Astra Linux – Vulnerability in Thunderbird

Thunderbird did not check whether the user ID associated with an OpenPGP key has a valid self-signature. An attacker may create a forged version of an OpenPGP key, either by replacing the original user ID or by adding another user ID. If Thunderbird imports and accepts the forged key, the...

Astra Linux – Vulnerability in Thunderbird

An attacker may carry out a DoS attack to prevent a user from sending encrypted emails to a correspondent. If an attacker creates a crafted OpenPGP key with a subkey that has an invalid self-signature, and the Thunderbird user imports the crafted key, then Thunderbird may attempt to use the inval...

Astra Linux – Vulnerability in Firefox and Thunderbird

The Opportunistic Encryption feature of HTTP2 RFC 8164 allows a connection to be transparently upgraded to TLS while maintaining the visual properties of an HTTP connection. This means that the connection remains within the same origin as unencrypted connections on port 80. However, if a second...

Astra Linux – Vulnerability in erlang-jose

In versions 1.11.6 and earlier of erlang-jose also known as JOSE for Erlang and Elixir, attackers can exploit this vulnerability to cause a denial of service attack, resulting in high CPU usage. This vulnerability stems from a large p2c value in the JOSE header...

Astra Linux – Vulnerability in OpenSSL

Issue summary: An application attempting to decrypt messages encrypted using password-based encryption in CMS can trigger an out-of-bounds read and write attack. Impact summary: This out-of-bounds read attack may cause a system crash, leading to a denial of service for the application. The...

Astra Linux – Vulnerability in opensc

A vulnerability was discovered in OpenSC, where the removal of PKCS1 encryption padding is not implemented in a way that ensures side-channel resistance. This issue may lead to the potential leakage of private data...

Astra Linux – Vulnerability in Qemu

A flaw was discovered in the QEMU virtual crypto device during handling of data encryption/decryption requests in virtiocryptohandlesymreq. There is no check for the values of srclen and dstlen in virtiocryptosymophelper, which may lead to a heap buffer overflow if these values differ...

Astra Linux – Vulnerability in Linux

The 802.11 standard that underpins Wi-Fi Protected Access WPA, WPA2, and WPA3 and Wired Equivalent Privacy WEP does not require that all fragments of a frame be encrypted with the same key. An adversary can exploit this weakness to decrypt selected fragments when another device sends fragmented...

Astra Linux – Vulnerability in Thunderbird

If a Thunderbird user has previously imported Alice’s OpenPGP key, and Alice has extended the validity period of her key, but Alice’s updated key has not yet been imported, an attacker may send an email containing a crafted version of Alice’s key with an invalid subkey. In this case, Thunderbird...

Astra Linux – Vulnerability in Linux

Astra Linux – Vulnerability in Ceph

A key length flaw was discovered in Red Hat Ceph Storage. An attacker can exploit the fact that the key length is incorrectly passed during the encryption algorithm process, resulting in the creation of a non-random key. Such a key is weaker and can be exploited to compromise the confidentiality...

Astra Linux – Vulnerability in Thunderbird

If a Thunderbird user responded to a crafted HTML email containing a meta tag, where the meta tag had the http-equiv="refresh" attribute, and the content attribute specified a URL, then Thunderbird would initiate a network request to that URL, regardless of any configuration settings that block...

Astra Linux – Vulnerability in Thunderbird

If a MIME email combines OpenPGP and OpenPGP MIME data in a certain way, Thunderbird repeatedly attempts to process and display the message. This could cause Thunderbird’s user interface to lock up and no longer respond to the user’s actions. An attacker could send a crafted message with this...
