[SECURITY] [DSA 2301-1] rails security update

Debian Security Advisory DSA-2301-1 security@debian.org

Package : rails
Vulnerability : several
Problem type : remote
Debian-specific: no
CVE ID : CVE-2011-2930 CVE-2011-2931 CVE-2011-3186 CVE-2009-4214

Several vulnerabilities have been discovered in Rails, the Ruby web
application framework. The Common Vulnerabilities and Exposures project
identifies the following problems:

CVE-2009-4214

A cross-site scripting (XSS) vulnerability had been found in the
strip_tags function. An attacker may inject non-printable characters
that certain browsers will then evaluate. This vulnerability only
affects the oldstable distribution (lenny).

CVE-2011-2930

A SQL injection vulnerability had been found in the quote_table_name
method could allow malicious users to inject arbitrary SQL into a
query.

CVE-2011-2931

A cross-site scripting (XSS) vulnerability had been found in the
strip_tags helper. An parsing error can be exploited by an attacker,
who can confuse the parser and may inject HTML tags into the output
document.

CVE-2011-3186

A newline (CRLF) injection vulnerability had been found in
response.rb. This vulnerability allows an attacker to inject arbitrary
HTTP headers and conduct HTTP response splitting attacks via the
Content-Type header.

For the oldstable distribution (lenny), this problem has been fixed in
version 2.1.0-7+lenny1.

For the stable distribution (squeeze), this problem has been fixed in
version 2.3.5-1.2+squeeze1.

For the unstable distribution (sid), this problem has been fixed in
version 2.3.14.

We recommend that you upgrade your rails packages.

[SECURITY] [DSA 2300-2] nss security update

- -------------------------------------------------------------------------
Debian Security Advisory DSA-2300-2 security@debian.org
http://www.debian.org/security/ Thijs Kinkhorst

- -------------------------------------------------------------------------

Package : nss
Vulnerability : comprimised certificate authority
Problem type : local(remote)
Debian-specific: no
CVE ID : not available

Several unauthorised SSL certificates have been found in the wild issued
for the DigiNotar Certificate Authority, obtained through a security
compromise with said company. Debian, like other software
distributors, has as a precaution decided to disable the DigiNotar
Root CA by default in the NSS crypto libraries.

As a result from further understanding of the incident, this update
to DSA 2300 disables additional DigiNotar issuing certificates.

For the oldstable distribution (lenny), this problem has been fixed in
version 3.12.3.1-0lenny6.

For the stable distribution (squeeze), this problem has been fixed in
version 3.12.8-1+squeeze3.

For the unstable distribution (sid), this problem has been fixed in
version 3.12.11-2.

We recommend that you upgrade your nss packages.

[SECURITY] [DSA 2298-2] apache2 regression fix

- -------------------------------------------------------------------------
Debian Security Advisory DSA-2298-2 security@debian.org

Package : apache2
Vulnerability : denial of service
Problem type : remote
Debian-specific: no
CVE ID : CVE-2010-1452 CVE-2011-3192
Debian Bug : 639825

The apache2 Upgrade from DSA-2298-1 has caused a regression that
prevented some video players from seeking in video files served by
Apache HTTPD. This update fixes this bug.


The text of the original advisory is reproduced for reference:

Two issues have been found in the Apache HTTPD web server:

CVE-2011-3192

A vulnerability has been found in the way the multiple overlapping
ranges are handled by the Apache HTTPD server. This vulnerability
allows an attacker to cause Apache HTTPD to use an excessive amount of
memory, causing a denial of service.

CVE-2010-1452

A vulnerability has been found in mod_dav that allows an attacker to
cause a daemon crash, causing a denial of service. This issue only
affects the Debian 5.0 oldstable/lenny distribution.


The regression has been fixed in the following packages:

For the oldstable distribution (lenny), this problem has been fixed
in version 2.2.9-10+lenny11.

For the stable distribution (squeeze), this problem has been fixed in
version 2.2.16-6+squeeze3.

For the testing distribution (wheezy), this problem will be fixed in
version 2.2.20-1.

For the unstable distribution (sid), this problem has been fixed in
version 2.2.20-1.

We recommend that you upgrade your apache2 packages.

This update also contains updated apache2-mpm-itk packages which have
been recompiled against the updated apache2 packages. The new version
number for the oldstable distribution is 2.2.6-02-1+lenny6. In the
stable distribution, apache2-mpm-itk has the same version number as
apache2.
