Astra Linux – Vulnerabilities in unbound, bind9, and dnsmasq

Certain aspects of the DNS protocol’s DNSSEC mechanism described in RFC 4033, 4034, 4035, 6840, and related RFCs allow remote attackers to cause a denial of service attack by manipulating one or more DNSSEC responses. This issue is known as the “KeyTrap” problem. One of the concerns is that, when...

Astra Linux – Vulnerability in Ansible

A flaw was discovered in Ansible Engine, affecting versions 2.7.x before 2.7.17, 2.8.x before 2.8.11, and 2.9.x before 2.9.7. It also affects Ansible Tower in versions 3.4.5 and 3.5.5, as well as 3.6.3, when the ldapattr and ldapentry community modules are used. This issue exposes the LDAP bind...

Astra Linux – Vulnerability in bind9

By spoofing the target resolver with responses that have a malformed EdDSA signature, an attacker can trigger a small memory leak. It is possible to gradually erode the available memory to the point where named crashes occur due to lack of resources...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: In isotp.bind, there is a need to check the CAN address family. A missing check was added to prevent binds that use a non-AFCAN address family. Syzbot created some code that correctly determined the appropriate size of the sockad...

Astra Linux – Vulnerability in bind9

BIND servers are vulnerable if they are running an affected version and are configured to use GSS-TSIG features. In a configuration that uses BIND’s default settings, the vulnerable code path is not exposed. However, a server can become vulnerable by explicitly setting valid values for the...

Astra Linux – Vulnerability in Linux

The net/nfc/llcpsock.c file in the Linux kernel before version 5.12.10 allowed local unprivileged users to cause a denial of service by making a getsockname call after a certain type of failure in a bind call. This vulnerability results in NULL pointer dereferencing and other bugs...

Astra Linux – Vulnerability found in Linux 5.10, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: can: isotp: sanitize CAN ID checks in isotpBind. Syzbot created an environment that led to a state machine status that cannot be reached with a compliant CAN ID address configuration. The provided address information consisted of...

Astra Linux – Vulnerability in bind9

By flooding the target resolver with queries that exploit this flaw, an attacker can significantly impair the resolver’s performance, effectively denying legitimate clients access to the DNS resolution service...

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

In the Linux kernel, the following vulnerability has been resolved: USB: Gadget: fncm: Fixed UAF Use-After-Free in the ncm object after re-binding after a USB EP transport error When the ncm function is working, the usb0 interface is stopped due to a link failure. In this case, the ethstop functi...

Astra Linux – Vulnerability in Firefox

Under certain circumstances, calling the bind function might result in an incorrect realm being set. This could create a vulnerability related to JavaScript-implemented sandboxes, such as SES. This vulnerability affects Firefox for Android 112, Firefox 112, and Focus for Android 112...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: net: sched: clsu32: Undo tcfbindfilter if u32replacehwknode When u32replacehwknode fails, we need to undo the tcf BindFilter operation performed at u32setparms...

Astra Linux – Vulnerability in bind9

In BIND 9.0.0 - 9.11.29, 9.12.0 - 9.16.13, and versions BIND 9.9.3-S1 - 9.11.29-S1 and 9.16.8-S1 - 9.16.13-S1 of the Supported Preview Edition, as well as release versions 9.17.0 - 9.17.11 of the BIND 9.17 development branch, when a vulnerable version of named receives a query for a record that...

Astra Linux – Vulnerabilities in unbound, bind9, and dnsmasq

The “Closest Encloser Proof” aspect of the DNS protocol as described in RFC 5155, when the guidance provided in RFC 9276 is skipped enables remote attackers to cause a denial of service resulting in high CPU usage for SHA-1 calculations through DNSSEC responses during a random subdomain attack,...

Astra Linux – Vulnerability in Linux

An out-of-bounds memory access flaw was discovered in the x25bind function in the net/x25/afx25.c file within the Linux kernel version v5.12-rc5. A failure in the bounds check allows a local attacker with a user account on the system to access out-of-bounds memory, resulting in a system crash or...

Astra Linux – Vulnerability in bind9

If a BIND resolver performs DNSSEC validation and encounters a maliciously crafted zone, the resolver may consume excessive CPU resources. Authoritative-only servers are generally unaffected, although there are circumstances where authoritative servers may make recursive queries see:...

Astra Linux – Vulnerability in bind9

By spoofing the target resolver with responses that have a malformed ECDSA signature, an attacker can trigger a small memory leak. It is possible to gradually erode the available memory to the point where named crashes occur due to lack of resources...

Astra Linux – Vulnerability in bind9

In BIND 9.8.5 - 9.8.8, 9.9.3 - 9.11.29, 9.12.0 - 9.16.13, and versions of BIND 9 Supported Preview Edition such as 9.9.3-S1 - 9.11.29-S1 and 9.16.8-S1 - 9.16.13-S1, as well as the release version 9.17.0 - 9.17.11 of the BIND 9.17 development branch, when a vulnerable version of named receives a...

Astra Linux – Vulnerability in bind9

Resolver caches and authoritative zone databases that hold a significant number of Resource Records for the same hostname of any RTYPE may experience degraded performance as content is added or updated, as well as when handling client queries for this name. This issue affects BIND 9 versions 9.11...

Astra Linux – Vulnerability in bind9

If a server hosts a zone containing a “KEY” Resource Record, or if a resolver validates a “KEY” Resource Record from a DNSSEC-signed domain in its cache, a client can exhaust resolver CPU resources by sending a stream of SIG0 signed requests. This issue affects BIND 9 versions 9.0.0 through...

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

In the Linux kernel, the following vulnerability has been resolved: drm/mediatek: Cleaning up a dangling pointer on the bind error path The mtkdrmBind function may fail, in which case drmdevPut is called, destroying the drmdevice object. However, a pointer to that object was still being held by t...
