- Ubuntu 11.10
- Ubuntu 10.04 LTS
- Ubuntu 8.04 LTS

Summary:

Applications using libcurl could be made to expose sensitive information
over the network.

Software Description:
- curl: HTTP, HTTPS, and FTP client and client libraries

Details:

YAMADA Yasuharu discovered that libcurl was vulnerable to a cookie
leak when doing requests across domains with matching tails. curl did
not properly restrict cookies to domains and subdomains. If a user or
automated system were tricked into processing a specially crafted URL,
an attacker could read cookie values stored by unrelated webservers.

Update instructions:

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

Ubuntu 12.10:
curl 7.27.0-1ubuntu1.2
libcurl3 7.27.0-1ubuntu1.2

Ubuntu 12.04 LTS:
curl 7.22.0-3ubuntu4.1
libcurl3 7.22.0-3ubuntu4.1

Ubuntu 11.10:
curl 7.21.6-3ubuntu3.3
libcurl3 7.21.6-3ubuntu3.3

Ubuntu 10.04 LTS:
curl 7.19.7-1ubuntu1.2
libcurl3 7.19.7-1ubuntu1.2

Ubuntu 8.04 LTS:
curl 7.18.0-1ubuntu2.4
libcurl3 7.18.0-1ubuntu2.4

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