The Common Vulnerabilities and Exposures project identifies the following problems: CVE-2018-16947 Jeffrey Altman reported that the backup tape controller (butc) process does accept incoming RPCs but does not require (or allow for) authentication of those RPCs, allowing an unauthenticated attacker to perform volume operations with administrator credentials. https://openafs.org/pages/security/OPENAFS-SA-2018-001.txt CVE-2018-16948 Mark Vitale reported that several RPC server routines do not fully initialize output variables, leaking memory contents (from both the stack and the heap) to the remote caller for otherwise-successful RPCs. https://openafs.org/pages/security/OPENAFS-SA-2018-002.txt CVE-2018-16949 Mark Vitale reported that an unauthenticated attacker can consume large amounts of server memory and network bandwidth via specially crafted requests, resulting in denial of service to legitimate clients. https://openafs.org/pages/security/OPENAFS-SA-2018-003.txt For the stable distribution (stretch), these problems have been fixed in version 1.6.20-2+deb9u2. We recommend that you upgrade your openafs packages.
