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 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 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 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 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...
