The issue affects the cache manager in the client, allowing remote attackers to cause a denial of service, potentially leading to disruption of confidentiality, integrity, and availability of protected information. The exploitation can be done remotely, related to the use of the ERR PTR macro when handling an RX response with a large error-code value that is interpreted as a pointer and dereferenced.

The issue is related to a heap-based buffer overflow in the cache manager of the client in OpenAFS, which can be exploited by remote attackers. This can be achieved by sending an RX response containing more data than specified in a request, potentially leading to a denial of service or the execution of arbitrary code. The vulnerability is associated with the use of XDR arrays. Multiple vulnerabilities in the OpenAFS package can lead to breaches of confidentiality, integrity, and availability of protected information, and these vulnerabilities can be exploited remotely.
