Multiple vulnerabilities has been found and corrected in openafs: The cache manager in the client in OpenAFS 1.0 through 1.4.8 and 1.5.0 through 1.5.58 on Linux allows remote attackers to cause a denial of service via an RX response with a large error-code value that is interpreted as a pointer and dereferenced, related to use of the ERR_PTR macro . Heap-based buffer overflow in the cache manager in the client in OpenAFS 1.0 through 1.4.8 and 1.5.0 through 1.5.58 on Unix platforms allows remote attackers to cause a denial of service or possibly execute arbitrary code via an RX response containing more data than specified in a request, related to use of XDR arrays . The updated packages have been patched to correct these issues.
