OpenSSL: Race condition handling PSK identify hint

A race condition flaw, leading to a double free, was found in the way OpenSSL handled pre-shared key PSK identify hints. A remote attacker could use this flaw to crash a multi-threaded SSL/TLS client using OpenSSL...

curl: Re-using connection with wrong client cert

It was found that the libcurl library did not check the client certificate when choosing the TLS connection to reuse. An attacker could potentially use this flaw to hijack the authentication of the connection by leveraging a previously created connection with a different client certificate...

PT-2020-5858 · Saltstack +3 · Saltstack Salt +3

Name of the Vulnerable Software and Affected Versions: SaltStack Salt versions through 3002 Description: The issue is related to the TLS module within SaltStack Salt, where certificates are created with weak file permissions. This weakness can be exploited to gain access to confidential data. The...

Shotwell is vulnerable

Shotwell is a Linux-based photo management software for the GNOME desktop environment. A security vulnerability exists in Shotwell version 0.22.0. The program fails to validate TLS and SSL certificates. An attacker can exploit this vulnerability to conduct a man-in-the-middle attack...

UBUNTU-CVE-2016-1000033

Shotwell version 0.22.0 and possibly other versions is vulnerable to a TLS/SSL certification validation flaw resulting in a potential for man in the middle attacks...

Remote Anonymous Denial of Service Vulnerability in OpenSSL (SSL Death Alert)

OpenSSL is an open source implementation of SSL used to implement strong encryption for network communications. OpenSSL is vulnerable to a remote anonymous denial of service vulnerability in that OpenSSL's implementation of the SSL/TLS protocol handshake allows a client to repeatedly send packets...

UBUNTU-CVE-2016-8610

A denial of service flaw was found in OpenSSL 0.9.8, 1.0.1, 1.0.2 through 1.0.2h, and 1.1.0 in the way the TLS/SSL protocol defined processing of ALERT packets during a connection handshake. A remote attacker could use this flaw to make a TLS/SSL server consume an excessive amount of CPU and fail...

Transport Layer Security (TLS) Version 1.2

Transport Layer Security TLS is a cryptographic protocol meant to provide security and data integrity for communications over TCP/IP networks. This protection will detect and block any use of TLSv1.2 protocol...

Transport Layer Security (TLS) Version 1.1

Transport Layer Security TLS is a cryptographic protocol meant to provide security and data integrity for communications over TCP/IP networks. TLSv1.1 is considered obsolete and insecure, and is deprecated in favor of a more advanced TLS protocol. This protection will detect and block any use of...

Transport Layer Security (TLS) Version 1.0

Transport Layer Security TLS is a cryptographic protocol meant to provide security and data integrity for communications over TCP/IP networks. TLSv1.0 is considered obsolete and insecure, and is deprecated in favor of a more advanced TLS protocol. This protection will detect and block any use of...

openssl: Padding oracle in AES-NI CBC MAC check

It was discovered that OpenSSL leaked timing information when decrypting TLS/SSL and DTLS protocol encrypted records when the connection used the AES CBC cipher suite and the server supported AES-NI. A remote attacker could possibly use this flaw to retrieve plain text from encrypted packets by...

TLS SHA-1 Spoofing Attack Vulnerability

TLS full name Transport Layer Security is a set of protocols used to provide confidentiality and data integrity between two communicating applications. A security vulnerability exists in SHA-1 in TLS version 1.2. This vulnerability can be exploited by an attacker to perform spoofing attacks...

RHEL 6 : openssl (RHSA-2016:2073)

An update for openssl is now available for Red Hat Enterprise Linux 6.7 Extended Update Support. Red Hat Product Security has rated this update as having a security impact of Important. A Common Vulnerability Scoring System CVSS base score, which gives a detailed severity rating, is available for...

CVE-2005-4900

SHA-1 is not collision resistant, which makes it easier for context-dependent attackers to conduct spoofing attacks, as demonstrated by attacks on the use of SHA-1 in TLS 1.2. NOTE: this CVE exists to provide a common identifier for referencing this SHA-1 issue; the existence of an identifier is...

LOGJAM: TLS connections which support export grade DHE key-exchange are vulnerable to MITM attacks

A flaw was found in the way the TLS protocol composes the Diffie-Hellman exchange for both export and non-export grade cipher suites. An attacker could use this flaw to downgrade a DHE connection to use export-grade key sizes, which could then be broken by sufficient pre-computation. This can lea...

Debian Security Advisory DSA 3688-1 (nss - security update)

Several vulnerabilities were discovered in NSS, the cryptography library developed by the Mozilla project. CVE-2015-4000 David Adrian et al. reported that it may be feasible to attack Diffie-Hellman-based cipher suites in certain circumstances, compromising the confidentiality and integrity of da...

DEBIAN-CVE-2016-7141

curl and libcurl before 7.50.2, when built with NSS and the libnsspem.so library is available at runtime, allow remote attackers to hijack the authentication of a TLS connection by leveraging reuse of a previously loaded client certificate from file for a connection for which no certificate has...
