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 5.10

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

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 bind9

It is possible to create a zone such that certain queries to it will generate responses containing numerous records in the Additional section. An attacker sending multiple such queries can cause either the authoritative server or an independent resolver to use excessive resources to process the...

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 – Vulnerability in Firefox

Under certain circumstances, calling the bind function might result in an incorrect realm being assigned. 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: usb: gadget: frndis: Refactor the bind path to use free After a bind/unbind cycle, the rndis-notifyreq remains stale. If a subsequent bind fails, the unified error handling mechanism attempts to free this stale request. This lead...

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

In the Linux kernel, the following vulnerability has been resolved: iommusvabinddevice: This function should return either a device handle for binding SVA data, or an ERRPTR value in error cases. Existing drivers idxd and uacce only check the return value using ISERR. This could potentially lead ...

Astra Linux – Vulnerability in bind9

In BIND 9.3.0 - 9.11.35, 9.12.0 - 9.16.21, and versions 9.9.3-S1 - 9.11.35-S1 and 9.16.8-S1 - 9.16.21-S1 of the BIND Supported Preview Edition, as well as release version 9.17.0 - 9.17.18 of the BIND 9.17 development branch, exploiting broken authoritative servers using a flaw in response...

Astra Linux – Vulnerability in bind9

Every named instance configured to run as a recursive resolver maintains a cache database that holds the responses to the queries it has recently sent to authoritative servers. The size limit for that cache database can be configured using the max-cache-size statement in the configuration file; i...

Astra Linux – Vulnerability in bind9

The code that processes control channel messages sent to named recursively calls certain functions during packet parsing. The recursion depth is limited only by the maximum acceptable packet size; depending on the environment, this may cause the packet-parsing code to run out of available stack...

Astra Linux – Vulnerability in Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: In usbnet, there was a flaw where unregisternetdev was called before unbind. The commit with the commit ID 2c9d6c2b871d “usbnet: run unbind before unregisternetdev” was intended to fix a use-after-free issue when disconnecting US...

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 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 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...

Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: usb: gadget: fhid: The initialization of move lists and spinlocks has been moved from bind to alloc. There was an issue when you performed the following actions: - Configured and bound a hid gadget. - Opened /dev/hidg0. - Used th...
