Astra Linux – Vulnerability in xorg-server

A use-after-free flaw was identified in the X.Org X server and Xwayland within the miSyncDestroyFence function. A client that sets up multiple fence triggers may trigger a use-after-free function pointer call. An attacker could connect to the X server to set up a fence and wait for it, then anoth...

Astra Linux – Vulnerability in xorg-server

A stack-based buffer overflow vulnerability was discovered in the X.Org X server and Xwayland. A mismatch between the X server’s requirements and the maximum font name length supported by the libXfont2 library can lead to a stack buffer overflow during font alias resolution. The X server allocate...

Astra Linux – Vulnerability in Chromium

Inappropriate implementations in Extensions in Google Chrome prior to 149.0.7827.53 allowed an attacker who convinced a user to install a malicious extension to perform privilege escalation through a crafted Chrome Extension. Chromium security severity: Low...

Astra Linux – Vulnerability in xorg-server

A vulnerability was discovered in X.Org. This security flaw arises because the XkbCopyNames function left a dangling pointer pointing to freed memory, allowing for out-of-bounds memory access during subsequent XkbGetKbdByName requests. This issue can lead to local privileges escalation on systems...

Astra Linux – Vulnerability in Linux 5.10

A out-of-bounds memory write flaw was discovered in the Linux kernel’s watchqueue event notification subsystem. This flaw can overwrite parts of the kernel state, potentially allowing a local user to gain privileged access or cause a denial of service on the system...

Astra Linux – Vulnerability found in Linux 5.10, Linux 5.15

A race condition was detected in the Linux kernel’s RxRPC network protocol, during the processing of RxRPC bundles. This issue arises due to the lack of proper locking when performing operations on an object. This could allow an attacker to escalate privileges and execute arbitrary code within th...

Astra Linux – Vulnerability in PostgresSQL 11

A late privilege drop in the REFRESH MATERIALIZED VIEW CONCURRENTLY operation in PostgreSQL allows an object creator to execute arbitrary SQL functions as the command issuer. This feature enables the owner of the materialized view to run SQL functions, thereby allowing for the safe refreshing of...

Astra Linux – Vulnerability in Linux, Linux 5.10

A use-after-free vulnerability was discovered in the Linux kernel, specifically in the drivers/net/hamradio module. This flaw allows a local attacker with user privileges to cause a denial of service DOS condition when the mkiss or sixpack device is detached, resulting in premature reclamation of...

Astra Linux – Vulnerability in Linux 5.10, Linux, Linux 5.15

A flaw related to the use of “free” in the Linux kernel’s integrated infrared receiver/transceiver driver was discovered in the way local users detach RC devices. This flaw could be exploited by local users to crash the system or potentially escalate their privileges on the system...

Astra Linux – Vulnerability in Intel Microcode

Improper isolation in some IntelR processors’ stream cache mechanism may allow an authenticated user to potentially enable privilege escalation through local access...

Astra Linux – Vulnerability in Chromium

Insufficient validation of untrusted input in Cast in Google Chrome prior to 149.0.7827.53 allowed an attacker on the local network segment to perform privilege escalation via a crafted HTML page. Chromium security severity: Low...

Astra Linux – Vulnerability in xorg-server

A vulnerability was discovered in X.Org. This security flaw occurs because the swap handler for the XTestFakeInput request of the XTest extension may corrupt the stack if GenericEvents with lengths greater than 32 bytes are sent through the XTestFakeInput request. This issue can lead to local...

Astra Linux – Vulnerability in libblockdev, udisks2

A Local Privilege Escalation LPE vulnerability was discovered in libblockdev. Typically, the “allowactive” setting in Polkit allows a physically present user to perform certain actions based on the session type. Due to the way libblockdev interacts with the udisks daemon, a “allowactive” user on ...

A out-of-bounds memory access vulnerability was discovered in the vmwgfx driver, located in the vmxgfx/vmxgfxkms.c file within the GPU component of the Linux kernel. The vulnerability affects device files such as '/dev/dri/renderD128 or Dxxx'. This flaw allows a local attacker with a user account...

Astra Linux – Vulnerability in zsh

In Zsh before version 5.8, attackers who were able to execute commands could regain privileges lost due to the --no-PRIVILEGED option. Zsh failed to overwrite the saved user ID, so the original privileges could be restored by executing MODULEPATH=/dir/with/module zmodload with a module that calls...
