A take on the security news, week 50

Wed 10 December 2014

A take on the security news, week 50 / 2014. I summarize some of the news that I considered noteworthy related to information security this week.

Yosemite logging input to /tmp, Patch tuesday, Poodle bites again, Hijacking putty sessions and a Wordpress XSS attack.

  • Monday

Yosemite Apple CoreGraphics are logging to /tmp

It is discovered that CoreGraphics on osx 10.10 have logging turned "on" by default (it was "off" in earlier versions of osx). These log files contain a record of all inputs into Mozilla programs during their operation.

If you are affected, go to your /tmp folder and delete occurences of CGLog_mozilla product, i.e CGLog_firefox.

Updating Firefox (FF34, FF ESR 31.3) and Thunderbird (TB 31.3) will fix the problem by turning CoreGraphics logging "off" again.

The poodle bites again

Its discovered that despite the removal of SSL3, there is still sites that are vulnerable to the Poodle attack. This comes from the fact that the TLS's padding is a subset of SSL3's padding and its therefore a technical possibility that you can use a SSL3 decoding function with TLS. It was found that a number of major sites had this problem and the hosting of the sites are contacted.

Details and mitigations are available in the links below:

Protocol handling issues in X servers

The vulnerability can be exploited to access uninitialized memory, or overwrite arbitrary memory, leading to denial of service or arbitrary code execution.

Mitigation is prohibiting x-connections from the network by setting "-nolisten tcp" and/or disable GLX indirect contexts.

InfiniteWP SQL Injection

A missing escaping of user-input allow for a sql-injection attack in the Wordpress administration tool InfiniteWP. There is also another issue related to improper hashing of passwords, which can lead to passwords be cracked. The password are stored as unsalted SHA1 hashes.

Puttyrider, a tool for hicjacking putty sessions

This is a tool that let let you sniff and insert commands into an existing putty session. The idea is that an attacker can attack the sysadmin's Windows machine and then wait for putty sessions from the sysadmin's machine to the server. When this happens he can hicjack the session and inject shell commands with the priviligies of the sysadmin.
