SUSE CVE-2019-0223

While investigating bug PROTON-2014, we discovered that under some circumstances Apache Qpid Proton versions 0.9 to 0.27.0 C library and its language bindings can connect to a peer anonymously using TLS even when configured to verify the peer certificate while used with OpenSSL versions before...

SUSE CVE-2019-1543

ChaCha20-Poly1305 is an AEAD cipher, and requires a unique nonce input for every encryption operation. RFC 7539 specifies that the nonce value IV should be 96 bits 12 bytes. OpenSSL allows a variable nonce length and front pads the nonce with 0 bytes if it is less than 12 bytes. However it also...

SUSE CVE-2019-1547

Normally in OpenSSL EC groups always have a co-factor present and this is used in side channel resistant code paths. However, in some cases, it is possible to construct a group using explicit parameters instead of using a named curve. In those cases it is possible that such a group does not have...

SUSE CVE-2019-1549

OpenSSL 1.1.1 introduced a rewritten random number generator RNG. This was intended to include protection in the event of a fork system call in order to ensure that the parent and child processes did not share the same RNG state. However this protection was not being used in the default case. A...

SUSE CVE-2019-1559

If an application encounters a fatal protocol error and then calls SSLshutdown twice once to send a closenotify, and once to receive one then OpenSSL can respond differently to the calling application if a 0 byte record is received with invalid padding compared to if a 0 byte record is received...

SUSE CVE-2019-1551

There is an overflow bug in the x6464 Montgomery squaring procedure used in exponentiation with 512-bit moduli. No EC algorithms are affected. Analysis suggests that attacks against 2-prime RSA1024, 3-prime RSA1536, and DSA1024 as a result of this defect would be very difficult to perform and are...

SUSE CVE-2019-1552

OpenSSL has internal defaults for a directory tree where it can find a configuration file as well as certificates used for verification in TLS. This directory is most commonly referred to as OPENSSLDIR, and is configurable with the --prefix / --openssldir configuration options. For OpenSSL versio...

SUSE CVE-2019-1563

In situations where an attacker receives automated notification of the success or failure of a decryption attempt an attacker, after sending a very large number of messages to be decrypted, can recover a CMS/PKCS7 transported encryption key or decrypt any RSA encrypted message that was encrypted...

SUSE CVE-2019-2390

An unprivileged user or program on Microsoft Windows which can create OpenSSL configuration files in a fixed location may cause utility programs shipped with MongoDB server to run attacker defined code as the user running the utility. This issue MongoDB Server v4.0 versions prior to 4.0.11; Mongo...

SUSE CVE-2019-5443

A non-privileged user or program can put code and a config file in a known non-privileged path under C:/usr/local/ that will make curl = 7.65.1 automatically run the code as an openssl "engine" on invocation. If that curl is invoked by a privileged user it can do anything it wants...

SUSE CVE-2019-17185

In FreeRADIUS 3.0.x before 3.0.20, the EAP-pwd module used a global OpenSSL BNCTX instance to handle all handshakes. This mean multiple threads use the same BNCTX instance concurrently, resulting in crashes when concurrent EAP-pwd handshakes are initiated. This can be abused by an adversary as a...

SUSE CVE-2020-1967

Server or client applications that call the SSLcheckchain function during or after a TLS 1.3 handshake may crash due to a NULL pointer dereference as a result of incorrect handling of the "signaturealgorithmscert" TLS extension. The crash occurs if an invalid or unrecognised signature algorithm i...

SUSE CVE-2020-1971

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. This function behaves incorrect...

SUSE CVE-2020-1968

The Raccoon attack exploits a flaw in the TLS specification which can lead to an attacker being able to compute the pre-master secret in connections which have used a Diffie-Hellman DH based ciphersuite. In such a case this would result in the attacker being able to eavesdrop on all encrypted...

SUSE CVE-2020-7043

An issue was discovered in openfortivpn 1.11.0 when used with OpenSSL before 1.0.2. tunnel.c mishandles certificate validation because hostname comparisons do not consider '\0' characters, as demonstrated by a good.example.com\x00evil.example.com attack...

SUSE CVE-2020-7069

In PHP versions 7.2.x below 7.2.34, 7.3.x below 7.3.23 and 7.4.x below 7.4.11, when AES-CCM mode is used with opensslencrypt function with 12 bytes IV, only first 7 bytes of the IV is actually used. This can lead to both decreased security and incorrect encryption data...

SUSE CVE-2020-13962

Qt 5.12.2 through 5.14.2, as used in unofficial builds of Mumble 1.3.0 and other products, mishandles OpenSSL's error queue, which can cause a denial of service to QSslSocket users. Because errors leak in unrelated TLS sessions, an unrelated session may be disconnected when any handshake fails...

SUSE CVE-2020-14396

An issue was discovered in LibVNCServer before 0.9.13. libvncclient/tlsopenssl.c has a NULL pointer dereference...

SUSE CVE-2020-28018

Exim 4 before 4.94.2 allows Use After Free in smtpreset in certain situations that may be common for builds with OpenSSL...

SUSE CVE-2021-3446

A flaw was found in libtpms in versions before 0.8.2. The commonly used integration of libtpms with OpenSSL contained a vulnerability related to the returned IV initialization vector when certain symmetric ciphers were used. Instead of returning the last IV it returned the initial IV to the calle...
