Description
Heap-based buffer overflow in the AuthenticationDialogue function in cfservd for Cfengine 2.0.0 to 2.1.7p1 allows remote attackers to execute arbitrary code via a long SAUTH command during RSA authentication.
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.
