An attacker could create a PKCS 12 certificate bundle in a way that allows arbitrary memory writes through the mishandled Safe Bag attributes of PKCS 12. This vulnerability affects Firefox 110, Thunderbird 102.8, and Firefox ESR 102.8...

Astra Linux – Vulnerability in curl

There is a vulnerability in the handling of certificate validation in curl v8.1.0, particularly in how wildcard patterns are matched when listed as “Subject Alternative Name” in TLS server certificates. Curls can be modified to use its own name matching function for TLS, rather than the one...

Astra Linux - уязвимость в tomcat9

CLIENTCERT authentication does not fail as expected in some scenarios when soft fail is disabled and FFM is used in Apache Tomcat. This issue affects Apache Tomcat: versions from 11.0.0-M14 through 11.0.20, from 10.1.22 through 10.1.53, and from 9.0.92 through 9.0.116. Users are recommended to...

Astra Linux – Vulnerability in Apache Log4j2

Improper validation of certificates with host mismatches in the Apache Log4j SMTP appender. This could allow an SMTPS connection to be intercepted by a man-in-the-middle attack, thereby leaking any log messages sent through that appender. This issue has been fixed in Apache Log4j 2.12.3 and 2.13....

Astra Linux – Vulnerability in ca-certificates

Certifi is a curated collection of Root Certificates designed to validate the reliability of SSL certificates and verify the identity of TLS hosts. On December 7, 2022, Certifi removed Root Certificates from “TrustCor” from the root store. These certificates are currently being removed from...

Astra Linux – Vulnerability in Linux

The Linux kernel up to version 5.8.13 does not properly enforce the Secure Boot Forbidden Signature Database also known as dbx protection mechanism. This issue affects the certs/blacklist.c and certs/systemkeyring.c files...

Astra Linux – Vulnerability in Golang 1.19, Golang 1.23

A certificate with a URI that has an IPv6 address and a zone ID may incorrectly satisfy a URI name constraint that applies to the certificate chain. Certificates containing URIs are not allowed in web PKIs; therefore, this only affects users of private PKIs that use URIs...

Astra Linux – Vulnerability in Bouncycastle

The Bouncy Castle For Java version prior to 1.74 is affected by an LDAP injection vulnerability. This vulnerability only affects applications that use the LDAP CertStore provided by Bouncy Castle to validate X.509 certificates. During the certificate validation process, Bouncy Castle inserts the...

Astra Linux – Vulnerability in curl

libcurl accidentally skips the certificate verification for QUIC connections when connecting to a host specified as an IP address in the URL. As a result, it does not detect impostor attacks or man-in-the-middle attacks...

Astra Linux – Vulnerability in Thunderbird

The OCSP revocation status of recipient certificates was not checked when sending S/MIME encrypted emails. As a result, revoked certificates were accepted. This bug affected Thunderbird versions from 68 to 102.9.1. This vulnerability affects Thunderbird versions earlier than 102.10...

Astra Linux – Vulnerability in OpenLDAP

An integer underflow was discovered in OpenLDAP before version 2.4.57, which led to slapd crashes during the Certificate Exact Assertion processing, resulting in a denial of service schemainit.c serialNumberAndIssuerCheck...

Astra Linux – Vulnerability in curl

Curl versions 7.41.0 through 7.73.0 are vulnerable to a flaw related to improper checks for certificate revocation, due to insufficient verification of the OCSP response...

Astra Linux – Vulnerability in qt4-x11, qtbase-opensource-src

A issue was discovered in Qt before version 5.15.15, in versions 6.x before 6.2.9, and in versions 6.3.x through 6.5.x before 6.5.2. Certificate validation for TLS does not always consider whether the root of a chain is a configured CA certificate...

Astra Linux – Vulnerability in OpenSSL

A security vulnerability has been identified in all supported versions of OpenSSL, related to the verification of X.509 certificate chains that include policy constraints. Attackers may be able to exploit this vulnerability by creating a malicious certificate chain that triggers exponential use o...

Astra Linux – Vulnerability in OpenSSL

Issue summary: Processing some specially crafted ASN.1 object identifiers or data containing them may be very slow. Impact summary: Applications that use OBJobj2txt directly, or use any of the OpenSSL subsystems such as OCSP, PKCS7/SMIME, CMS, CMP/CRMF, or TS without a message size limit may...

Astra Linux – Vulnerability in OpenSSL

Applications that use non-default options when verifying certificates may be vulnerable to attacks from a malicious Certificate Authority CA to circumvent certain checks. Invalid certificate policies in leaf certificates are silently ignored by OpenSSL, and other certificate policy checks for tho...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: NFS: Check the TLS certificate fields in nfsmatchclient If the TLS security policy is of type RPCXPRTSECTLSX509, then the certserial and privkeyserial fields also need to match, as they define the client’s identity, as presented ...

Astra Linux – Vulnerability in curl

Curl versions 7.63.0 through 7.75.0 include a vulnerability that allows a malicious HTTPS proxy to intercept connections by mishandling TLS 1.3 session tickets. When using an HTTPS proxy and TLS 1.3, libcurl may misinterpret session tickets sent from the HTTPS proxy as those coming from the remot...

crypto/tls: crypto/tls: Incorrect certificate validation during TLS session resumption

A flaw was found in the crypto/tls component. This vulnerability occurs during Transport Layer Security TLS session resumption when certificate authority CA settings are modified between the initial and resumed handshakes. An attacker could exploit this to bypass certificate validation, allowing ...
