Security Advisory Description The OpenSSL RSA Key generation algorithm has been shown to be vulnerable to a cache timing side channel attack. An attacker with sufficient access to mount cache timing attacks during the RSA key generation process could recover the private key. Fixed in OpenSSL...

K30215094: Ruby vulnerability CVE-2016-7798

Security Advisory Description The openssl gem for Ruby uses the same initialization vector IV in GCM Mode aes--gcm when the IV is set before the key, which makes it easier for context-dependent attackers to bypass the encryption protection mechanism. CVE-2016-7798 Impact There is no impact; F5...

K42910051: OpenSSL vulnerability CVE-2020-1971

Security Advisory Description The X.509 GeneralName type is a generic type for representing different types of names. One of those name types is known as EDIPartyName. OpenSSL provides a function GENERALNAMEcmp which compares different instances of a GENERALNAME to see if they are equal or not...

K16321: OpenSSL vulnerability CVE-2015-0293

Security Advisory Description The SSLv2 implementation 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 allows remote attackers to cause a denial of service s2lib.c assertion failure and daemon exit via a crafted CLIENT-MASTER-KEY message. CVE-2015-0293...

K16319: OpenSSL vulnerability CVE-2015-0288

Security Advisory Description Description The X509toX509REQ function in crypto/x509/x509req.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 might allow attackers to cause a denial of service NULL pointer dereference and application crash via an inval...

K16317: OpenSSL vulnerability CVE-2015-0286

Security Advisory Description The ASN1TYPEcmp function in crypto/asn1/atype.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 properly perform Boolean-type comparisons, which allows remote attackers to cause a denial of service invalid read...

K15551553: OpenSSL vulnerability CVE-2017-3730

Security Advisory Description In OpenSSL 1.1.0 before 1.1.0d, if a malicious server supplies bad parameters for a DHE or ECDHE key exchange then this can result in the client attempting to dereference a NULL pointer leading to a client crash. This could be exploited in a Denial of Service attack...

K53084033: OpenSSL vulnerability CVE-2016-2178

Security Advisory Description The dsasignsetup function in crypto/dsa/dsaossl.c in OpenSSL through 1.0.2h does not properly ensure the use of constant-time operations, which makes it easier for local users to discover a DSA private key via a timing side-channel attack. CVE-2016-2178 Impact An...

K62695363: OpenSSL vulnerability CVE-2018-0733

Security Advisory Description Because of an implementation bug the PA-RISC CRYPTOmemcmp function is effectively reduced to only comparing the least significant bit of each byte. This allows an attacker to forge messages that would be considered as authenticated in an amount of tries lower than th...
