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 wpa

The implementation of PEAP in wpasupplicant through version 2.10 allows for authentication bypass. To successfully carry out this attack, wpasupplicant must be configured to not verify the network’s TLS certificate during Phase 1 authentication. Additionally, the eappepeapdecrypt vulnerability ca...

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 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 LibreOffice

A vulnerability in certificate validation in LibreOffice’s “LibreOfficeKit” mode disables TLS certificate verification. LibreOfficeKit can be used to access LibreOffice functionality through C/C++. Typically, this is used by third-party components to reuse LibreOffice as a library for converting,...

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 originating from the...

Astra Linux - Vulnerability in Golang-1.19

Within HostnameError.Error, when constructing an error string, there is no limit to the number of hosts that will be printed out. Moreover, the error string is created through repeated string concatenation, resulting in quadratic runtime. Therefore, a certificate provided by a malicious actor can...

Astra Linux – Vulnerability in Thunderbird

Thunderbird versions prior to 91.3.0 are vulnerable to a heap overflow vulnerability described in CVE-2021-43527 when processing S/MIME messages. Thunderbird versions 91.3.0 and later will not call the vulnerable code when processing S/MIME messages that contain certificates with DER-encoded DSA ...

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 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 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 LibreOffice

The Certificate Validation user interface in LibreOffice may contain potential vulnerabilities. Signed macros are scripts that have been digitally signed by the developer using a cryptographic signature. When a document containing a signed macro is opened, LibreOffice displays a warning before th...

Astra Linux – Vulnerability in Heimdal

Heimdal is an implementation of ASN.1/DER, PKIX, and Kerberos. Versions prior to 7.7.1 are vulnerable to a denial-of-service vulnerability in Heimdal’s PKI certificate validation library. This vulnerability affects the KDC via PKINIT and kinit via PKINIT, as well as any third-party applications...

Astra Linux – Vulnerability in OpenLDAP

An integer underflow was discovered in OpenLDAP before version 2.4.57. This issue led to a crash in the slapd process during the Certificate List Exact Assertion processing, resulting in a denial of service...

Astra Linux – Vulnerability in StrongSwan

Before version 5.9.8, StrongSwan allowed remote attackers to cause a denial of service in the revocation plugin by sending a crafted end-entity and intermediate CA certificate that contained a CRL/OCSP URL pointing to a server under the attacker’s control that did not respond properly. In some...

Astra Linux – Vulnerability in curl

When curl is instructed to use the Certificate Status Request TLS extension, also known as OCSP stapling, to verify that the server certificate is valid, it may fail to detect certain OCSP issues and instead incorrectly consider the response to be fine. If the returned status reports an error oth...
