Linux Advisory Watch Thank you for reading the Linux Advisory Watch Security Newsletter. The purpose of this document is to provide our readers with a quick summary of each week's vendor security bulletins and pointers on methods to improve the security posture of your open source system. Vulnerabilities affect nearly every vendor virtually every week, so be sure to read through to find the updates your distributor have made available.

Password guessing as an attack vector - Using password guessing as an attack vector. Over the years we've been taught a strong password must be long and complex to be considered secure. Some of us have taken that notion to heart and always ensure our passwords are strong. But some don't give a second thought to the complexity or length of our password.

Squid and Digest Authentication - Digest AuthenticationDigest Authentication hashes the password before transmitting over the wire. Essentially it sends a message digest generated from multiple items including username, realm and nonce value. If you want to know more see (RFC 2617).


  Debian: 2381-1: squid3: invalid memory deallocation (Jan 6)
 

It was discovered that the IPv6 support code in Squid does not properly handle certain DNS responses, resulting in deallocation of an invalid pointer and a daemon crash. [More...]

  Debian: 2380-1: foomatic-filters: shell command injection (Jan 4)
 

It was discovered that the foomatic-filters, a support package for setting up printers, allowed authenticated users to submit crafted print jobs which would execute shell commands on the print servers. [More...]

  Debian: 2379-1: krb5: Multiple vulnerabilities (Jan 4)
 

It was discovered that the Key Distribution Center (KDC) in Kerberos 5 crashes when processing certain crafted requests: CVE-2011-1528 [More...]

  Debian: 2378-1: ffmpeg: Multiple vulnerabilities (Jan 3)
 

Several vulnerabilities have been discovered in ffmpeg, a multimedia player, server and encoder. Multiple input validations in the decoders for QDM2, VP5, VP6, VMD and SVQ1 files could lead to the execution of arbitrary code. [More...]

  Debian: 2377-1: cyrus-imapd-2.2: NULL pointer dereference (Jan 1)
 

It was discovered that cyrus-imapd, a highly scalable mail system designed for use in enterprise environments, is not properly parsing mail headers when a client makes use of the IMAP threading feature. As a result, a NULL pointer is dereferenced which crashes the daemon. An attacker can trigger [More...]

  Debian: 2376-2: ipmitool: insecure pid file (Dec 31)
 

It was discovered that OpenIPMI, the Intelligent Platform Management Interface library and tools, used too wide permissions PID file, which allows local users to kill arbitrary processes by writing to this file. [More...]

A vulnerability has been found and corrected in fcgi: The FCGI (aka Fast CGI) module 0.70 through 0.73 for Perl, as used by CGI::Fast, uses environment variable values from one request during processing of a later request, which allows remote attackers to bypass [More...]

  Mandriva: 2011:198: phpmyadmin (Dec 31)
 

Multiple vulnerabilities has been found and corrected in phpmyadmin: Importing a specially-crafted XML file which contains an XML entity injection permits to retrieve a local file (limited by the privileges of the user running the web server) (CVE-2011-4107). [More...]
