nss: Memory corruption in decodeECorDsaSignature with DSA signatures (and RSA-PSS)

A remote code execution flaw was found in the way NSS verifies certificates. This flaw allows an attacker posing as an SSL/TLS server to trigger this issue in a client application compiled with NSS when it tries to initiate an SSL/TLS connection. Similarly, a server application compiled with NSS,...

UBUNTU-CVE-2021-43527

NSS Network Security Services versions prior to 3.73 or 3.68.1 ESR are vulnerable to a heap overflow when handling DER-encoded DSA or RSA-PSS signatures. Applications using NSS for handling signatures encoded within CMS, S/MIME, PKCS \7, or PKCS \12 are likely to be impacted. Applications using N...

thunderbird: Memory corruption when processing S/MIME messages

A flaw was found in Thunderbird, which is vulnerable to the heap overflow described in CVE-2021-43527 when processing S/MIME messages. Thunderbird versions 91.3.0 and later will not call the vulnerable code when processing S/MIME messages that contain certificates with DER-encoded DSA or RSA-PSS...

nettle: Out of bounds memory access in signature verification

A flaw was found in Nettle, where several Nettle signature verification functions GOST DSA, EDDSA & ECDSA result in the Elliptic Curve Cryptography point ECC multiply function being called with out-of-range scalers, possibly resulting in incorrect results. This flaw allows an attacker to force an...

Dell RSA BSAFE Crypto-J Information Disclosure Vulnerability

Dell RSA BSAFE Crypto-J is RSA's FIPS-validated Java cryptographic module. Dell RSA BSAFE Crypto-J versions prior to 6.2.5 are vulnerable to an information disclosure vulnerability during DSA key generation. An attacker could exploit this vulnerability to recover the DSA key...

CVE-2019-3740

RSA BSAFE Crypto-J versions prior to 6.2.5 are vulnerable to an Information Exposure Through Timing Discrepancy vulnerabilities during DSA key generation. A malicious remote attacker could potentially exploit those vulnerabilities to recover DSA keys...

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...

The vulnerability of the implementation of the Digital Signature Algorithm (DSA) in the OpenSSL library allows a perpetrator to gain unauthorized access to protected information.

The vulnerability of the Digital Signature Algorithm implementation in the OpenSSL library is related to errors in managing cryptographic keys. Exploiting this vulnerability could allow an attacker, operating remotely, to gain unauthorized access to protected information by recovering the secret...

OpenSSL: Double-free in DSA code

A double-free flaw was found in the way OpenSSL parsed certain malformed DSA Digital Signature Algorithm private keys. An attacker could create specially crafted DSA private keys that, when processed by an application compiled against OpenSSL, could cause the application to crash...
