Ivanti Connect Secure - Stack-based Buffer Overflow

Ivanti Connect Secure 22.7R2.5, Ivanti Policy Secure 22.7R1.2, and Ivanti Neurons for ZTA gateways 22.7R2.3 contain a stack-based buffer overflow in the clientCapabilities parameter handling. This vulnerability allows remote unauthenticated attackers to execute arbitrary code through IF-T TLS...

Astra Linux – Vulnerability in curl

libcurl will reuse a previously established connection even when options related to TLS or SSH have been changed, which should prevent such reuses. libcurl stores previously used connections in a connection pool, allowing for reuse if one of them matches the current setup. However, several TLS an...

Astra Linux – Vulnerability found in Linux 5.15, Linux 6.1, Linux, Linux 5.10

In the Linux kernel, the following vulnerabilities have been resolved: TLS: Fixed a race condition between the async notify and socket close operations. The thread that submitted the request the one that called recvmsg/sendmsg may exit as soon as the async crypto handler’s call completes. Any cod...

Astra Linux – Vulnerability in openjdk-11

Vulnerability in the Java SE, Oracle GraalVM Enterprise Edition product of Oracle Java SE component: JSSE. The supported versions affected are Java SE: 7u311, 8u301, 11.0.12, 17; Oracle GraalVM Enterprise Edition: 20.3.3 and 21.2.0. The vulnerability is difficult to exploit; an unauthenticated...

Astra Linux – Vulnerability in Golang-1.19

Verifying a certificate chain that contains a certificate with an unknown public key algorithm will cause Certificate.Verify to panic. This affects all crypto/TLS clients, as well as servers that have Config.ClientAuth set to VerifyClientCertIfGiven or RequireAndVerifyClientCert. The default...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerabilities have been resolved: - net: tls: Fixed a use-after-free issue related to partial reads and async decryption. tlsdecryptsg does not take a reference to the pages from clearskb. Therefore, the putpage function in tlsdecryptdone releases these pages,...

Astra Linux – Vulnerability in Apache2

Insufficient escaping of user-supplied data in modssl in Apache HTTP Server 2.4.63 and earlier allows an untrusted SSL/TLS client to insert escape characters into log files in some configurations. In a logging configuration where CustomLog is used with "%varnamex" or "%varnamec" to log variables...

Astra Linux – Vulnerability in python-cryptography

A flaw was discovered in the python-cryptography package. This issue may allow a remote attacker to decrypt captured messages in TLS servers that use RSA key exchanges, which could result in the exposure of confidential or sensitive data...

EUVD-2026-97778

A flaw was found in openstack-network-exporter. When an operator configures user authentication but omits or misconfigures Transport Layer Security TLS, the basic authentication mechanism is silently bypassed. This fail-open design allows an adjacent network attacker to access sensitive Open...

CVE-2026-83535

A flaw was found in openstack-network-exporter. When an operator configures user authentication but omits or misconfigures Transport Layer Security TLS, the basic authentication mechanism is silently bypassed. This fail-open design allows an adjacent network attacker to access sensitive Open...

SUSE CVE-2026-71885

In Bouncy Castle for Java before 1.86, the Messaging Layer Security MLS, RFC 9420 implementation did not bind an X.509 credential to a LeafNode's signaturekey. LeafNode.verify checked a leaf's signature against the signaturekey carried in the leaf itself, while the credential's X.509 certificate...

Astra Linux – Vulnerability in Python 3.7, Python 2.7, Pypy

A vulnerability was discovered in Python before version 3.8.18, 3.9.x before version 3.9.18, 3.10.x before version 3.10.13, and 3.11.x before version 3.11.5. This vulnerability primarily affects servers such as HTTP servers that use TLS client authentication. When a TLS server-side socket is...

Astra Linux – Vulnerability in Erlang

In Erlang/OTP versions prior to 23.3.4.15, 24.x before 24.3.4.2, and 25.x before 25.0.2, there was a situation where Client Authentication Bypass occurred in certain client-certification scenarios for SSL, TLS, and DTLS...

Astra Linux – Vulnerability in Node.js

A flaw in Node.js’ TLS error handling allows remote attackers to crash or exhaust resources of a TLS server when pskCallback or ALPNCallback is used. Synchronous exceptions thrown during these callbacks bypass standard TLS error handling mechanisms such as tlsClientError and error, causing either...

Astra Linux – Vulnerability found in Linux 5.15, Linux 6.1, Linux, Linux 5.10

In the Linux kernel, the following vulnerabilities have been resolved: TLS: Fixed a race condition between TX work scheduling and socket closure. Similar to previous commits, the submitting thread recvmsg/sendmsg may exit as soon as the async crypto handler’s call completes. Reordering the...

Astra Linux – Vulnerability in Linux, Linux 5.10

In the Linux kernel, the following vulnerabilities have been resolved: net/tls: Fixed the reversed sign in calls to tlserrabort. sk-skerr seems to expect a positive value. This convention is not always followed by ktls, which can lead to memory corruption in other code. For example: c kworker...

Astra Linux – Vulnerability in Linux 5.10, Linux

In the Linux kernel, the following vulnerability has been resolved: net/tls: The bug related to slab-out-of-bounds condition in decryptinternal has been fixed. The memory size of tlsctx-rx.iv for AES128-CCM is 12 bytes when tlssetswoffload is called. The return value of cryptoaeadivsize for...

Astra Linux – Vulnerability in curl

When curl version 7.20.0 or later connects to an IMAP or POP3 server to retrieve data using STARTTLS to upgrade to TLS security, the server can send multiple responses at once, which are cached by curl. In this case, curl upgrades to TLS, but it does not discard the cached responses. Instead, it...

Astra Linux – Vulnerability in Jetty9

In Eclipse Jetty 7.2.2 to 9.4.38, 10.0.0alpha0 to 10.0.1, and 11.0.0alpha0 to 11.0.1, CPU usage can reach 100% when receiving a large invalid TLS frame...

Astra Linux – Vulnerability in Ruby2.5, JRuby

A issue was discovered in Ruby between versions 2.6.7, 2.7.x up to 2.7.3, and 3.x up to 3.0.1. The Net::IMAP library does not raise an exception when the StartTLS command fails with an unknown response. This may allow man-in-the-middle attackers to bypass TLS protections by leveraging the network...
