CVSS: 5.9EPSS: 0%CPEs: 3EXPL: 0CVE-2023-6237 – Excessive time spent checking invalid RSA public keys
https://notcve.org/view.php?id=CVE-2023-6237
Issue summary: Checking excessively long invalid RSA public keys may take a long time. Impact summary: Applications that use the function EVP_PKEY_public_check() to check RSA public keys may experience long delays. Where the key that is being checked has been obtained from an untrusted source this may lead to a Denial of Service. When function EVP_PKEY_public_check() is called on RSA public keys, a computation is done to confirm that the RSA modulus, n, is composite. For valid RSA keys, n is a product of two or more large primes and this computation completes quickly. However, if n is an overly large prime, then this computation would take a long time. An application that calls EVP_PKEY_public_check() and supplies an RSA key obtained from an untrusted source could be vulnerable to a Denial of Service attack. The function EVP_PKEY_public_check() is not called from other OpenSSL functions however it is called from the OpenSSL pkey command line application. For that reason that application is also vulnerable if used with the '-pubin' and '-check' options on untrusted data. The OpenSSL SSL/TLS implementation is not affected by this issue. The OpenSSL 3.0 and 3.1 FIPS providers are affected by this issue. Resumen del problema: la comprobación de claves públicas RSA inválidas excesivamente largas puede llevar mucho tiempo. • http://www.openwall.com/lists/oss-security/2024/03/11/1 https://github.com/openssl/openssl/commit/0b0f7abfb37350794a4b8960fafc292cd5d1b84d https://github.com/openssl/openssl/commit/18c02492138d1eb8b6548cb26e7b625fb2414a2a https://github.com/openssl/openssl/commit/a830f551557d3d66a84bbb18a5b889c640c36294 https://security.netapp.com/advisory/ntap-20240531-0007 https://www.openssl.org/news/secadv/20240115.txt https://access.redhat.com/security/cve/CVE-2023-6237 https://bugzilla.redhat.com/show_bug.cgi?id=2258502 • CWE-400: Uncontrolled Resource Consumption •
CVSS: 6.5EPSS: 0%CPEs: 3EXPL: 0CVE-2023-6129 – POLY1305 MAC implementation corrupts vector registers on PowerPC
https://notcve.org/view.php?id=CVE-2023-6129
Issue summary: The POLY1305 MAC (message authentication code) implementation contains a bug that might corrupt the internal state of applications running on PowerPC CPU based platforms if the CPU provides vector instructions. Impact summary: If an attacker can influence whether the POLY1305 MAC algorithm is used, the application state might be corrupted with various application dependent consequences. The POLY1305 MAC (message authentication code) implementation in OpenSSL for PowerPC CPUs restores the contents of vector registers in a different order than they are saved. Thus the contents of some of these vector registers are corrupted when returning to the caller. The vulnerable code is used only on newer PowerPC processors supporting the PowerISA 2.07 instructions. The consequences of this kind of internal application state corruption can be various - from no consequences, if the calling application does not depend on the contents of non-volatile XMM registers at all, to the worst consequences, where the attacker could get complete control of the application process. However unless the compiler uses the vector registers for storing pointers, the most likely consequence, if any, would be an incorrect result of some application dependent calculations or a crash leading to a denial of service. The POLY1305 MAC algorithm is most frequently used as part of the CHACHA20-POLY1305 AEAD (authenticated encryption with associated data) algorithm. The most common usage of this AEAD cipher is with TLS protocol versions 1.2 and 1.3. • http://www.openwall.com/lists/oss-security/2024/03/11/1 https://github.com/openssl/openssl/commit/050d26383d4e264966fb83428e72d5d48f402d35 https://github.com/openssl/openssl/commit/5b139f95c9a47a55a0c54100f3837b1eee942b04 https://github.com/openssl/openssl/commit/f3fc5808fe9ff74042d639839610d03b8fdcc015 https://security.netapp.com/advisory/ntap-20240216-0009 https://security.netapp.com/advisory/ntap-20240426-0008 https://security.netapp.com/advisory/ntap-20240426-0013 https://security.netapp.com/advisory/ntap-20240503-0011 https: • CWE-328: Use of Weak Hash CWE-787: Out-of-bounds Write •
