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.

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 VLListAttributesN2 RPC.

Buffer overflow in the Solaris kernel extension in OpenAFS before 1.6.13 allows local users to cause a denial of service (panic or deadlock) or possibly have other unspecified impact via a large group list when joining a PAG.

OpenAFS before 1.6.13 allows remote attackers to spoof bos commands via unspecified vectors.

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.

vos in OpenAFS before 1.6.13, when updating VLDB entries, allows remote attackers to obtain stack data by sniffing the network.

pioctls in OpenAFS 1.6.x before 1.6.13 allows local users to read kernel memory via crafted commands.
