MGASA-2020-0023 Updated openssl packages fix security vulnerability
Updated compat-openssl10 and openssl packages fix security vulnerability: 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...
Integer Overflow
OpenSSL is vulnerable to integer overflows. It exists due to a mishandling of overflow in rsaz512sqr for the x6464 Montgomery squaring procedure used in exponentiation with 512-bit moduli...
Buffer overflow
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...
CVE-2019-1551
CVE-2019-1551 refers to an overflow bug in the x64_64 Montgomery squaring procedure used in OpenSSL during exponentiation with 512-bit moduli. OpenSSL notes no impact to EC, while DH512 attacks are only just feasible under certain conditions. Public disclosures and advisories confirm the issue an...
DEBIAN-CVE-2015-0837
The mpipowm function in Libgcrypt before 1.6.3 and GnuPG before 1.4.19 allows attackers to obtain sensitive information by leveraging timing differences when accessing a pre-computed table during modular exponentiation, related to a "Last-Level Cache Side-Channel Attack."...

OpenSSL 1.1.0 < 1.1.0h Multiple Vulnerabilities
The version of OpenSSL installed on the remote host is prior to 1.1.0h. It is, therefore, affected by multiple vulnerabilities as referenced in the 1.1.0h advisory. - Constructed ASN.1 types with a recursive definition such as can be found in PKCS7 could eventually exceed the stack given maliciou...

CVE-2017-3738
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...

Updated botan packages fix security vulnerability
In the Montgomery exponentiation code, a table of precomputed values is used. An attacker able to analyze which cache lines were accessed perhaps via an active attack such as Prime+Probe could recover information about the exponent CVE-2017-14737...

Libgcrypt Attack Allowed Recovery of RSA-1024 Keys
The cryptographic library Libgcrypt is vulnerable to a local side-channel attack; something researchers warn could allow full key recovery for RSA-1024. The vulnerability CVE-2017-7526 is tied to the fact that Libgcrypt, which is based on code from GnuPG, uses left to right sliding windows...
Side Channel Attack On Modular Exponentiation
OpenSSL is vulnerable to side channel attacks. The vulnerability exploits cache-bank conflicts on the Intel Sandy-Bridge microarchitecture, exposing RSA keys. However, an attacker can only exploit this only if he has control of code in a thread running on the same hyper-threaded core as the victi...
