Scientific Linux Security Update : openafs on SL5.x, SL6.x i386/x86_64 (20140411)

medium Nessus Plugin ID 73454

Synopsis

The remote Scientific Linux host is missing one or more security updates.

Description

An attacker with the ability to connect to an OpenAFS fileserver can trigger a buffer overflow, crashing the server.

The GetStatistics64 remote procedure call (RPC) was introduced in OpenAFS 1.4.8 as part of the support for fileserver partitions larger than 2 TiB. The GetStatistics64 RPC is used by remote administrative programs to retrieve statistical information about fileservers. The GetStatistics64 RPC requests do not require authentication.

A bug has been discovered in the GetStatistics64 RPC which can trigger a fileserver crash. The version argument of the GetStatistics64 RPC is used to determine how much memory is allocated for the RPC reply.
However the range of this argument is not validated, allowing an attacker to cause insufficient memory to be allocated for the statistical information reply buffer.

Clients are not affected.

Solution

Update the affected packages.
