Astra Linux – Vulnerability in Thunderbird

Thunderbird does 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 Samba

The fixes in 4.6.16, 4.7.9, 4.8.4, and 4.9.7 for CVE-2018-10919, which address the issue of confidential attributes being disclosed via LDAP filters, were insufficient. An attacker may be able to obtain confidential BitLocker recovery keys from a Samba AD DC...

Astra Linux – Vulnerability in unrar-nonfree

RARLAB’s UnRAR version prior to 6.12 on Linux and UNIX allowed directory traversal, enabling writing to files during an extraction operation also known as unpacking. This was demonstrated by creating a file named /.ssh/authorizedkeys. NOTE: WinRAR and Android RAR are not affected by this issue...

Astra Linux – Vulnerability in NTP

In NTP versions 4.2.8, 4.2.8p15, and 4.3.x, before 4.3.101, remote attackers could cause a denial of service memory consumption by sending packets. This occurs because memory is not released in situations where a CMAC key is used and associated with a CMAC algorithm in the ntp.keys file...

Astra Linux – Vulnerability in mbedtls

In Trusted Firmware Mbed TLS 2.24.0, a side-channel vulnerability exists in the decoding of Base64 PEM files. This vulnerability allows system-level administrator attackers to obtain information about secret RSA keys through a controlled-channel and side-channel attack on software running in...

Astra Linux – Vulnerability in OpenSSL

Issue summary: Generating excessively long X9.42 DH keys or checking overly long X9.42 DH keys or parameters can be very slow. Applications that use functions like DHgeneratekey to generate an X9.42 DH key may experience prolonged delays. Similarly, applications that use functions like...

Astra Linux – Vulnerability in Linux 5.10, Linux

In the Linux kernel, the following vulnerability has been resolved: powerpc/64: The jump labels are called before parseearlyparam is executed. On 64-bit systems, calling jumplabelinit within setupfeaturekeys is too late because static keys may be used in subroutines of parseearlyparam, which in...

Astra Linux – Vulnerability in golang-golang-x-net

An attacker can cause excessive memory usage in a Go server that accepts HTTP/2 requests. HTTP/2 server connections include a cache of HTTP header keys sent by the client. Although the total number of entries in this cache is limited, an attacker who sends very large keys can cause the server to...

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 found in Linux 5.15, Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: blk-mq: The crypto keyslot must be released before reporting I/O completion. Once all I/O using the blkcryptokey is completed, the file systems can call blkcryptoevictkey. However, the block layer currently does not call...

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...

Astra Linux – Vulnerability in Redis

Redis is an in-memory database that persists data on disk. Redis does not correctly identify keys accessed using SORTRO. As a result, it may grant users who execute this command access to keys that are not explicitly authorized by the ACL configuration. This issue exists in Redis 7.0 or later...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: KEYS: Trusted: dcp: Fix for leaking the blob encryption key Trusted keys unseal the key blob upon loading, but keep the sealed payload in the blob field. Thus, every subsequent read export simply converts this field to hexadecima...

Astra Linux – Vulnerability in Samba

A flaw was discovered in Samba. The security vulnerability occurs when the KDC and the kpasswd service share a single account and set of keys, allowing them to decrypt each other’s tickets. A user who has been requested to change their password can exploit this flaw to obtain and use tickets for...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: crypto: caam – fixed an overflow issue when dealing with long HMAC keys. When a key that is longer than the block size is provided, it is copied and then hashed into the actual key. The memory allocated for the copy needs to be...

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

Bluetooth BR/EDR devices with Secure Simple Pairing and Secure Connections support pairing in Bluetooth Core Specification 4.2 through 5.4. However, these devices are vulnerable to certain man-in-the-middle attacks, which force the use of a short key length. This vulnerability may lead to the...

Astra Linux – Vulnerability in Bouncycastle

Bouncy Castle for Java before version 1.73 contains a potential Denial of Service DoS issue within the Bouncy Castle org.bouncycastle.openssl.PEMParser class. This class parses OpenSSL PEM-encoded streams containing X.509 certificates, PKCS8-encoded keys, and PKCS7 objects. Parsing a file that...

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 exim4

Exim 4 before 4.94.2 allows Out-of-bounds Read because pdkimfinishbodyhash does not validate the relationship between sig-bodyhash.len and b-bh.len; thus, a crafted DKIM-Signature header might lead to the leakage of sensitive information from process memory...

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

In the Linux kernel, the following vulnerability has been resolved: bpf: Reject variable offset alu on PTRTOFLOWKEYS For PTRTOFLOWKEYS, the checkflowkeysaccess function only uses a fixed offset for validation. However, the variable offset ptr isn’t prohibited for this type of pointer. Therefore,...
