UBUNTU-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...
openssl: timing side channel attack in the DSA signature algorithm
The OpenSSL DSA signature algorithm has been shown to be vulnerable to a timing side channel attack. An attacker could use variations in the signing algorithm to recover the private key. Fixed in OpenSSL 1.1.1a Affected 1.1.1. Fixed in OpenSSL 1.1.0j Affected 1.1.0-1.1.0i. Fixed in OpenSSL 1.0.2q...
UBUNTU-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...
openssl: Handling of crafted recursive ASN.1 structures can cause a stack overflow and resulting denial of service
Constructed ASN.1 types with a recursive definition such as can be found in PKCS7 could eventually exceed the stack given malicious input with excessive recursion. This could result in a Denial Of Service attack. There are no such structures used within SSL/TLS that come from untrusted sources so...
openssl: Malicious server can send large prime to client during DH(E) TLS handshake causing the client to hang
During key agreement in a TLS handshake using a DHE based ciphersuite a malicious server can send a very large prime value to the client. This will cause the client to spend an unreasonably long period of time generating a key for this prime resulting in a hang until the client has finished. This...
DEBIAN-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...

openssl: rsaz_1024_mul_avx2 overflow bug on x86_64
There is an overflow bug in the AVX2 Montgomery multiplication procedure used in exponentiation with 1024-bit moduli. No EC algorithms are affected. Analysis suggests that attacks against RSA and DSA as a result of this defect would be very difficult to perform and are not believed likely. Attack...
Security Bulletin: Tivoli Management Framework is affected by vulnerabilities in OpenSSL (CVE-2014-0160 and CVE-2014-0076)
Summary Security vulnerabilities have been discovered in OpenSSL. Vulnerability Details CVE-ID: CVE-2014-0160 DESCRIPTION: OpenSSL could allow a remote attacker to obtain sensitive information, caused by an error in the TLS/DTLS heartbeat functionality. An attacker could exploit this vulnerabilit...

DEBIAN-CVE-2018-0733
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 that guaranteed by the security...
