python-rsa: decryption of ciphertext leads to DoS

A flaw was found in the python-rsa package, where it does not explicitly check the ciphertext length against the key size and ignores the leading 0 bytes during the decryption of the ciphertext. This flaw allows an attacker to perform a ciphertext attack, leading to a denial of service. The highe...

PT-2020-14094

Name of the Vulnerable Software and Affected Versions jsrsasign versions prior to 8.0.18 Description The issue concerns the RSA PKCS1 v1.5 decryption implementation in the jsrsasign package. It fails to detect ciphertext modification when '0' bytes are prepended to ciphertexts, allowing it to...

Return Of Bleichenbacher's Oracle Threat

ROBOT is the return of a 19-year-old vulnerability that allows performing RSA decryption and signing operations with the private key of a TLS server. Recent assessments: busterb at May 09, 2019 5:57pm UTC reported: The details are pretty heavily documented on robotattack.org, so no need to...

ALPINE-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...

Updated gnutls packages fix security vulnerability

A Bleichenbacher type side-channel based padding oracle attack was found in the way gnutls handles verification of RSA decrypted PKCS1 v1.5 data. An attacker who is able to run process on the same physical core as the victim process, could use this to extract plaintext or in some cases downgrade...

FreeBSD : Mbed TLS -- Local timing attack on RSA decryption (293f40a0-ffa1-11e8-b258-0011d823eebd)

Janos Follath reports : An attacker who can run code on the same machine that is performing an RSA decryption can potentially recover the plaintext through a Bleichenbacher-like oracle. C Tenable Network Security, Inc. The descriptive text and package checks in this plugin were extracted from the...
