Astra Linux – Vulnerability in Linux 5.10

A flaw was discovered in the way the “flags” member of the new pipe buffer structure lacked proper initialization in the copypagetoiterpipe and pushpipe functions of the Linux kernel. As a result, these members could contain stale values. An unprivileged local user could exploit this flaw to writ...

Astra Linux – Vulnerability in Shadow

A vulnerability was discovered in Shadow 4.5. The newgidmap function part of shadow-utils is setuid, allowing an unprivileged user to be placed in a user namespace where setgroups2 is allowed. This enables an attacker to remove themselves from a supplementary group, potentially granting them acce...

Astra Linux – Vulnerability found in Linux 5.10, Linux 5.15

A buffer overflow vulnerability was discovered in the Netfilter subsystem of the Linux kernel. This issue could allow the leakage of both stack and heap addresses, and potentially enable Local Privilege Escalation to the root user through arbitrary code execution...

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

A use-after-free vulnerability exists in the netfilter component of the Linux kernel’s nftables module, which can be exploited to achieve local privilege escalation. The nftverdictinit function allows positive values to be used as drop errors within the hook verdict. As a result, the nfhookslow...

Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1, and Linux 5.15

A transient execution vulnerability in some AMD processors may allow an attacker to extract data from the L1D cache, potentially leading to the leakage of sensitive information across privileged boundaries...

Astra Linux – Vulnerability in xrdp

xrdp is an open-source RDP server. In versions up to 0.10.5, the session execution component did not properly handle an error during the privilege drop process. This improper privilege management could allow an authenticated local attacker to escalate privileges to root and execute arbitrary code...

Privilege escalation in the Graphics: WebRender component. This vulnerability was fixed in Firefox 152, Firefox ESR 140.12, Firefox ESR 115.37, Thunderbird 152, and Thunderbird 140.12...

Astra Linux – Vulnerability in Chromium

Inappropriate implementation in Extensions in Google Chrome prior to 149.0.7827.53 allowed a remote attacker who had compromised the renderer process to perform privilege escalation via a crafted HTML page. Chromium security severity: Low...

Astra Linux – Vulnerability in Apache2

A privilege management vulnerability in Apache HTTP Server 2.4.67 and earlier allows local .htaccess authors to read files with the privileges of the httpd user. This issue affects Apache HTTP Server versions from 2.4.67 onwards. Users are recommended to upgrade to version 2.4.68, which fixes thi...

Astra Linux – Vulnerability in Chromium

Insufficient validation of untrusted input in Extensions in Google Chrome prior to 149.0.7827.53 allowed a remote attacker who had compromised the renderer process to perform privilege escalation via a crafted HTML page. Chromium security severity: High...

Astra Linux – Vulnerability in xorg-server

A stack-based buffer overflow vulnerability was discovered in the X.Org X server and Xwayland. The X server has multiple stack buffers with a size of XkbMaxShiftLevel XkbNumKbdGroups, but the CheckKeyTypes function does not verify or limit non-canonical key types to XkbMaxShiftLevel. A client can...

Astra Linux – Vulnerability in xorg-server

A stack-based buffer overflow vulnerability was discovered in the X.Org X server and Xwayland. The XkbSetMapChecks function declares a fixed-size stack buffer, mapWidths256, indexed by key type index. The helper function CheckKeyTypes writes to this buffer at a position controlled by the client,...

Astra Linux – Vulnerability in Chromium

The inappropriate implementation of ImageCapture in Google Chrome prior to version 149.0.7827.53 allowed a remote attacker who had compromised the renderer process to perform privilege escalation through a crafted HTML page. Chromium security severity: Low...

Astra Linux – Vulnerability found in Linux 5.10, Linux 5.15

A use-after-free flaw was discovered in the Linux kernel’s netfilter, where a user triggers the nftpipaporemove function with an element without using NFTSETEXTKEYEND. This issue could allow a local user to crash the system or potentially escalate their privileges on the system...

Astra Linux – Vulnerability in Linux, Linux 5.10

A heap buffer overflow flaw was discovered in the IPsec ESP transformation code in net/ipv4/esp4.c and net/ipv6/esp6.c. This flaw allows a local attacker with normal user privileges to overwrite kernel heap objects and may lead to a local privilege escalation attack...

Astra Linux – Vulnerability in Linux 5.10, Linux

A flaw was discovered in the Linux kernel’s implementation of proxied virtualized TPM devices. In a system where virtualized TPM devices are enabled which is not the default setting, a local attacker can exploit this flaw to create a “use-after-free” condition, potentially allowing them to escala...

Astra Linux – Vulnerability in Linux, Linux 5.10

In various setup methods of the USB gadget subsystem, there is a possibility of unauthorized writing due to an incorrect flag check. This could lead to a local escalation of privileges without the need for additional execution privileges. User interaction is not required for exploitation. Product...

Astra Linux – Vulnerability in Linux

The overlayfs implementation in the Linux kernel failed to properly validate, regarding user namespaces, the setting of file capabilities on files in the underlying file system. Due to the combination of unprivileged user namespaces and a patch carried in the Ubuntu kernel that allows unprivilege...
