Preallocated buffer overflows in XDR responses
A malicious server can crash the OpenAFS cache manager and other client utilities, and possibly execute arbitrary code.

Publication Mise à jourFileserver crash and possible information leak on StoreACL/FetchACL
An authenticated user can provide a malformed ACL to the fileserver's StoreACL RPC, causing the fileserver to crash, possibly expose uninitialized memory, and possibly store garbage data in the audit log. Malformed ACLs provided in responses to client FetchACL RPCs can cause client processes to crash and possibly expose uninitialized memory into other ACLs stored on the server.

Publication Mise à jourTheft of credentials in Unix client PAGs
A local user can bypass the OpenAFS PAG (Process Authentication Group) throttling mechanism in Unix clients, allowing the user to create a PAG using an existing id number, effectively joining the PAG and letting the user steal the credentials in that PAG.

Publication Mise à jourCVE-2019-18602
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.
- Mettez à jour vers 1.8.5-1
Publication Mise à jourCVE-2019-18603
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.
- Mettez à jour vers 1.8.5-1
Publication Mise à jourCVE-2019-18601
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.
- Mettez à jour vers 1.8.5-1
Publication Mise à jourCVE-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 and consume server resources waiting for those inputs, denying service to other valid connections.
- Mettez à jour vers 1.8.2-1
Publication Mise à jourCVE-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. 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.

Publication Mise à jourCVE-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, including dumping/restoring volume contents and manipulating the backup database. For example, an unauthenticated attacker can replace any volume's content with arbitrary data.
- Mettez à jour vers 1.8.2-1
Publication Mise à jourCVE-2017-17432
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.
- Mettez à jour vers 1.6.22-1
Publication Mise à jourCVE-2016-9772
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.
- Mettez à jour vers 1.6.20-1
Publication Mise à jourCVE-2016-4536
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.
- Mettez à jour vers 1.6.17-1
Publication Mise à jourCVE-2016-2860
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.
- Mettez à jour vers 1.6.17-1
Publication Mise à jourCVE-2015-8312
Off-by-one error in afs_pioctl.c in OpenAFS before 1.6.16 might allow local users to cause a denial of service (memory overwrite and system crash) via a pioctl with an input buffer size of 4096 bytes.
- Mettez à jour vers 1.6.17-1
Publication Mise à jourCVE-2015-7763
rx/rx.c in OpenAFS 1.5.75 through 1.5.78, 1.6.x before 1.6.15, and 1.7.x before 1.7.33 does not properly initialize padding at the end of an Rx acknowledgement (ACK) packet, which allows remote attackers to obtain sensitive information by (1) conducting a replay attack or (2) sniffing the network.
- Mettez à jour vers 1.6.15-1
Publication Mise à jourCVE-2015-7762
rx/rx.c in OpenAFS before 1.6.15 and 1.7.x before 1.7.33 does not properly initialize the padding of a data structure when constructing an Rx acknowledgement (ACK) packet, which allows remote attackers to obtain sensitive information by (1) conducting a replay attack or (2) sniffing the network.
- Mettez à jour vers 1.6.15-1
Publication Mise à jourCVE-2015-6587
The vlserver in OpenAFS before 1.6.13 allows remote authenticated users to cause a denial of service (out-of-bounds read and crash) via a crafted regular expression in a VL_ListAttributesN2 RPC.
- Mettez à jour vers 1.6.13-1
Publication Mise à jourCVE-2015-3285
The pioctl for the OSD FS command in OpenAFS before 1.6.13 uses the wrong pointer when writing the results of the RPC, which allows local users to cause a denial of service (memory corruption and kernel panic) via a crafted OSD FS command.
- Mettez à jour vers 1.6.13-1
Publication Mise à jourCVE-2015-3284
pioctls in OpenAFS 1.6.x before 1.6.13 allows local users to read kernel memory via crafted commands.
