The security advisory says that versions previous to Firefox 10, Thunderbird 10 and SeaMonkey 2.7 are unaffected by the use after free problem. The problem was discovered by Mozilla developers and causes a “potentially exploitable” crash in nsXBLDocumentInfo::ReadPrototypeBindings.

The H-Online: The Debian developers have pointed out, in an announcement on the debian-announce mailing list, that – three years after it was released –Debian GNU/Linux 5.0 (Lenny) has reached its “End of Life”. Debian GNU/Linux 5.0 was originally released in February 2009 and on 6 February 2012, the developers stopped providing security updates for that version of the distribution. Users have now had a year to update their systems to Lenny’s successor, Squeeze, which was released on 6 February 2011. The Debian developers recommend that any installations that are still using Debian 5.0 should be updated to version 6 of the distribution immediately. The Debian community recently released version 6.0.4 of Debian Squeeze which includes all the updates that have been released for Squeeze since its release. ...

SophosLabs: Can hackers really cause as much bloodshed as 353 Imperial Japanese Navy fighters, bombers and torpedo planes launched from six aircraft carriers? Can hackers really kill 2,402 U.S. citizens, leave 1,282 wounded, lose 65 of their own attackers in the process, and plunge the United States into a World War? Heaven only knows. Maybe they can. The lack of security around Supervisory Control And Data Acquisition (SCADA) systems is scary. ...

SophosLabs: Symantec has confirmed that a file made available on the internet for anyone to download, does contain the source code for an old version of its pcAnywhere product. For a short while last month, before releasing a patch, Symantec advised customers to disable their pcAnywhere installations because of concern that hackers could exploit vulnerabilities. In addition, the firm says that in January someone claiming to be the hacker responsible for the data theft tried to extort $50,000 from the firm in exchange for not releasing Symantec’s stolen source code. ...

Sunbelt: With the U.S. currently in tax season, online criminals have, once again, sought to take advantage of this. Robert Stetson, one of Sunbelt’s malware researchers, spotted a phishing email posing as Intuit Inc., a company that “develops financial and tax preparation software”. They developed Quicken and TurboTax. Below is a screenshot of the said email: Email details are as follows: Subject: Please verify your tax information ASAP. Message body: Good afternoon, ...

H-Online: Researchers at Ruhr-Universität Bochum in Germany have announced that they have cracked the A5-GMR-1 and A5-GMR-2 encryption algorithms used in satellite phones. Satellite phones are mainly used in areas with insufficient mobile network coverage and in the maritime sector. The researchers obtained the proprietary, and previously undocumented, algorithms by reverse engineering phone firmware updates. Ideally this, in itself, should not compromise the security of the transmitted data. Data security should not depend on the secrecy of the encryption methods, it should only depend on the non-disclosure of the secret key that is being used. ...

v3.co.uk: The uniform infrastructure and predictable behaviors are making corporate retail and restaurant chains the choice targets for cybercriminals. A report from security firm Trustwave found that attackers favor companies with chains of outlets, such as those commonly found in the food and retail industries, when launching targeted attacks. The attackers like the uniform IT infrastructure that large chains deploy at individual sites, Nicholas Percoco, head of the Trustwave’s SpiderLabs team, told V3. ...

The H-Online: Adobe has released a public beta of a sandboxed version of its Flash plugin for Firefox in an effort to improve its security. The new “Protected Mode” for Flash, which has been in development for at least a year according to Adobe engineer Peleus Uhley, runs with restricted privileges and, to further limit its access to the system, can only access system resources through a broker. This should help intercept attackers trying to gain access to a system through malicious Flash files. ...

The H-Online: RealNetworks has released an update to RealPlayer to close a number of holes in its media player application. Version 15.02.71 of RealPlayer addresses a total of seven remote code execution vulnerabilities, rated as highly critical by Secunia, which could be exploited by an attacker to compromise a victim’s system. These include errors when processing RMFF Flags, VIDOBJ_START_CODE and RealAudio coded_frame_size, as well as RV10 Encoded Height/Width, RV20 Frame Size Array and RV40 content. A remote code execution problem in Atrac Sample Decoding has also been fixed but is not found in the 15.x.x branch of the media player; this issue affects Mac RealPlayer 12.0.0.1701 but is reportedly not found in version 12.0.0.1703. ...

The H-Online: Versions 1.7.5 and 2.5.1 of the open source Joomla! content management system (CMS) have been released to address two information disclosure vulnerabilities. These include one medium severity problem in Joomla! 1.7.x that could allow an unauthorized user to gain access to the error log stored on a victim’s server, and, in both versions, an inadequate validation problem that could be exploited to gain access to private data. The update to Joomla! 2.5, which arrived last month, also fixes 30 bugs, including one that caused batch processing to break. ...
