Astra Linux – Vulnerability in gzip, xz-utils

A arbitrary file writing vulnerability was discovered in the GNU gzip’s zgrep utility. When zgrep is applied to a file name chosen by the attacker e.g., a crafted file name, it can overwrite the content of the target file with an arbitrary file selected by the attacker. This flaw arises due to...

Astra Linux – Vulnerability in OpenLDAP

A vulnerability was discovered in openldap. This security flaw causes a null pointer dereference in the bermemallocx function...

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 Qemu

A flaw was discovered in the QEMU’s built-in VNC server during the processing of ClientCutText messages. The qemuclipboardrequest function can be accessed before vncservercuttextcaps is called, which gives a malicious authenticated VNC client the opportunity to initialize the clipboard peer. This...

Astra Linux – Vulnerability in Thunderbird, Firefox

Module load requests that failed were not checked to determine whether they had been cancelled, resulting in a use-after-free in ScriptLoadContext. This vulnerability affects Firefox 110, Thunderbird 102.8, and Firefox ESR 102.8...

Astra Linux – Vulnerability in Qemu

A out-of-bounds read flaw was discovered in the QXL display device emulation in QEMU. The qxlphys2virt function does not check the size of the structure pointed to by the guest physical address, potentially allowing it to read beyond the bounds of the bar space onto adjacent pages. A malicious...

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

In the Linux kernel, the following vulnerabilities have been resolved: proc: Fixed a UAF in procgetinode. Fixed a race condition between rmmod and the instantiation of /proc/XXX’s inode. The bug is that pde-procops does not belong to /proc; it belongs to a module. Therefore, dereferencing it afte...

Astra Linux – Vulnerability found in Linux 6.1, Linux 5.15

In the Linux kernel, the following vulnerabilities have been resolved: drm/amd/display: fixed a double-free issue during the unloading of the amdgpu module Flexible endpoints use DIGs from available inflexible endpoints; therefore, only the encoders of inflexible links need to be freed. Otherwise...

Astra Linux – Vulnerability in Xen

A issue was discovered in Xen through version 4.11.x, allowing users of x86 Intel HVM guest operating systems to obtain unintended read/write DMA access. This could potentially lead to a denial of service causing the host operating system to crash or result in privilege escalation. This issue...

Astra Linux – Vulnerability in Samba

A flaw was discovered in Samba, specifically in the vfsstreamsxattr module. In this module, uninitialized heap memory could be written into alternate data streams. This allows an authenticated user to read residual memory content, which may include sensitive data, resulting in an information...

Astra Linux – Vulnerability in Apache2

Malformed requests may cause the server to dereference a NULL pointer. This issue affects Apache HTTP Server 2.4.48 and earlier...

Astra Linux – Vulnerability in linux-astra-modules-5.4, linux-astra-modules-5.10, linux-astra-modules-5.15

The vulnerability of the pdplget function in the Linux-astra-modules kernel module is related to the assignment of a null pointer. Exploiting this vulnerability allows an attacker to cause a service failure...

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

In the Linux kernel, the following vulnerability has been resolved: iio: adc: at91-sama5d2adc: Fixed a potential use-after-free in the sama5d2adc driver. The at91adcinterrupt function can call the at91adctouchdatahandler function to initiate the processing via schedulework&st-touchst.workq. If we...

Astra Linux – Vulnerability in freerdp3, freerdp2

FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to version 3.22.0, the URBDRC client used server-supplied interface numbers as array indices without bounds checks, resulting in a out-of-bounds read in libusbudevselectinterface. This vulnerability has been fixed in version...

Astra Linux – Vulnerabilities in Linux 5.10, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: net: ipv6: unexport init-annotated seg6hmacinit EXPORTSYMBOL and init are a poor combination because the .init.text section is freed after initialization. As a result, modules cannot use symbols annotated with init. Access to a...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: In the net subsystem, for the dsa module, the microchip function has been updated to include a condition for scheduling the kszmibreadwork function. When the ksz module is installed or removed using the rmmod command, the kernel...

Astra Linux – Vulnerability in Linux 5.10

A flaw was discovered in the IPv6 module of the Linux kernel. The arg.result parameter was not used consistently in fib6rulelookup; sometimes rt6info was used, and other times fib6info. This issue was not accounted for in other parts of the code, where rt6info was expected to be used...

Astra Linux – Vulnerability in dnsmasq

A buffer overflow in the dnsmasq’s extractaddresses function allows an attacker to trigger a heap out-of-bounds read and crash by exploiting a malformed DNS response. This enables extractname to advance the pointer past the end of the record...

Astra Linux – Vulnerability in Qemu

A reentrancy issue related to DMA was discovered in the Tulip device emulation in QEMU. When Tulip reads from or writes to the rx/tx descriptor, or copies a rx/tx frame, it does not check whether the destination address is its own MMIO address. This can cause the device to trigger MMIO handlers...

Astra Linux – Vulnerability in Cairo

A issue was discovered in cairo 1.16.0. There is an infinite loop in the function arcerrornormalized in the file cairo-arc.c, which is related to arcmaxanglefortolerancenormalized...
