openssl: Generating excessively long X9.42 DH keys or checking excessively long X9.42 DH keys or parameters may be very slow

A flaw was found in OpenSSL, which caused the generation or checking of long X9.42 DH keys or parameters to be much slower than expected. This issue could lead to a denial of service...

openssl: Generating excessively long X9.42 DH keys or checking excessively long X9.42 DH keys or parameters may be very slow

A flaw was found in OpenSSL, which caused the generation or checking of long X9.42 DH keys or parameters to be much slower than expected. This issue could lead to a denial of service...

Medium: openssl

Issue Overview: A flaw was found in OpenSSL. When the EVPPKEYpubliccheck function is called in 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, i...

openssl: Incorrect cipher key and IV length processing

A flaw was found in OpenSSL in how it processes key and initialization vector IV lengths. This issue can lead to potential truncation or overruns during the initialization of some symmetric ciphers. A truncation in the IV can result in non-uniqueness, which could result in loss of confidentiality...

openssl: Possible DoS translating ASN.1 object identifiers

A flaw was found in OpenSSL resulting in a possible denial of service while translating ASN.1 object identifiers. Applications that use OBJobj2txt directly, or use any of the OpenSSL subsystems OCSP, PKCS7/SMIME, CMS, CMP/CRMF or TS with no message size limit may experience long delays when...

openssl: Invalid certificate policies in leaf certificates are silently ignored

A flaw was found in OpenSSL. Applications that use a non-default option when verifying certificates may be vulnerable to an attack from a malicious CA to circumvent certain checks. OpenSSL and other certificate policy checks silently ignore invalid certificate policies in leaf certificates that a...

openssl: c_rehash script allows command injection

A flaw was found in OpenSSL. The crehash script does not properly sanitize shell meta-characters to prevent command injection. Some operating systems distribute this script in a manner where it is automatically executed. This flaw allows an attacker to execute arbitrary commands with the privileg...

openssl: Using a Custom Cipher with NID_undef may lead to NULL encryption

A flaw was found in OpenSSL, where it incorrectly handles legacy custom ciphers passed to the EVPEncryptInitex2, EVPDecryptInitex2 and EVPCipherInitex2 functions as well as other similarly named encryption and decryption initialization functions. Instead of using the custom cipher directly, it...

Important: openssl

Issue Overview: A flaw was found in Open SSL. A read buffer overrun can be triggered in X.509 certificate verification, specifically in name constraint checking. Note that this occurs after certificate chain signature verification, and requires either a CA to have signed the malicious certificate...

SUSE CVE-2014-0224

OpenSSL before 0.9.8za, 1.0.0 before 1.0.0m, and 1.0.1 before 1.0.1h does not properly restrict processing of ChangeCipherSpec messages, which allows man-in-the-middle attackers to trigger use of a zero-length master key in certain OpenSSL-to-OpenSSL communications, and consequently hijack sessio...

SUSE CVE-2015-0287

The ASN1itemexd2i function in crypto/asn1/tasndec.c in OpenSSL before 0.9.8zf, 1.0.0 before 1.0.0r, 1.0.1 before 1.0.1m, and 1.0.2 before 1.0.2a does not reinitialize CHOICE and ADB data structures, which might allow attackers to cause a denial of service invalid write operation and memory...

SUSE CVE-2015-0291

The sigalgs implementation in t1lib.c in OpenSSL 1.0.2 before 1.0.2a allows remote attackers to cause a denial of service NULL pointer dereference and daemon crash by using an invalid signaturealgorithms extension in the ClientHello message during a renegotiation...

openssl: the c_rehash script allows command injection

A flaw was found in OpenSSL. The issue in CVE-2022-1292 did not find other places in the crehash script where it possibly passed the file names of certificates being hashed to a command executed through the shell. Some operating systems distribute this script in a manner where it is automatically...

openssl: OPENSSL_LH_flush() breaks reuse of memory

A memory leak flaw was found in OpenSSL, resulting in TLS servers and clients being halted by out-of-memory conditions, leading to a denial of service. An attacker needs to repeat actions continuously to trigger this vulnerability, resulting in a loss of application availability...

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...

openssl: Infinite loop in BN_mod_sqrt() reachable when parsing certificates

A flaw was found in OpenSSL. It is possible to trigger an infinite loop by crafting a certificate that has invalid elliptic curve parameters. Since certificate parsing happens before verification of the certificate signature, any process that parses an externally supplied certificate may be subje...
