Description
Buffer overflow in net.c for cfengine 2.x before 2.0.8 allows remote attackers to execute arbitrary code via certain packets with modified length values, which is trusted by the ReceiveTransaction function when using a buffer provided by the BusyWithConnection function.
Public exploits
Exploit or proof-of-concept code for this vulnerability is publicly available, which lowers the bar for attackers. Treat it as a reason to patch sooner.
Third-party code, not reviewed by us. Public PoCs are sometimes fake or contain malware. Read the code first and run it only in an isolated lab, against systems you are authorised to test.
