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 exim4

In versions of Exim prior to 4.99.3, in certain GnuTLS configurations, there is a remotely reachable use-after-free in the BDAT body parsing path. This issue is triggered when a client sends a TLS closenotify message during a CHUNKING transfer, followed by a final cleartext byte on the same TCP...

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...

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 – Vulnerabilities in Linux 5.10, Linux 5.15

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 found in Linux 5.15, Linux 6.1, Linux, Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: net: tls: handling of backlogging of crypto requests Since we are setting the CRYPTOTFMREQMAYBACKLOG flag on our requests to the crypto API, cryptoaeadencrypt,decrypt can return -EBUSY instead of -EINPROGRESS in valid situations...

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 Ruby 2.5, 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...

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...

Vulnerability in the Java SE, Oracle GraalVM Enterprise Edition product of Oracle Java SE component: JSSE. The supported versions affected are Java SE: 8u301, 11.0.12, 17; Oracle GraalVM Enterprise Edition: 20.3.3 and 21.2.0. This easily exploitable vulnerability allows an unauthenticated attacke...

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 complete function is...

Astra Linux – Vulnerability in Redis

Redis is an open-source, in-memory database that persists data on disk. In versions starting from 2.6 and prior to 7.4.3, an unauthenticated client can cause the output buffer to grow indefinitely, until the server runs out of memory or is terminated. By default, Redis’s configuration does not...

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 6.1

In the Linux kernel, the following vulnerability has been resolved: In TLS communication, there was an issue where we took a reference to psock after locking the RX lock, in order to avoid leaks. At the beginning of the tlsswrecvmsg function, we take a reference to psock, and then call...

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 found in Linux 5.10, Linux 6.1, Linux, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: net: tls: explicitly disallow disconnect Syzbot discovered that it can disconnect a TLS socket and then encounter various unexpected corner cases. I have a vague memory of Eric pointing this out to us a long time ago. Supporting...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: tls: Wait for pending async decryption if tlsstrpmsghold fails Async decryption calls tlsstrpmsghold to create a clone of the input skb, in order to hold references to the memory it uses. If we fail to allocate that clone,...

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...
