Description:
Secunia Research has discovered a vulnerability in activePDF Server, which can be exploited by malicious people to compromise a vulnerable system.
The vulnerability is caused due to a boundary error in the activePDF Server service (APServer.exe) when receiving client data. This can be exploited to cause a heap-based buffer overflow by connecting to the service (port 53535/TCP by default) and sending a packet specifying a smaller size than the actual size of the following data.
Successful exploitation may allow execution of arbitrary code.
The vulnerability is confirmed in versions 3.8.4 and 3.8.5.14. Other versions may also be affected.
Solution:
Update to version 3.8.6.16 or later.
Provided and/or discovered by:
Carsten Eiram, Secunia Research.
