This thread allocates a buffer for the incoming packet and one extra byte. This buffer is then filled with multiple calls to recv which will result in an arbitrary size heap overflow.
When reading an oversized keyname a standard stackoverflow can be triggered. The code below is part of Trillian since version 0. It was manually decompiled. The variable names were taken from the GAIM source code. If you compare the decompiled code with the code in yahoo. It is up to the reader to find an explanation how this GPL licensed codesnippet ended up in Trillian.
It is not known what and why Yahoo! We were only able to exploit the vulnerability with man in the middle attacks. This can be considered good news because this will make it impossible to write a widespread worm.
Although Trillian Pro is compiled with the Visual Studio stackoverflow protection it is possible to exploit this vulnerability by simply overflowing up to the stack top and abusing the power of structured exception handlers. Proof of Concept: e-matters is not going to release an exploit for any of these vulnerabilities to the public. This may also be the case with other accounts etc, but like I said I have not looked into it much.
Just wanted to make aware of this as a great number of people use Yahoo for money, and business purposes as well as personal use. Solution: I contacted Cerulean Studios a week or two ago about this, but I have not heard back from them at all.
I would suggest not using this particular feature or shredding the temp file at best after logging in if you REALLY insist on using this feature. But that doesnt stop the credentials from being passed over the network in plaintext I imagine the guys at Cerulean Studios get swamped with emails, thus the no reply. Kali Linux. Penetration Testing. The new SMS to text features are fantastic! Trillian has been great. The alternative we looked at, Slack, just has too many features, is too expensive, and does way more than what we needed.
Trillian is perfect for our basic inter-office needs. They keep the client software regularly updated which is nice, and their servers have excellent uptime. We rarely, if ever, experience outages. It's absolutely a five star product.
Our practice management system has a communication module, but it only sends messages to the front desk - the front desk can't reply! We needed to have an actual running conversation, and also for different people to interact privately outside of a group conversation.
