Openafs: >> Openafs >> 1.0 Security Vulnerabilities
OpenAFS before 1.6.24 and 1.8.x before 1.8.5 is prone to denial of service from unserialized data access because remote attackers can make a series of VOTE_Debug RPC calls to crash a database server within the SVOTE_Debug RPC handler.

OpenAFS before 1.6.24 and 1.8.x before 1.8.5 is prone to an information disclosure vulnerability because uninitialized scalars are sent over the network to a peer.

OpenAFS before 1.6.24 and 1.8.x before 1.8.5 is prone to information leakage upon certain error conditions because uninitialized RPC output variables are sent over the network to a peer.

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, including dumping/restoring volume contents and manipulating the backup database. For example, an unauthenticated attacker can replace any volume's content with arbitrary data.

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 AFSCB service, clients are also susceptible to information leakage. For example, RXAFSCB_TellMeAboutYourself leaks kernel memory and KAM_ListEntry leaks kaserver memory.

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 and consume server resources waiting for those inputs, denying service to other valid connections.

OpenAFS 1.x before 1.6.22 does not properly validate Rx ack packets, which allows remote attackers to cause a denial of service (system crash or application crash) via crafted fields, as demonstrated by an integer underflow and assertion failure for a small MTU value.

OpenAFS 1.6.19 and earlier allows remote attackers to obtain sensitive directory information via vectors involving the (1) client cache partition, (2) fileserver vice partition, or (3) certain RPC responses.

The client in OpenAFS before 1.6.17 does not properly initialize the (1) AFSStoreStatus, (2) AFSStoreVolumeStatus, (3) VldbListByAttributes, and (4) ListAddrByAttributes structures, which might allow remote attackers to obtain sensitive memory information by leveraging access to RPC call traffic.

The newEntry function in ptserver/ptprocs.c in OpenAFS before 1.6.17 allows remote authenticated users from foreign Kerberos realms to bypass intended access restrictions and create arbitrary groups as administrators by leveraging mishandling of the creator ID.
