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...

Astra Linux – Vulnerability in mbedtls

A timing side channel in mbedtlsssldecryptbuf in library/sslmsg.c in Trusted Firmware Mbed TLS from version 2.23.0 allows an attacker to obtain secret key information. This issue affects the CBC mode, as it involves a calculated time difference based on the padding length...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: ksmbd: The issue of slub overflow in ksmbddecodentlmsspauthblob has been fixed. If authblob-SessionKey.Length is larger than the size of the session key CIFSKEYSIZE, slub overflow can occur in the key exchange process. The functi...

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

In the Linux kernel, the following vulnerabilities have been resolved: mac802154: fixed the issue where key resources were released in mac802154llseckeydel. The mac802154llseckeydel function can free resources associated with a key directly, without following the RCU rules for waiting before the...

Astra Linux – Vulnerability in Heimdal, Samba

Before version 7.7.1, Heimdal allowed remote attackers to execute arbitrary code due to an invalid free operation in the ASN.1 codec used by the Key Distribution Center KDC...

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 libssh

A flaw was discovered in the abstract layer of the libssh library responsible for message digest MD operations, which is implemented by different supported crypto backends. The return values from these operations were not properly checked, which could lead to low-memory situations, NULL...

Astra Linux – Vulnerability in OpenSSL

Issue Summary: Checking excessively long DH keys or parameters can be very slow. Impact Summary: Applications that use functions like DHcheck, DHcheckex, or EVPPKEYparamcheck to check DH keys or parameters may experience prolonged delays. If the keys or parameters are obtained from an untrusted...

Astra Linux – Vulnerability in openssl1.0

In situations where an attacker receives automated notifications of the success or failure of a decryption attempt, an attacker can recover the CMS/PKCS7 transport encryption key after sending a very large number of messages to be decrypted. They can also decrypt any RSA-encrypted message encrypt...

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 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 Linux

In the Linux kernel, the following vulnerabilities have been resolved: cifs: Return the correct error code from smb2getenckey Avoid a warning if the error is passed back up: 440700.376476 CIFS VFS: \otters.example.com cryptmessage: Could not get encryption key 440700.386947 ------------ Cut here...

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...

Astra Linux – Vulnerability in etcd

A cross-site request forgery flaw was discovered in etcd 3.3.1 and earlier. An attacker can create a website that attempts to send a POST request to the etcd server and modify a key. Adding a key is done using a PUT operation, so it seems theoretically safe but PUT operations cannot be performed...

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

In the Linux kernel, the following vulnerability has been resolved: wifi: mac80211: fix potential key use-after-free When ieee80211gtkrekeyadd is called, and ieee80211gtkrekeyadd returns 0 due to KRACK protection identical key reinstall, ieee80211gtkrekeyadd will still return a pointer to the key...

Astra Linux – Vulnerability in OpenSSL

Issue summary: Processing a maliciously formatted PKCS12 file may cause OpenSSL to crash, leading to a potential Denial of Service attack. Impact summary: Applications that load files in PKCS12 format from untrusted sources may experience abrupt termination. A PKCS12 format file can contain...

Astra Linux – Vulnerability in Erlang

There is a vulnerability in the validation of certificates in the Erlang OTP publickey pubkeyocsp module, which allows forged OCSP responses signed with an expired responder certificate to be accepted as valid. The OCSP response verification in pubkeyocsp:verifyresponse/5 and...

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...
