CVSS: 5.9EPSS: 0%CPEs: 10EXPL: 0CVE-2022-4304 – Timing Oracle in RSA Decryption
https://notcve.org/view.php?id=CVE-2022-4304
A timing based side channel exists in the OpenSSL RSA Decryption implementation which could be sufficient to recover a plaintext across a network in a Bleichenbacher style attack. To achieve a successful decryption an attacker would have to be able to send a very large number of trial messages for decryption. The vulnerability affects all RSA padding modes: PKCS#1 v1.5, RSA-OEAP and RSASVE. For example, in a TLS connection, RSA is commonly used by a client to send an encrypted pre-master secret to the server. An attacker that had observed a genuine connection between a client and a server could use this flaw to send trial messages to the server and record the time taken to process them. After a sufficiently large number of messages the attacker could recover the pre-master secret used for the original connection and thus be able to decrypt the application data sent over that connection. • https://security.gentoo.org/glsa/202402-08 https://www.openssl.org/news/secadv/20230207.txt https://access.redhat.com/security/cve/CVE-2022-4304 https://bugzilla.redhat.com/show_bug.cgi?id=2164487 • CWE-203: Observable Discrepancy •
CVSS: 7.4EPSS: 0%CPEs: 9EXPL: 0CVE-2023-0286 – X.400 address type confusion in X.509 GeneralName
https://notcve.org/view.php?id=CVE-2023-0286
There is a type confusion vulnerability relating to X.400 address processing inside an X.509 GeneralName. X.400 addresses were parsed as an ASN1_STRING but the public structure definition for GENERAL_NAME incorrectly specified the type of the x400Address field as ASN1_TYPE. This field is subsequently interpreted by the OpenSSL function GENERAL_NAME_cmp as an ASN1_TYPE rather than an ASN1_STRING. When CRL checking is enabled (i.e. the application sets the X509_V_FLAG_CRL_CHECK flag), this vulnerability may allow an attacker to pass arbitrary pointers to a memcmp call, enabling them to read memory contents or enact a denial of service. In most cases, the attack requires the attacker to provide both the certificate chain and CRL, neither of which need to have a valid signature. If the attacker only controls one of these inputs, the other input must already contain an X.400 address as a CRL distribution point, which is uncommon. • https://ftp.openbsd.org/pub/OpenBSD/LibreSSL/libressl-3.6.2-relnotes.txt https://ftp.openbsd.org/pub/OpenBSD/patches/7.2/common/018_x509.patch.sig https://git.openssl.org/gitweb/?p=openssl.git;a=commitdiff;h=2c6c9d439b484e1ba9830d8454a34fa4f80fdfe9 https://git.openssl.org/gitweb/?p=openssl.git;a=commitdiff;h=2f7530077e0ef79d98718138716bc51ca0cad658 https://git.openssl.org/gitweb/?p=openssl.git;a=commitdiff;h=fd2af07dc083a350c959147097003a14a5e8ac4d https://security.gentoo.org/glsa/202402-08 https://www.open • CWE-704: Incorrect Type Conversion or Cast CWE-843: Access of Resource Using Incompatible Type ('Type Confusion') •
