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

A flaw was discovered in the XFRM subsystem of the Linux kernel. The specific flaw occurs during the processing of state filters, which can lead to a read beyond the end of an allocated buffer. This flaw allows a local privileged CAPNETADMIN attacker to trigger an out-of-bounds read, potentially...

Astra Linux – Vulnerability in Linux

A out-of-bounds memory write flaw was discovered in the listdevices function within drivers/md/dm-ioctl.c in the Multi-device driver module of the Linux kernel before version 5.12. A bound check failure allows an attacker with special user CAPSYSADMIN privileges to gain access to out-of-bounds...

Astra Linux – Vulnerability in Qemu

A double-free vulnerability was identified in QEMU virtio devices virtio-gpu, virtio-serial-bus, virtio-crypto. The memreentrancyguard flag does not provide sufficient protection against reentrancy issues related to DMA operations. This vulnerability could allow a malicious privileged guest user ...

Astra Linux – Vulnerability in Python 3.11, Python 3.7

A issue was discovered in the CPython tempfile.TemporaryDirectory class, affecting versions 3.12.1, 3.11.7, 3.10.13, 3.9.18, 3.8.18, and earlier versions. The tempfile.TemporaryDirectory class would dereference symlinks during cleanup of permissions-related errors. This means that users who can...

Astra Linux – Vulnerability in Qemu

A out-of-bounds heap buffer access issue was identified in the ARM Generic Interrupt Controller emulator of QEMU, as of and including qemu 4.2.0 on the aarch64 platform. The issue arises because, when writing an interrupt ID to the controller’s memory area, it is not masked to be 4 bits wide. Thi...

Astra Linux – Vulnerability in Qemu

A flaw was discovered in the QXL display device emulation in QEMU. An integer overflow in the cursoralloc function can lead to the allocation of a small cursor object, followed by a subsequent heap-based buffer overflow. This flaw allows a malicious privileged guest user to crash the QEMU process...

Astra Linux – Vulnerability in glib2.0

A flaw was discovered in glib before version 2.63.6. Due to random charset aliases, pkexec can leak content from files owned by privileged users to unprivileged users under certain conditions...

Astra Linux – Vulnerability in Chromium

Insufficient data validation in Extensions in Google Chrome prior to 115.0.5790.170 allowed an attacker who convinced a user to install a malicious extension to inject scripts or HTML into a privileged page via a crafted Chrome Extension. Chromium security severity: Medium...

Astra Linux – Vulnerability in Firefox

Due to URL previews in the network panel of developer tools improperly storing URLs, query parameters could potentially be used to overwrite global objects in privileged code. This vulnerability affects Firefox versions earlier than 110...

Astra Linux – Vulnerability in Qemu

A reachable assertion issue was detected in the USB EHCI emulation code of QEMU. This issue can occur during the processing of USB requests due to improper handling of the DMA memory map. A malicious privileged user within the guest environment may exploit this flaw to send invalid USB requests,...

Astra Linux – Vulnerability in Ceph

A privilege escalation flaw was discovered in Ceph. Ceph-crash.service allows a local attacker to escalate privileges to root through a crash dump, thereby exposing privileged information...

Astra Linux – Vulnerability in Linux 5.10, Linux

A denial-of-service DOS issue was detected in the smb2ioctlqueryinfo function of the Linux kernel, within the fs/cifs/smb2ops.c Common Internet File System. This issue arises due to an incorrect return value from the memdupuser function. This flaw allows a local, privileged attacker with...

Astra Linux – Vulnerability in Qemu

An infinite loop flaw was discovered in the USB xHCI controller emulation of QEMU while calculating the length of the Transfer Request Block TRB Ring. This flaw allows a privileged guest user to halt the QEMU process on the host, resulting in a denial of service...

Astra Linux – Vulnerability in Firefox

In a non-standard configuration of Firefox, an integer overflow could have occurred due to network traffic possibly under the influence of a local unprivileged web page, resulting in an out-of-bounds write to privileged process memory. This bug only affects Firefox if a non-standard preference...

Astra Linux – Vulnerability in Firefox and Thunderbird

A compromised content process could have allowed malicious data to be stored in a PathRecording object, resulting in an out-of-bounds write operation. This led to a potentially exploitable crash in a privileged process. This vulnerability affects Firefox 118, Firefox ESR 115.3, and Thunderbird...

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

A flaw was discovered in the Netfilter subsystem of the Linux kernel. The nfnlosfaddcallback function did not validate the optnum field controlled by the user mode. This flaw allows a local privileged attacker with CAPNETADMIN privileges to trigger an out-of-bounds read, resulting in a system cra...

Astra Linux – Vulnerability in PostgresSQL 11

schemaelement defeats protective measures for search paths; It was discovered that certain database calls in PostgreSQL could allow an authenticated attacker with elevated database-level privileges to execute arbitrary code...

Astra Linux – Vulnerability in Redis

Redis is an open-source, in-memory database that persists data on disk. A user with sufficient privileges can create a malformed ACL selector, which, when accessed, triggers a server panic and subsequent denial of service. This issue exists in Redis version 7, before versions 7.2.6 and 7.4.1. Use...

Astra Linux – Vulnerability in Qemu

A use-after-free flaw was discovered in the MegaRAID emulator of QEMU. This issue occurs during the processing of SCSI I/O requests when the mptsasfreerequest function fails to dequeue the request object ‘req’ from the pending requests queue. This flaw allows a privileged guest user to crash the...

Astra Linux – Vulnerability in Firefox and Thunderbird

If an attacker were able to corrupt the methods of an Array object in JavaScript through prototype pollution, they could have executed JavaScript code under their control in a privileged context. This vulnerability affects Firefox ESR 91.9.1, Firefox 100.0.2, Firefox for Android 100.3.0, and...
