The remote host is affected by the vulnerability described in GLSA-200601-14 (LibAST: Privilege escalation)
Michael Jennings discovered an exploitable buffer overflow in the configuration engine of LibAST.
Impact :
The vulnerability can be exploited to gain escalated privileges if the application using LibAST is setuid/setgid and passes a specifically crafted filename to LibAST's configuration engine.
Workaround :
Identify all applications linking against LibAST and verify they are not setuid/setgid.
