Out-of-bounds write in the BIOS firmware for some Intel(R) Processors may allow an authenticated user to potentially enable escalation of privilege via local access. Una escritura fuera de límites en el firmware de la BIOS para algunos procesadores Intel(R) puede permitir que un usuario autenticado permita potencialmente una escalada de privilegios por medio de acceso local. • https://security.netapp.com/advisory/ntap-20220930-0004 https://www.intel.com/content/www/us/en/security-center/advisory/intel-sa-00686.html • CWE-787: Out-of-bounds Write •

An issue was discovered in the Linux kernel through 5.18.14. xfrm_expand_policies in net/xfrm/xfrm_policy.c can cause a refcount to be dropped twice. Se ha detectado un problema en el kernel de Linux versiones hasta 5.18.14. la función xfrm_expand_policies en el archivo net/xfrm/xfrm_policy.c puede causar que un refcount sea descartado dos veces A flaw was found in the Linux kernel’s IP framework for transforming packets (XFRM subsystem). An error while resolving policies in xfrm_bundle_lookup causes the refcount to drop twice, leading to a possible crash and a denial of service. • https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit?id=f85daf0e725358be78dfd208dea5fd665d8cb901 https://github.com/torvalds/linux/commit/f85daf0e725358be78dfd208dea5fd665d8cb901 https://lists.debian.org/debian-lts-announce/2022/09/msg00011.html https://lists.debian.org/debian-lts-announce/2022/10/msg00000.html https://security.netapp.com/advisory/ntap-20220901-0007 https://www.debian.org/security/2022/dsa-5207 https://access.redhat.com/security/cve/CVE-2022-36879 https://bugzilla.r • CWE-911: Improper Update of Reference Count •

The OPENSSL_LH_flush() function, which empties a hash table, contains a bug that breaks reuse of the memory occuppied by the removed hash table entries. This function is used when decoding certificates or keys. If a long lived process periodically decodes certificates or keys its memory usage will expand without bounds and the process might be terminated by the operating system causing a denial of service. Also traversing the empty hash table entries will take increasingly more time. Typically such long lived processes might be TLS clients or TLS servers configured to accept client certificate authentication. • https://cert-portal.siemens.com/productcert/pdf/ssa-953464.pdf https://git.openssl.org/gitweb/?p=openssl.git%3Ba=commitdiff%3Bh=64c85430f95200b6b51fe9475bd5203f7c19daf1 https://security.gentoo.org/glsa/202210-02 https://security.netapp.com/advisory/ntap-20220602-0009 https://www.openssl.org/news/secadv/20220503.txt https://access.redhat.com/security/cve/CVE-2022-1473 https://bugzilla.redhat.com/show_bug.cgi?id=2087913 • CWE-401: Missing Release of Memory after Effective Lifetime CWE-459: Incomplete Cleanup •

The function `OCSP_basic_verify` verifies the signer certificate on an OCSP response. In the case where the (non-default) flag OCSP_NOCHECKS is used then the response will be positive (meaning a successful verification) even in the case where the response signing certificate fails to verify. It is anticipated that most users of `OCSP_basic_verify` will not use the OCSP_NOCHECKS flag. In this case the `OCSP_basic_verify` function will return a negative value (indicating a fatal error) in the case of a certificate verification failure. The normal expected return value in this case would be 0. • https://cert-portal.siemens.com/productcert/pdf/ssa-953464.pdf https://git.openssl.org/gitweb/?p=openssl.git%3Ba=commitdiff%3Bh=2eda98790c5c2741d76d23cc1e74b0dc4f4b391a https://security.netapp.com/advisory/ntap-20220602-0009 https://www.openssl.org/news/secadv/20220503.txt https://access.redhat.com/security/cve/CVE-2022-1343 https://bugzilla.redhat.com/show_bug.cgi?id=2087911 • CWE-295: Improper Certificate Validation •

The OpenSSL 3.0 implementation of the RC4-MD5 ciphersuite incorrectly uses the AAD data as the MAC key. This makes the MAC key trivially predictable. An attacker could exploit this issue by performing a man-in-the-middle attack to modify data being sent from one endpoint to an OpenSSL 3.0 recipient such that the modified data would still pass the MAC integrity check. Note that data sent from an OpenSSL 3.0 endpoint to a non-OpenSSL 3.0 endpoint will always be rejected by the recipient and the connection will fail at that point. Many application protocols require data to be sent from the client to the server first. • https://cert-portal.siemens.com/productcert/pdf/ssa-953464.pdf https://git.openssl.org/gitweb/?p=openssl.git%3Ba=commitdiff%3Bh=7d56a74a96828985db7354a55227a511615f732b https://security.netapp.com/advisory/ntap-20220602-0009 https://www.openssl.org/news/secadv/20220503.txt • CWE-327: Use of a Broken or Risky Cryptographic Algorithm •
