https://notcve.org/view.php?id=CVE-2022-2318
There are use-after-free vulnerabilities caused by timer handler in net/rose/rose_timer.c of linux that allow attackers to crash linux kernel without any privileges. Se presentan vulnerabilidades de uso de memoria previamente liberada causadas por el manejador del temporizador en el archivo net/rose/rose_timer.c de linux que permiten a atacantes bloquear el kernel de linux sin ningún privilegio • https://github.com/torvalds/linux/commit/9cc02ede696272c5271a401e4f27c262359bc2f6 https://lists.debian.org/debian-lts-announce/2022/10/msg00000.html https://security.netapp.com/advisory/ntap-20230120-0001 https://www.debian.org/security/2022/dsa-5191 • CWE-416: Use After Free •
CVE-2022-2097 – AES OCB fails to encrypt some bytes
https://notcve.org/view.php?id=CVE-2022-2097
AES OCB mode for 32-bit x86 platforms using the AES-NI assembly optimised implementation will not encrypt the entirety of the data under some circumstances. This could reveal sixteen bytes of data that was preexisting in the memory that wasn't written. In the special case of "in place" encryption, sixteen bytes of the plaintext would be revealed. Since OpenSSL does not support OCB based cipher suites for TLS and DTLS, they are both unaffected. Fixed in OpenSSL 3.0.5 (Affected 3.0.0-3.0.4). • https://cert-portal.siemens.com/productcert/pdf/ssa-332410.pdf https://git.openssl.org/gitweb/?p=openssl.git%3Ba=commitdiff%3Bh=919925673d6c9cfed3c1085497f5dfbbed5fc431 https://git.openssl.org/gitweb/?p=openssl.git%3Ba=commitdiff%3Bh=a98f339ddd7e8f487d6e0088d4a9a42324885a93 https://lists.debian.org/debian-lts-announce/2023/02/msg00019.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/R6CK57NBQFTPUMXAPJURCGXUYT76NQAK https://lists.fedoraproject.org/archives/list/package-announce%40lists.fe • CWE-325: Missing Cryptographic Step CWE-327: Use of a Broken or Risky Cryptographic Algorithm •
CVE-2022-34918 – kernel: heap overflow in nft_set_elem_init()
https://notcve.org/view.php?id=CVE-2022-34918
An issue was discovered in the Linux kernel through 5.18.9. A type confusion bug in nft_set_elem_init (leading to a buffer overflow) could be used by a local attacker to escalate privileges, a different vulnerability than CVE-2022-32250. (The attacker can obtain root access, but must start with an unprivileged user namespace to obtain CAP_NET_ADMIN access.) This can be fixed in nft_setelem_parse_data in net/netfilter/nf_tables_api.c. Se ha detectado un problema en el kernel de Linux versiones hasta 5.18.9. • https://github.com/veritas501/CVE-2022-34918 https://github.com/randorisec/CVE-2022-34918-LPE-PoC https://github.com/merlinepedra25/CVE-2022-34918-LPE-PoC https://github.com/merlinepedra/CVE-2022-34918-LPE-PoC https://github.com/linulinu/CVE-2022-34918 http://packetstormsecurity.com/files/168191/Kernel-Live-Patch-Security-Notice-LSN-0089-1.html http://packetstormsecurity.com/files/168543/Netfilter-nft_set_elem_init-Heap-Overflow-Privilege-Escalation.html http://www.openwall.com/lists/oss-secur • CWE-843: Access of Resource Using Incompatible Type ('Type Confusion') CWE-1025: Comparison Using Wrong Factors •
CVE-2022-2274 – RSA implementation bug in AVX512IFMA instructions
https://notcve.org/view.php?id=CVE-2022-2274
The OpenSSL 3.0.4 release introduced a serious bug in the RSA implementation for X86_64 CPUs supporting the AVX512IFMA instructions. This issue makes the RSA implementation with 2048 bit private keys incorrect on such machines and memory corruption will happen during the computation. As a consequence of the memory corruption an attacker may be able to trigger a remote code execution on the machine performing the computation. SSL/TLS servers or other servers using 2048 bit RSA private keys running on machines supporting AVX512IFMA instructions of the X86_64 architecture are affected by this issue. OpenSSL versión 3.0.4, introdujo un grave error en la implementación de RSA para CPUs X86_64 que soportan las instrucciones AVX512IFMA. • https://github.com/Malwareman007/CVE-2022-2274 https://github.com/DesmondSanctity/CVE-2022-2274 https://git.openssl.org/gitweb/?p=openssl.git%3Ba=commitdiff%3Bh=4d8a88c134df634ba610ff8db1eb8478ac5fd345 https://github.com/openssl/openssl/issues/18625 https://security.netapp.com/advisory/ntap-20220715-0010 https://www.openssl.org/news/secadv/20220705.txt • CWE-787: Out-of-bounds Write •
CVE-2022-2068 – The c_rehash script allows command injection
https://notcve.org/view.php?id=CVE-2022-2068
In addition to the c_rehash shell command injection identified in CVE-2022-1292, further circumstances where the c_rehash script does not properly sanitise shell metacharacters to prevent command injection were found by code review. When the CVE-2022-1292 was fixed it was not discovered that there are other places in the script where the file names of certificates being hashed were possibly passed to a command executed through the shell. This script is distributed by some operating systems in a manner where it is automatically executed. On such operating systems, an attacker could execute arbitrary commands with the privileges of the script. Use of the c_rehash script is considered obsolete and should be replaced by the OpenSSL rehash command line tool. • https://cert-portal.siemens.com/productcert/pdf/ssa-332410.pdf https://git.openssl.org/gitweb/?p=openssl.git%3Ba=commitdiff%3Bh=2c9c35870601b4a44d86ddbf512b38df38285cfa https://git.openssl.org/gitweb/?p=openssl.git%3Ba=commitdiff%3Bh=7a9c027159fe9e1bbc2cd38a8a2914bff0d5abd9 https://git.openssl.org/gitweb/?p=openssl.git%3Ba=commitdiff%3Bh=9639817dac8bbbaa64d09efad7464ccc405527c7 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/6WZZBKUHQFGSKGNXXKICSRPL7AMVW5M5 https://lists.fedoraproject.org/archives/list • CWE-77: Improper Neutralization of Special Elements used in a Command ('Command Injection') CWE-78: Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') •
