Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: crypto: safexcel – Added error handling for dmamapsg calls. The macro dmamapsg function may return 0 in case of an error. This patch enables checks in case of a macro failure and ensures that previously mapped buffers are unmappe...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: crypto: tegra – Added the missing CRYPTOALGASYNC flag. The tegra crypto driver failed to set CRYPTOALGASYNC for its asynchronous algorithms. As a result, the crypto API would select these algorithms for users who request only...

Astra Linux – Vulnerability in golang-go.crypto

Applications and libraries that misuse the connection.serverAuthenticate function via the ServerConfig.PublicKeyCallback callback field may be susceptible to authorization bypasses. The documentation for ServerConfig.PublicKeyCallback states that “Calling this function does not guarantee that the...

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: scomp – fixed the req-dst buffer overflow issue. The size of the req-dst buffer should be checked before copying data from scompscratch-dst to avoid the req-dst buffer overflow problem...

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 Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: ima: Fixed a potential memory leak in imainitcrypto. If the SHA1 template is unable to be allocated, IMA fails to initialize and exits without freeing the imaalgoarray. Adding the necessary kfree call for imaalgoarray will preven...

Astra Linux – Vulnerability in Golang-1.15

In Go versions before 1.14.14 and 1.15.x, as well as before 1.15.7, the crypto/elliptic/p224.go file may generate incorrect outputs due to a underflow of the lowest limb during the final complete reduction of the P-224 field...

Astra Linux – Vulnerability in mbedtls

The ECDSA signature implementation in ecdsa.c in Arm Mbed Crypto 2.1 and Mbed TLS from 2.19.1 onwards does not reduce the blinded scalar before computing the inverse. This allows a local attacker to recover the private key through side-channel attacks...

Astra Linux – Vulnerability in golang-go.crypto

The x/crypto/ssh package in version 0.0.0-20211202192323-5770296d904e of golang.org/x/crypto allows an attacker to cause a panic in an SSH server...

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

In the Linux kernel, the following vulnerabilities have been resolved: TLS: Fixed a race condition between TX work scheduling and socket closure. Similar to previous commits, the submitting thread recvmsg/sendmsg may exit as soon as the async crypto handler’s call completes. Reordering the...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: crypto: acomp – Fixed CFI failures due to type punning. To avoid crashes when control flow integrity is enabled, ensure that the workspace “stream” uses a consistent type for function calls, and invoke functions through a functio...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerabilities have been resolved: crypto: aead – Fixed handling of reqsize The commit afddce13ce81d “crypto: api – Added reqsize to cryptoalg” introduced the crareqsize field in the cryptoalg struct to replace the type-specific reqsize fields. It seems this...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerabilities have been resolved: crypto: marvell/octeontx – prevents integer overflows The value of “codelength” comes from the firmware file. If your firmware is untrusted, there’s likely very little you can do to protect yourself. Nevertheless, we still try...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: virtio-crypto: fixed a memory leak in virtiocryptoalgskcipherclosesession The variable 'vcctrlreq' is allocated in virtiocryptoalgskcipherclosesession, and should be freed in the invalid ctrlstatus-status error handling case...

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 Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: ksmbd: Compare MACs in constant time To prevent timing attacks, MAC comparisons need to be performed in constant time. Replace the memcmp function with the correct function, cryptomemneq...

Astra Linux – Vulnerability in Linux 5.10
