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.

Updated openafs packages fix security vulnerabilities
Updated openafs packages fix security vulnerabilities:
When constructing an Rx acknowledgment (ACK) packet, Andrew-derived Rx implementations do not initialize three octets of data that are padding in the C language structure and were inadvertently included in the wire protocol (CVE-2015-7762).
Additionally, OpenAFS Rx before version 1.6.14 includes a variable-length padding at the end of the ACK packet, in an attempt to detect the path MTU, but only four octets of the additional padding are initialized (CVE-2015-7763).
