Description
Xenstore: guests can let run xenstored out of memory T[his CNA information record relates to multiple CVEs; the text explains which aspects/vulnerabilities correspond to which CVE.] Malicious guests can cause xenstored to allocate vast amounts of memory, eventually resulting in a Denial of Service (DoS) of xenstored. There are multiple ways how guests can cause large memory allocations in xenstored: – – by issuing new requests to xenstored without reading the responses, causing the responses to be buffered in memory – – by causing large number of watch events to be generated via setting up multiple xenstore watches and then e.g. deleting many xenstore nodes below the watched path – – by creating as many nodes as allowed with the maximum allowed size and path length in as many transactions as possible – – by accessing many nodes inside a transaction
