Astra Linux – Vulnerability in Linux, Linux 5.10

A flaw after-free usage in the function scosocksendmsg of the Linux kernel’s HCI subsystem was discovered. This flaw allows a privileged local user to exploit it to crash the system or escalate their privileges on the system. This flaw triggers a race condition when the user calls ioct...

Astra Linux – Vulnerability in Samba

A flaw was discovered in the way Samba maps domain users to local users. An authenticated attacker could exploit this flaw to cause potential privilege escalation...

Astra Linux – Vulnerability in Chromium

Inappropriate implementation in Enterprise in Google Chrome prior to 149.0.7827.53 allowed a local attacker to perform privilege escalation via physical access to the device. Chromium security severity: Low...

Astra Linux – Vulnerability in busybox

A flaw was discovered in BusyBox. This vulnerability allows an attacker to modify files outside of the intended extraction directory by creating a malicious tar archive containing unvalidated hardlink or symlink entries. If the tar archive is extracted with elevated privileges, this flaw can lead...

Astra Linux – Vulnerability in libcap2

A flaw was discovered in libcap. A local unprivileged user can exploit a Time-of-check-to-time-of-use TOCTOU race condition in the capsetfile function. This allows an attacker with write access to a parent directory to redirect file capability updates to a file controlled by the attacker. By doin...

Astra Linux – Vulnerability found in Linux 5.10, Linux 5.15

A use-after-free vulnerability in the Linux Kernel’s iouring subsystem can be exploited to achieve local privilege escalation. Sending a iouring cancel poll request with a linked timeout can lead to a Use-after-Free UAF in a hrtimer mechanism. We recommend upgrading to the latest version of the...

Astra Linux – Vulnerability in Systemd

Before version 247, systemd does not properly prevent local privilege escalation for certain Sudo configurations. For example, plausible sudoers files may allow the execution of the “systemctl status” command. Specifically, systemd does not set LESSSECURE to 1, allowing other programs to be...

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

Incorrect verifier pruning in the BPF module of the Linux kernel version 5.4 and above leads to unsafe code paths being incorrectly marked as safe. This results in arbitrary read/writes to kernel memory, lateral privilege escalation, and container escapes...

Astra Linux – Vulnerability in xorg-server

A vulnerability was discovered in X.Org. This security flaw arises because the handler for the ScreenSaverSetAttributes request may write to memory after it has been freed. This issue can lead to local privileges escalation on systems where the X server is running with privileged access, and may...

Astra Linux – Vulnerability in Intel Microcode

In some IntelR XeonR processor memory controller configurations when using IntelR SGX, there is a check for improper conditions that may allow a privileged user to potentially enable privilege escalation through local access...

Astra Linux – Vulnerability in Mariadb 10.3

Vulnerability in the MySQL Client product of Oracle MySQL component: Client: mysqldump. The supported versions affected are 8.0.0–8.0.41, 8.4.0–8.4.4, and 9.0.0–9.2.0. This vulnerability is difficult to exploit; it allows low-privilege attackers with network access via multiple protocols to...

Astra Linux – Vulnerability in Intel Microcode

In some IntelR processors, the incorrect order of behavior during the transition between the executive monitor and the SMI transfer monitor STM may allow a privileged user to potentially enable privilege escalation through local access...

Astra Linux – Vulnerability in ofono

oFono SimToolKit Heap-based Buffer Overflow Privilege Escalation Vulnerability. This vulnerability allows local attackers to execute arbitrary code on affected installations of oFono. An attacker must first obtain the ability to execute code on the target modem in order to exploit this...

Astra Linux – Vulnerability in Linux

A buffer overflow attack in fbcon in the Linux kernel before version 5.9.7 could be exploited by local attackers to read privileged information or potentially cause the kernel to crash. This issue is identified as CID-3c4e0dff2095. This vulnerability arises because the KDFONTOPCOPY function in...

Astra Linux – Vulnerability in Thunderbird

In SkRegion.cpp, there is a potential out-of-bounds write due to an integer overflow. This could lead to a local privilege escalation without the need for additional execution privileges. User interaction is not required for exploitation...

Astra Linux – Vulnerability in Firefox

Privilege escalation in the Application Update component. This vulnerability was fixed in Firefox 151 and Thunderbird 151...

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

In the Linux kernel up to version 6.3.1, a use-after-free issue in Netfilter’s nftables module arises when processing batch requests. This allows unprivileged local users to obtain root privileges. The issue occurs due to improper handling of anonymous sets...

Astra Linux – Vulnerability in libndp

A vulnerability was discovered in libndp. This flaw allows a local malicious user to trigger a buffer overflow in NetworkManager, by sending a malformed IPv6 router advertisement packet. This issue occurred because libndp did not properly validate the route length information...

Astra Linux – Vulnerability in Thunderbird, Firefox

The WebChannel API, which is used to transfer various types of information between processes, did not check the identity of the sender. Instead, it accepted the identity of the sender without verification. This could lead to privilege escalation attacks. This vulnerability has been fixed in Firef...
