DEBIAN-CVE-2020-14058

An issue was discovered in Squid before 4.12 and 5.x before 5.0.3. Due to use of a potentially dangerous function, Squid and the default certificate validation helper are vulnerable to a Denial of Service when opening a TLS connection to an attacker-controlled server for HTTPS. This occurs becaus...

The vulnerability of the statem/statem.c and statem/statem_lib.c components of the OpenSSL library allows a attacker to cause a service failure.

The vulnerability of the statem/statem.c and statem/statemlib.c components of the OpenSSL library is related to a bug in the resource consumption control mechanism. Exploiting this vulnerability could allow an attacker to cause a service failure through a specially crafted TLS message...

The vulnerability of the statem/statem.cc component in the OpenSSL library allows a attacker to gain unauthorized access to confidential data, cause service failures, or compromise data integrity.

The vulnerability of the statem/statem.cc component in the OpenSSL library is related to the use of memory areas after they are freed. Exploiting this vulnerability can allow an attacker to gain unauthorized access to confidential data, cause service failures, or compromise data integrity through...

gnutls: session resumption works without master key allowing MITM

A flaw was found in GnuTLS, in versions starting from 3.6.4, where it does not session the ticket encryption key in a secure fashion by the application which is connecting. This flaw allows an attacker to craft a man-in-the-middle-attack, with the ability to bypass the TLS1.3 authentication and...

The vulnerability of the SSL_check_chain function in the TLS protocol implementation of the OpenSSL library involves the possibility of reassigning the null pointer due to incorrect processing of the “signature_algorithms_cert” extension in TLS. This allows a perpetrator to cause a service failure.

The vulnerability of the SSLcheckchain function in the TLS protocol implementation of the OpenSSL library is related to the possibility of replacing the zero pointer due to incorrect processing of the “signaturealgorithmscert” extension in TLS. Exploiting this vulnerability can allow a malicious...

DEBIAN-CVE-2020-14954

Mutt before 1.14.4 and NeoMutt before 2020-06-19 have a STARTTLS buffering issue that affects IMAP, SMTP, and POP3. When a server sends a "begin TLS" response, the client reads additional data e.g., from a man-in-the-middle attacker and evaluates it in a TLS context, aka "response injection."...

DEBIAN-CVE-2020-14929

Alpine before 2.23 silently proceeds to use an insecure connection after a /tls is sent in certain circumstances involving PREAUTH, which is a less secure behavior than the alternative of closing the connection and letting the user decide what they would like to do...

wildfly: The 'enabled-protocols' value in legacy security is not respected if OpenSSL security provider is in use

A flaw was found when an OpenSSL security provider is used with Wildfly, the 'enabled-protocols' value in the Wildfly configuration isn't honored. An attacker could target the traffic sent from Wildfly and downgrade the connection to a weaker version of TLS, potentially breaking the encryption...

ALPINE-CVE-2020-13777

GnuTLS 3.6.x before 3.6.14 uses incorrect cryptography for encrypting a session ticket a loss of confidentiality in TLS 1.2, and an authentication bypass in TLS 1.3. The earliest affected version is 3.6.4 2018-09-24 because of an error in a 2018-09-18 commit. Until the first key rotation, the TLS...
