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 Xenstore: los invitados pueden dejar ejecutar xenstored sin memoria.

Oxenstored 32->31 bit integer truncation issues Integers in Ocaml are 63 or 31 bits of signed precision. The Ocaml Xenbus library takes a C uint32_t out of the ring and casts it directly to an Ocaml integer. In 64-bit Ocaml builds this is fine, but in 32-bit builds, it truncates off the most significant bit, and then creates unsigned/signed confusion in the remainder. This in turn can feed a negative value into logic not expecting a negative value, resulting in unexpected exceptions being thrown. The unexpected exception is not handled suitably, creating a busy-loop trying (and failing) to take the bad packet out of the xenstore ring. • http://www.openwall.com/lists/oss-security/2022/11/01/10 http://xenbits.xen.org/xsa/advisory-420.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/YTMITQBGC23MSDHUCAPCVGLMVXIBXQTQ https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/YZVXG7OOOXCX6VIPEMLFDPIPUTFAYWPE https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/ZLI2NPNEH7CNJO3VZGQNOI4M4EWLNKPZ https://security.gentoo.org/glsa/202402-07 https:/ • CWE-681: Incorrect Conversion between Numeric Types •

https://notcve.org/view.php?id=CVE-2022-30122
A possible denial of service vulnerability exists in Rack <2.0.9.1, <2.1.4.1 and <2.2.3.1 in the multipart parsing component of Rack. Existe una posible vulnerabilidad de Denegación de Servicio (DoS) en Rack <2.0.9.1, <2.1.4.1 y <2.2.3.1 en el componente de análisis multiparte de Rack. A denial of service flaw was found in ruby-rack. An attacker crafting multipart POST requests can cause Rack's multipart parser to take much longer than expected, leading to a denial of service. • https://discuss.rubyonrails.org/t/cve-2022-30122-denial-of-service-vulnerability-in-rack-multipart-parsing/80729 https://security.gentoo.org/glsa/202310-18 https://security.netapp.com/advisory/ntap-20231208-0012 https://www.debian.org/security/2023/dsa-5530 https://access.redhat.com/security/cve/CVE-2022-30122 https://bugzilla.redhat.com/show_bug.cgi?id=2099519 • CWE-400: Uncontrolled Resource Consumption CWE-770: Allocation of Resources Without Limits or Throttling CWE-1333: Inefficient Regular Expression Complexity •
