https://notcve.org/view.php?id=CVE-2022-30594
The Linux kernel before 5.17.2 mishandles seccomp permissions. The PTRACE_SEIZE code path allows attackers to bypass intended restrictions on setting the PT_SUSPEND_SECCOMP flag. El kernel de Linux versiones anteriores a 5.17.2, maneja inapropiadamente los permisos de seccomp. La ruta de código PTRACE_SEIZE permite a atacantes omitir las restricciones previstas al establecer el flag PT_SUSPEND_SECCOMP A flaw was found in the Linux kernel. The PTRACE_SEIZE code path allows attackers to bypass intended restrictions on setting the PT_SUSPEND_SECCOMP flag, possibly disabling seccomp. • http://packetstormsecurity.com/files/167386/Kernel-Live-Patch-Security-Notice-LSN-0086-1.html http://packetstormsecurity.com/files/170362/Linux-PT_SUSPEND_SECCOMP-Permission-Bypass-Ptracer-Death-Race.html https://bugs.chromium.org/p/project-zero/issues/detail?id=2276 https://cdn.kernel.org/pub/linux/kernel/v5.x/ChangeLog-5.17.2 https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=ee1fee900537b5d9560e9f937402de5ddc8412f3 https://github.com/torvalds/linux/commit/ee1fee900537b5d9560e9f937402de • CWE-276: Incorrect Default Permissions CWE-862: Missing Authorization •
CVSS: 5.9EPSS: 0%CPEs: 43EXPL: 0CVE-2022-1434 – Incorrect MAC key used in the RC4-MD5 ciphersuite
https://notcve.org/view.php?id=CVE-2022-1434
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 •
CVSS: 10.0EPSS: 10%CPEs: 59EXPL: 5CVE-2022-1292 – The c_rehash script allows command injection
https://notcve.org/view.php?id=CVE-2022-1292
The c_rehash script does not properly sanitise shell metacharacters to prevent command injection. 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. Fixed in OpenSSL 3.0.3 (Affected 3.0.0,3.0.1,3.0.2). • https://github.com/alcaparra/CVE-2022-1292 https://github.com/li8u99/CVE-2022-1292 https://github.com/greek0x0/CVE-2022-1292 https://github.com/rama291041610/CVE-2022-1292 https://github.com/und3sc0n0c1d0/CVE-2022-1292 https://cert-portal.siemens.com/productcert/pdf/ssa-953464.pdf https://git.openssl.org/gitweb/?p=openssl.git%3Ba=commitdiff%3Bh=1ad73b4d27bd8c1b369a3cd453681d3a4f1bb9b2 https://git.openssl.org/gitweb/?p=openssl.git%3Ba=commitdiff%3Bh=548d3f280a6e737673f5b61fce24bb100108dfeb https://git • 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') •
CVSS: 5.3EPSS: 0%CPEs: 43EXPL: 0CVE-2022-1343 – OCSP_basic_verify may incorrectly verify the response signing certificate
https://notcve.org/view.php?id=CVE-2022-1343
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 •
CVSS: 7.5EPSS: 0%CPEs: 43EXPL: 0CVE-2022-1473 – Resource leakage when decoding certificates and keys
https://notcve.org/view.php?id=CVE-2022-1473
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 •
