Scientific Linux Security Update : Moderate: OpenAFS on SL6.x, SL7.x i386/x86_64 (20180911)

These releases include fixes for three security advisories, OPENAFS-SA-2018-001, OPENAFS-SA-2018-002, and OPENAFS-SA-2018-003. OPENAFS-SA-2018-001 only affects deployments that run the 'butc' utility as part of the in-tree backup system, but is of high severity for those sites which are affected ...

Design/Logic Flaw

An issue was discovered in OpenAFS before 1.6.23 and 1.8.x before 1.8.2. Several RPC server routines did not fully initialize their output variables before returning, leaking memory contents from both the stack and the heap. Because the OpenAFS cache manager functions as an Rx server for the AFSC...

CVE-2018-16949

An issue was discovered in OpenAFS before 1.6.23 and 1.8.x before 1.8.2. Several data types used as RPC input variables were implemented as unbounded array types, limited only by the inherent 32-bit length field to 4 GB. An unauthenticated attacker could send, or claim to send, large input values...

CVE-2018-16947

An issue was discovered in OpenAFS before 1.6.23 and 1.8.x before 1.8.2. The backup tape controller butc process accepts incoming RPCs but does not require or allow for authentication of those RPCs. Handling those RPCs results in operations being performed with administrator credentials, includin...

CVE-2018-16948

An issue was discovered in OpenAFS before 1.6.23 and 1.8.x before 1.8.2. Several RPC server routines did not fully initialize their output variables before returning, leaking memory contents from both the stack and the heap.

Authentication flaw

An issue was discovered in OpenAFS before 1.6.23 and 1.8.x before 1.8.2. The backup tape controller butc process accepts incoming RPCs but does not require or allow for authentication of those RPCs. Handling those RPCs results in operations being performed with administrator credentials, includin...

Input validation

CVE-2018-16949

OpenAFS contains a vulnerability (CVE-2018-16949) where several RPC input variables are defined as unbounded arrays, only limited by the 4 GB length field. An unauthenticated attacker could send large inputs to exhaust server resources and cause denial of service. Affected versions are OpenAFS be...
