[DLA 558-1] squid security update
Package : squid
Version : 2.7.STABLE9-4.1+deb7u2
CVE ID : CVE-2016-4554
A security issue has been discovered in the Squid chaching proxy, on its
2.7.STABLE9 version branch.
CVE-2016-4554
Jianjun Chen found that Squid was vulnerable to a header smuggling
attack that could lead to cache poisoning and to bypass of same-origin
security policy in Squid and some client browsers.
For Debian 7 "Wheezy", this issue has been fixed in version
2.7.STABLE9-4.1+deb7u2.
We recommend that you upgrade your squid packages.

mode, an attacker can send malformed authentication packets which
break associations with the server for other broadcast clients.
CVE-2015-8138

validation of origin timestamps in ntpd clients may result in denial
of service.

symmetric mode, preventing time synchronisation.
CVE-2016-1550
Matthew van Gundy, Stephen Gray and Loganaden Velvindron discovered
that timing leaks in the the packet authentication code could result
in recovery of a message digest.
CVE-2016-2516

authentication to bypass intended access restrictions by logging in
as a user not in the cacti database.
CVE-2016-3172
An SQL injection vulnerability in tree.php allows remote authenticated
users to execute arbitrary SQL commands via the parent_id parameter in
an item_edit action.

[DSA 3628-1] perl security update
- -------------------------------------------------------------------------
Debian Security Advisory DSA-3628-1 security@debian.org
https://www.debian.org/security/ Salvatore Bonaccorso
July 25, 2016 https://www.debian.org/security/faq
- -------------------------------------------------------------------------
Package : perl
CVE ID : CVE-2016-1238 CVE-2016-6185
Debian Bug : 829578
Multiple vulnerabilities were discovered in the implementation of the
Perl programming language. The Common Vulnerabilities and Exposures
project identifies the following problems:
CVE-2016-1238
John Lightsey and Todd Rinaldo reported that the opportunistic
loading of optional modules can make many programs unintentionally
load code from the current working directory (which might be changed
to another directory without the user realising) and potentially
leading to privilege escalation, as demonstrated in Debian with
certain combinations of installed packages.
The problem relates to Perl loading modules from the includes
directory array ("@INC") in which the last element is the current
directory ("."). That means that, when "perl" wants to load a module
(during first compilation or during lazy loading of a module in run-
time), perl will look for the module in the current directory at the
end, since '.' is the last include directory in its array of include
directories to seek. The issue is with requiring libraries that are
in "." but are not otherwise installed.
With this update several modules which are known to be vulnerable
are updated to not load modules from current directory.
Additionally the update allows configurable removal of "." from @INC
in /etc/perl/sitecustomize.pl for a transitional period. It is
recommended to enable this setting if the possible breakage for a
specific site has been evaluated. Problems in packages provided in
Debian resulting from the switch to the removal of '.' from @INC
should be reported to the Perl maintainers at
perl@packages.debian.org .
It is planned to switch to the default removal of '.' in @INC in a
subsequent update to perl via a point release if possible, and in
any case for the upcoming stable release Debian 9 (stretch).
CVE-2016-6185
It was discovered that XSLoader, a core module from Perl to
dynamically load C libraries into Perl code, could load shared
library from incorrect location. XSLoader uses caller() information
to locate the .so file to load. This can be incorrect if
XSLoader::load() is called in a string eval. An attacker can take
advantage of this flaw to execute arbitrary code.
For the stable distribution (jessie), these problems have been fixed in
version 5.20.2-3+deb8u6. Additionally this update includes the
following updated packages to address optional module loading
vulnerabilities related to CVE-2016-1238, or to address build failures
which occur when '.' is removed from @INC:
- cdbs 0.4.130+deb8u1
- debhelper 9.20150101+deb8u2
- devscripts 2.15.3+deb8u1
- exim4 4.84.2-2+deb8u1
- libintl-perl 1.23-1+deb8u1
- libmime-charset-perl 1.011.1-1+deb8u2
- libmime-encwords-perl 1.014.3-1+deb8u1
- libmodule-build-perl 0.421000-2+deb8u1
- libnet-dns-perl 0.81-2+deb8u1
- libsys-syslog-perl 0.33-1+deb8u1
- libunicode-linebreak-perl 0.0.20140601-2+deb8u2
We recommend that you upgrade your perl packages.
