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 gnutls28

A vulnerability was identified: the response times for malformed ciphertexts in RSA-PSK ClientKeyExchange differ from those of ciphertexts with correct PKCS1 v1.5 padding...

Astra Linux – Vulnerability in gnutls28

A timing side-channel vulnerability in the handling of RSA ClientKeyExchange messages was discovered in GnuTLS. This side-channel can be used to recover the key encrypted in the RSA ciphertext across a network, in a Bleichenbacher-style attack. To successfully decrypt the data, the attacker would...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerabilities have been resolved: fscrypt: stopped using the keyring subsystem for fscryptmasterkey. The approach of having fs/crypto/ manage the fscryptmasterkey structures internally as payloads within “struct key” objects contained in a “struct key” keyring...

Astra Linux – Vulnerability in bind9

The code that processes control channel messages sent to named recursively calls certain functions during packet parsing. The recursion depth is limited only by the maximum acceptable packet size; depending on the environment, this may cause the packet-parsing code to run out of available stack...

Astra Linux – Vulnerabilities in Linux, Linux-5.10, Linux-5.15, Linux-6.1

In the Linux kernel, the following vulnerability has been resolved: crypto: aead,cipher – The key buffer is zeroed after use. I.G 9.7.B for FIPS 140-3 specifies that variables temporarily holding cryptographic information should be zeroed once they are no longer needed. This is achieved by using...

Astra Linux – Vulnerability found in Linux 5.15, Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: crypto: ecdh – explicitly zeroes privatekey. The privatekey is overwritten with the key parameter passed in by the caller if present, or alternatively with a newly generated private key. However, it is possible that the caller...

Astra Linux – Vulnerability in Ceph

An authentication flaw was discovered in Ceph versions prior to 14.2.20. When the monitor processes CEPHXGETAUTHSESSIONKEY requests, it does not sanitize otherkeys, allowing for key reuse. An attacker who can request a globalid can exploit the ability of any user to request a globalid that has...

Astra Linux – Vulnerability in Firefox

Form validation popups may capture escape key presses. Therefore, spamming form validation messages can be used to prevent users from exiting full-screen mode. This vulnerability affects Firefox 128 and Thunderbird 128...

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: net: openvswitch: fixed the nested key length validation in the set action. It is not safe to access nlalenovskey if the data is smaller than the netlink header. Ensure that the attribute is valid first...

Astra Linux – Vulnerability in gnutls28

A flaw was discovered in libgnutls. A remote attacker could trigger a short heap overread by sending an extremely short premaster secret during an RSA key exchange to a server that uses an RSA key backed by a PKCS11 token. This memory corruption vulnerability could lead to information disclosure...

Astra Linux – Vulnerabilities in Linux 5.10, Linux 5.15, Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: net/sctp: A null dereference in the sctpdisposition sctpsfdo51Dce function has been fixed. If newasoc-peer.adaptationind=0, sctpulpeventmakeauthkey=0, and sctpulpeventmakeauthkey returns 0, then the variable aiev remains zero, an...

Astra Linux – Vulnerability in golang-go.crypto

SSH servers that implement file transfer protocols are vulnerable to a denial of service attack from clients that complete the key exchange slowly, or not at all. This results in pending data being read into memory but never being transmitted...

Astra Linux – Vulnerability in Golang-1.19

Extremely large RSA keys in certificate chains can cause clients and servers to spend significant CPU time verifying signatures. With this fix, the size of RSA keys transmitted during handshake operations is limited to 8192 bits or less. Based on a survey of publicly trusted RSA keys, there are...

Insertion of Sensitive Information into Log File

Overview Affected versions of this package are vulnerable to Insertion of Sensitive Information into Log File in the process of configuring an AES key of non-standard length, where the provided value is padded with random characters and the resulting key is output to log files. An attacker can...

crypto/tls: golang: Golang crypto/tls: Denial of Service via indefinite KeyUpdate messages

A flaw was found in the crypto/tls package, part of golang. A malicious client can exploit this vulnerability by continuously sending KeyUpdate messages to a server. This forces the server to perform indefinite key derivation operations, leading to resource exhaustion and a Denial of Service DoS...

Astra Linux – Vulnerability in mbedtls

A issue was discovered in Arm Mbed TLS prior to version 2.23.0. Due to a side channel in modular exponentiation, an RSA private key used in a secure enclave could be disclosed...

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

In the Linux kernel, the following vulnerability has been resolved: Keys: Fixed the issue of linking a duplicate key to a keyring’s assocarray. When making a DNS query within the kernel using dnsquery, the request code can, in rare cases, create a duplicate index key in the assocarray of the...

Astra Linux – Vulnerability in Thunderbird

When importing a revoked key with “key compromise” as the revocation reason, Thunderbird did not update the existing copy of the key that was not yet revoked. As a result, the existing key remained unrevoked. Revocation statements that used another revocation reason, or those that did not specify...

Astra Linux – Vulnerability in Thunderbird

Thunderbird unprotects a secret OpenPGP key before using it for decryption, signing, or key import tasks. If the task fails, the secret key may remain in memory in an unprotected state. This vulnerability affects Thunderbird versions earlier than 78.8.1...
