Astra Linux - уязвимость в linux-6.1, linux-5.15

In the Linux kernel, the following vulnerability has been resolved: netfilter: brnetfilter: do not check the confirmed bit in brnflocalin after confirmation. When sending a broadcast packet to a tap device, which is added to a bridge, the brnflocalin function is called to confirm the conntrack. I...

In the Linux kernel, the following vulnerabilities have been resolved: ftrace: Clean up the hash of directfunctions in case of register failures. The following GPF errors occur when registerftracedirect fails: General protection fault, likely for non-canonical addresses \ 0x200000000000010: 0000 ...

Astra Linux - уязвимость в parsec

The vulnerability of the hashinitialize function in the PARSEC security subsystem is related to the assignment of a null pointer. Exploiting this vulnerability allows an attacker to cause a service failure...

Astra Linux - уязвимость в linux-6.1

In the Linux kernel, the following vulnerability has been resolved: virtionet: Added a check for hashkeylength. A check for hashkeylength was added in virtnetprobe to avoid possible out-of-bounds errors when setting/read the hash key...

In the Linux kernel, the following vulnerabilities have been resolved: ksmbd: The issue related to “slab-use-after-free” in smb3preauthhashrsp has been fixed. The function ksmbdusersessionput should be called within smb3preauthhashrsp. This will prevent the session from being freed before calling...

In the Linux kernel, the following vulnerabilities have been resolved: netfilter: ipset: Fixed issues related to region locking in hash types. The region locking mechanism introduced in v5.6-rc4 included three macros for handling region locks: ahashbucketstart, ahashbucketend which return the sta...

Astra Linux - уязвимость в node-elliptic

The Elliptic package 6.5.7 for Node.js, in its ECDSA implementation, does not correctly verify valid signatures when the hash contains at least four leading 0 bytes, and when the order of the elliptic curve’s base point is smaller than the hash, due to an truncateToN anomaly. This results in vali...

In the Linux kernel, the following vulnerabilities have been resolved: dma-debug: fixed a possible deadlock in radixlock. radixlock should not be held while holding dmahashentryidx.lock. Otherwise, a deadlock scenario may occur when the dma debug API is called while holding rqlock. CPU0 CPU1 CPU2...

Astra Linux - уязвимость в sudo

In Sudo version 1.8.29, the fact that a user has been blocked for example, by using the “!” character in the shadow file instead of a password hash was not taken into consideration. This allows an attacker who has access to a Runas ALL sudoer account to impersonate any blocked user. NOTE: The...

Astra Linux - уязвимость в 389-ds-base

A flaw was discovered in 389-ds-base. If an asterisk is imported as password hashes, either accidentally or maliciously, then any password will successfully match during authentication, instead of being inactive. This flaw allows an attacker to successfully authenticate as a user whose password h...

In the Linux kernel, the following vulnerability has been resolved: bpf: Fixed the exclusive map memory leak When exclproghash is 0 and exclproghashsize is non-zero, the map also needs to be freed. Otherwise, the map memory will not be reclaimed, similar to the memory leak issue reported by syzbo...

Astra Linux - уязвимость в linux-5.10

In the Linux kernel, the following vulnerability has been resolved: virtio-net: Zeroed unused hash fields When a GSO tunnel is negotiated, the virtionethdrtnlfromskb function attempts to initialize the tunnel metadata. However, it forgets to zero the unused rxhash fields. This could lead to...

Astra Linux - уязвимость в linux-5.10

In the Linux kernel, the following vulnerabilities have been resolved: crypto: krb5enc – Fix for async decryption skipping hash verification The krb5encdispatchdecrypt function sets req-base.complete as the skcipher callback. This means that when the skcipher completes asynchronously, it signals...

In the Linux kernel, the following vulnerability has been resolved: crypto: algifhash – fixed the double-free in hashaccept. If the accept2 function is called on the algifhash socket type with the MSGMORE flag set, and the cryptoahashimport fails, sk2 is freed. However, it is also freed in...

Astra Linux - уязвимость в python-ipaddress

The Lib/ipaddress.py module in Python up to version 3.8.3 incorrectly calculates hash values for the IPv4Interface and IPv6Interface classes. This may allow a remote attacker to cause a denial of service if an application relies on the performance of a dictionary containing IPv4Interface or...
