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

In the Linux kernel, the following vulnerability has been resolved: AppArmor: Fixed the race condition between freeing data and accessing it through the file system. AppArmor originally placed a reference to private data after removing the original entry from the file system. However, the inode m...

Astra Linux – Vulnerability in Flask

Flask is a lightweight WSGI web application framework. When all of the following conditions are met, a response containing data intended for one client may be cached and subsequently sent by the proxy to other clients. If the proxy also caches Set-Cookie headers, it may send one client’s session...

Astra Linux – Vulnerability in mbedtls

In Arm Mbed TLS before version 2.19.0, and Arm Mbed Crypto before version 2.0.0, when deterministic ECDSA is enabled, an RNG with insufficient entropy is used for blinding. This may allow an attacker to recover a private key through side-channel attacks if a victim signs the same message multiple...

Astra Linux – Vulnerability in nss

When performing EC scalar point multiplication, the wNAF point multiplication algorithm was used; this resulted in the leakage of partial information regarding the nonce used during signature generation. Given an electro-magnetic trace from several generations of signatures, the private key could...

Astra Linux – Vulnerability in Firefox and Thunderbird

An attacker who enumerated resources from the WebCompat extension could obtain a persistent UUID that identified the browser. This UUID could be used to switch between container-based modes and normal/private browsing mode, but not profiles. This vulnerability has been fixed in Firefox 140, Firef...

Astra Linux – Vulnerability in Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: md: Do not set mddev’s private field to NULL in raid0 with pers-free. In a normal stop process, the following sequence of operations occurs: domdstop | mdstop pers-free; mddev-private = NULL | mdfree free mddev The mdstop functio...

Astra Linux – Vulnerability in nss

NSS has demonstrated timing differences during the execution of DSA signatures, which can be exploited and may eventually lead to the leakage of private keys. This vulnerability affects Thunderbird versions 68.9.0, Firefox versions 77, and Firefox ESR versions 68.9...

Astra Linux – Vulnerability in Firefox and Thunderbird

When checking whether the Browsing Context was discarded in HttpBaseChannel, if the load group was not available, it was assumed that the Browsing Context had already been discarded. However, this assumption was not always true for private channels after the private session ended. This...

Astra Linux – Vulnerability in Python 3.11, Python 3.7

The “ipaddress” module contained incorrect information regarding whether certain IPv4 and IPv6 addresses were designated as “globally reachable” or “private”. This affected the isprivate and isglobal properties of the ipaddress.IPv4Address, ipaddress.IPv4Network, ipaddress.IPv6Address, and...

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 mbedtls

Before version 2.16.5 of Arm Mbed TLS, attackers could obtain sensitive information an RSA private key by monitoring cache usage during an import process...

Astra Linux – Vulnerability in Firefox

Firefox used to cache the last filename used for printing a file. When generating a filename for printing, Firefox usually suggests the web page title. The combination of caching and suggestion techniques may have led to the title of a website visited during private browsing mode being stored on...

Astra Linux – Vulnerability in Firefox

Multiple NSS NIST curves were vulnerable to a side-channel attack known as “Minerva”. This attack could potentially allow an attacker to recover the private key. This vulnerability affects Firefox versions less than 121...

Astra Linux – Vulnerability in Firefox

GNOME was leaking browser tab titles into system logs. This could potentially expose users’ browsing habits when they are using private tabs. This vulnerability affects Firefox versions earlier than 121...

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. A malicious FTP server can use the PASV response to trick Net::FTP into connecting back to a specified IP address and port. This potentially allows curl to extract information about services that would...

Astra Linux – Vulnerabilities in Linux 5.10, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: crypto: akcipher – default implementation for setting a private key Changes from v1: - The default implementation of setpubkey was removed. It is assumed that an implementation must always have this callback defined, as there are...

Astra Linux – Vulnerability in Firefox and Thunderbird

If the browser.privatebrowsing.autostart preference is enabled, IndexedDB files are not properly deleted when the window is closed. This preference is disabled by default in Firefox. This vulnerability affects Firefox 126, Firefox ESR 115.11, and Thunderbird 115.11...

Astra Linux – Vulnerability found in Linux 6.1, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: cloneprivatemnt: Make sure that the caller has CAPSYSADMIN in the correct user namespaces. What we want is to ensure that clone does not expose something hidden by a mount that we wouldn’t be able to undo. “ wouldn’t be able to...

Astra Linux – Vulnerability in Firefox, Thunderbird

Push notifications stored on disk in private browsing mode were not encrypted, potentially allowing the leakage of sensitive information. This vulnerability affects Firefox 117, Firefox ESR 115.2, and Thunderbird 115.2...

Astra Linux – Vulnerability in gnupg1

Libgcrypt before version 1.7.8 is vulnerable to a cache-side-channel attack that can lead to a complete failure of the RSA-1024 algorithm. This attack occurs when the left-to-right method is used for computing the sliding-window expansion. It is believed that the same attack also works on the...
