DSA-1946 belpic - cryptographic weakness

It was discovered that belpic, the belgian eID PKCS11 library, does not
properly check the result of an OpenSSL function for verifying
cryptographic signatures, which could be used to bypass the certificate
validation.

DSA-1945 gforge - symlink attack

Sylvain Beucler discovered that gforge, a collaborative development
tool, is prone to a symlink attack, which allows local users to perform
a denial of service attack by overwriting arbitrary files.

DSA-1944 request-tracker3.4 request-tracker3.6 - session hijack

Mikal Gule discovered that request-tracker, an extensible trouble-ticket
tracking system, is prone to an attack, where an attacker with access
to the same domain can hijack a user's RT session.

DSA-1943 openldap openldap2.3 - insufficient input validation

It was discovered that OpenLDAP, a free implementation of the Lightweight
Directory Access Protocol, when OpenSSL is used, does not properly handle a '\0'
character in a domain name in the subject's Common Name (CN) field of an ... [More] X.509
certificate, which allows man-in-the-middle attackers to spoof arbitrary SSL
servers via a crafted certificate issued by a legitimate Certification Authority. [Less]

DSA-1942 wireshark - several vulnerabilities

Several remote vulnerabilities have been discovered in the Wireshark
network traffic analyzer, which may lead to the execution of arbitrary
code or denial of service. The Common Vulnerabilities and Exposures
project identifies the following problems:

DSA-1940 php5 - multiple issues

Several remote vulnerabilities have been discovered in the PHP 5
hypertext preprocessor. The Common Vulnerabilities and Exposures
project identifies the following problems:

DSA-1941 poppler - several vulnerabilities

Several integer overflows, buffer overflows and memory allocation
errors were discovered in the Poppler PDF rendering library, which may
lead to denial of service or the execution of arbitrary code if a user
is tricked into opening a malformed PDF document.

DSA-1939 libvorbis - several vulnerabilities

Lucas Adamski, Matthew Gregan, David Keeler, and Dan Kaminsky discovered
that libvorbis, a library for the Vorbis general-purpose compressed
audio codec, did not correctly handle certain malformed ogg files. An
attacher could cause a ... [More] denial of service (memory corruption and
application crash) or possibly execute arbitrary code via a crafted .ogg
file. [Less]

DSA-1938 php-mail - programming error

It was discovered that php-mail, a PHP PEAR module for sending email,
has insufficient input sanitising, which might be used to obtain
sensitive data from the system that uses php-mail.

tmpreaper: keep your temp files under control

The tmpreaper utility will clean out your temporary file directories by recursively removing files that haven’t been accessed in some amount of time. You can configure exclusions and it will not dive into symlinks, or remove symlinks, sockets ... [More] , FIFOs, or special files unless specifically told to.

However, the package description contains this:

WARNING: Please do not run `tmpreaper’ on `/’. There are no protections against this written into the program, as that would prevent it from functioning the way you’d expect it to in a `chroot(8)’ environment.

After you install the package, you need to manually edit /etc/tmpreaper.conf and remove or comment the SHOWWARNING=true line to actually active it. Also review the settings in that file.

At least some versions of Ubuntu, and possibly Debian, do not install tmpreaper by default. I assume that is in accordance with the “principle of least surprise” but this policy may bother system administrators familiar with Red Hat or other systems where /tmp is automatically cleaned out by default. Note that /tmp and other directories are still cleaned at boot-time by the default /etc/init.d/bootclean (Debian) or /etc/init.d/*-bootclean.sh (Ubuntu) scripts.

The Red Hat and derivatives equivalent is ‘tmpwatch’ and is installed by default on those systems. [Less]
