Updated python-rsa packages fix security vulnerability

Python-RSA before 4.1 ignores leading '\0' bytes during decryption of ciphertext. This could conceivably have a security-relevant impact, e.g., by helping an attacker to infer that an application uses Python-RSA, or if the length of accepted ciphertext affects application behavior such as by...

Name of the Vulnerable Software and Affected Versions: Python-RSA versions prior to 4.1 Description: The issue concerns the decryption of ciphertext, where leading '0' bytes are ignored. This could potentially have security implications, such as helping an attacker infer that an application uses...

Shadowsocks-libev ss-server Stream Cipher Information Disclosure Vulnerability

Summary An exploitable information disclosure vulnerability exists in the network packet handling functionality of Shadowsocks-libev 3.3.2. When utilizing a Stream Cipher, a specially crafted set of network packets can cause an outbound connection from the server, resulting in information...

On Padding Oracle Attacks

Poodle is a vulnerability found in late 2014, and it is still occasionally seen during penetration tests. The vulnerability allows an attacker with a man-in-the-middle position to downgrade a secure connection between a client and a server to the vulnerable SSLv3. After the connection is...

Unisys ClearPath MCP System TCP/IP networking Module Bot Attack Vulnerability

Unisys ClearPath MCP system is a set of operating systems dedicated to ClearPath servers from Unisys Corporation in the U.S. TCP/IP networking is one of the network connection modules. A security vulnerability exists in the TLS implementation of the TCP/IP networking module versions 58.1, 59.1, a...

CVE-2017-17428

Cavium Nitrox SSL, Nitrox V SSL, and TurboSSL software development kits SDKs allow remote attackers to decrypt TLS ciphertext data by leveraging a Bleichenbacher RSA padding oracle, aka a ROBOT attack...

CVE-2018-5762: Undefined Security Weakness

The TLS implementation in the TCP/IP networking module in Unisys ClearPath MCP systems with TCP-IP-SW 58.1 before 58.160, 59.1 before 059.1a.17 IC 17, and 60.0 before 60.044 might allow remote attackers to decrypt TLS ciphertext data by leveraging a Bleichenbacher RSA padding oracle, aka a ROBOT...

SSL/TLS: Cross-protocol attack on TLS using SSLv2 (DROWN)

A padding oracle flaw was found in the Secure Sockets Layer version 2.0 SSLv2 protocol. An attacker could potentially use this flaw to decrypt RSA-encrypted cipher text from a connection using a newer SSL/TLS protocol version, allowing them to decrypt such connections. This cross-protocol attack ...

CVE-2016-0704: Exposure of Sensitive Information to an Unauthorized Actor

An oracle protection mechanism in the getclientmasterkey function in s2srvr.c in the SSLv2 implementation in OpenSSL before 0.9.8zf, 1.0.0 before 1.0.0r, 1.0.1 before 1.0.1m, and 1.0.2 before 1.0.2a overwrites incorrect MASTER-KEY bytes during use of export cipher suites, which makes it easier fo...

CVE-2016-0703: Exposure of Sensitive Information to an Unauthorized Actor

The getclientmasterkey function in s2srvr.c in the SSLv2 implementation in OpenSSL before 0.9.8zf, 1.0.0 before 1.0.0r, 1.0.1 before 1.0.1m, and 1.0.2 before 1.0.2a accepts a nonzero CLIENT-MASTER-KEY CLEAR-KEY-LENGTH value for an arbitrary cipher, which allows man-in-the-middle attackers to...

CVE-2016-0800: Exposure of Sensitive Information to an Unauthorized Actor

The SSLv2 protocol, as used in OpenSSL before 1.0.1s and 1.0.2 before 1.0.2g and other products, requires a server to send a ServerVerify message before establishing that a client possesses certain plaintext RSA data, which makes it easier for remote attackers to decrypt TLS ciphertext data by...

SSL/TLS: Padding Oracle On Downgraded Legacy Encryption attack

A flaw was found in the way SSL 3.0 handled padding bytes when decrypting messages encrypted using block ciphers in cipher block chaining CBC mode. This flaw allows a man-in-the-middle MITM attacker to decrypt a selected byte of a cipher text in as few as 256 tries if they are able to force a...
