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

In the Linux kernel, the following vulnerability has been resolved: sched: schcake: Fixed the logic for accounting bulk flows in order to ensure host fairness. In schcake, we keep track of the number of active bulk flows per host. This is done when running in the dst/src host fairness mode, which...

Astra Linux – Vulnerability in connman

The client.c file in gdhcp within ConnMan, as of version 1.41, can be exploited by network-adjacent attackers who operate a crafted DHCP server. This exploitation can lead to a stack-based buffer overflow and a denial of service attack, resulting in the termination of the connman process...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: ICMP messages are rate-limited. After the committed issues, the two rate limiters are applied in this order: 1 Host-wide rate limit icmpglobalallow 2 Per-destination rate limit based on inetpeer To avoid side-channel attacks, we...

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

In the Linux kernel, the following vulnerabilities have been resolved: xhci: Properly handling isoc Babble and Buffer Overrun events. xHCI 4.9 explicitly prohibits making assumptions that the xHC has released its ownership of a multi-TRB TD when an error occurs in one of the early TRBs. However,...

Astra Linux – Vulnerability in docker.io

Moby is an open-source project created by Docker to enable software containerization. A bug was discovered in Moby Docker Engine where attempting to copy files using docker cp into a specially crafted container can result in changes to Unix file permissions for existing files in the host’s...

Astra Linux – Vulnerability in Qemu

Integer overflows and buffer overflows were identified in the ACPI Error Record Serialization Table ERST device of QEMU, within the readerstrecord and writeerstrecord functions. Both issues may allow the guest to exceed the host buffer allocated for the ERST memory device. A malicious guest could...

Astra Linux – Vulnerability in Flatpak

Flatpak is a Linux application sandboxing and distribution framework. Prior to version 1.16.4, the caching mechanism for ld.so removed outdated cache files without properly checking whether the app’s control over the path to the outdated cache was valid within the cache directory. This allowed...

Astra Linux – Vulnerability in Linux 5.10, Linux

In the Linux kernel, the following vulnerabilities have been resolved: mmc: mxcmmc: Fix the return value check in mmcaddhost. mmcaddhost may return an error. If we ignore its return value, the memory allocated by mmcallochost will be leaked, leading to a kernel crash due to the removal of devices...

Astra Linux – Vulnerability in containerd-app

Containerd is an open-source container runtime. Versions 1.7.28 and below, 2.0.0-beta.0 through 2.0.6, 2.1.0-beta.0 through 2.1.4, and 2.2.0-beta.0 through 2.2.0-rc.1 contain a bug in the CRI Attach implementation, where a user may exhaust memory on the host due to goroutine leaks. This issue has...

Astra Linux – Vulnerability in Containerd

Containerd is a container runtime that is available as a daemon for Linux and Windows. A bug was discovered in Containerd prior to versions 1.6.1, 1.5.10, and 1.14.12. In these versions, containers launched through Containerd’s CRI implementation on Linux, with a specially crafted image...

Astra Linux – Vulnerability in Linux 5.10, Linux

In the Linux kernel, the following vulnerability has been resolved: drm/mipi-dsi: Detaching devices when removing the host Whenever the MIPI-DSI host is unregistered, the code for mipidsihostunregister loops through every device currently found on that bus and will unregister them. However, it do...

Astra Linux – Vulnerability in Qemu

A flaw was discovered in the implementation of the 9p passthrough filesystem 9pfs in QEMU. The 9pfs server did not prevent the opening of special files on the host side, potentially allowing a malicious client to escape from the exported 9p tree by creating and opening a device file in the shared...

Astra Linux – Vulnerability in Linux 5.10, Linux

In the Linux kernel, the following vulnerabilities have been resolved: mmc: alcor: fixed the return value check in mmcaddhost The mmcaddhost function may return an error. If we ignore its return value, the memory allocated in mmcallochost will be leaked, leading to a kernel crash due to the remov...

Astra Linux – Vulnerability in Linux 5.10, Linux

In the Linux kernel, the following vulnerabilities have been resolved: xhci: Fixed null pointer dereferencing when the host dies. Ensure that xhcifreedev and xhcikillendpointurbs do not race with each other, and thus avoid null pointer dereferencing when the host suddenly dies. The USB core may...

Astra Linux – Vulnerability in Twisted

Twisted is an event-based framework for internet applications. It was introduced with version 0.9.4. At that time, when the host header did not match a configured host using twisted.web.vhost.NameVirtualHost, a “NoResource” resource would be returned. This caused the Host header to be rendered...

Astra Linux – Vulnerability in Firefox and Thunderbird

Relative URLs that start with three slashes were incorrectly parsed. The “path-traversal” /../ part in the path could be used to override the specified host. This could lead to security issues in websites. This vulnerability affects Firefox 120, Firefox ESR 115.5.0, and Thunderbird 115.5...

Astra Linux – Vulnerability in Linux

A flaw was discovered in the KVM’s AMD code, responsible for supporting SVM nested virtualization. The flaw occurs during the processing of the VMCB virtual machine control block provided by the L1 guest, which is used to spawn or handle a nested guest L2. Due to improper validation of the “intct...

Astra Linux – Vulnerability in glibc

A flaw has been identified in glibc. In an extremely rare situation, the getaddrinfo function may access memory that has been freed, resulting in an application crash. This issue is only exploitable when a NSS module implements only the nssgethostbyname2r and nssgetcanonnamer hooks without...

Astra Linux – Vulnerability in Containerd

Containerd is a container runtime. A bug was discovered in containerd versions prior to 1.4.8 and 1.5.4, where pulling and extracting a specially crafted container image could result in changes to Unix file permissions for existing files in the host’s filesystem. Changes to file permissions could...
