Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: openrisc: Fix jumplabel smp syncing The original commit, 8c30b0018f9d “openrisc: Add jump label support”, copied from arm64 and did not properly account for how icache invalidation operates on remote cores in OpenRISC. On OpenRIS...

Astra Linux – Vulnerability in libcaca

libcaca is a color ASCII art library. In versions 0.99.beta20 and earlier, a integer overflow vulnerability in libcaca’s canvas import functionality allowed attackers to perform a controlled heap out-of-bounds write attack by providing a crafted “caca” format file. Depending on the build...

Astra Linux – Vulnerability in Linux, Linux 5.10

A use-after-free vulnerability was discovered in the rtsxusbmsdrvremove function in the drivers/memstick/host/rtsxusbms.c file within the memstick module of the Linux kernel. In this flaw, a local attacker with user privileges could compromise the confidentiality of system resources. This...

Astra Linux – Vulnerability in cups

OpenPrinting CUPS is an open-source printing system for Linux and other Unix-like operating systems. In versions 2.4.8 and earlier, when starting the cupsd server with a Listen configuration item pointing to a symbolic link, the cupsd process could perform arbitrary chmod operations on the target...

Astra Linux – Vulnerability in cups

OpenPrinting CUPS is an open-source printing system for Linux and other Unix-like operating systems. In versions 2.4.12 and earlier, when the AuthType is set to anything other than Basic, if the request contains an Authorization: Basic ... header, the password is not checked. This leads to...

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 Python 3.11, Python 3.7

A vulnerability has been identified in the CPython venv module and CLI. This vulnerability arises from improper quoting of path names when creating a virtual environment. As a result, attackers can inject commands into the virtual environment “activation” scripts e.g., using “source...

Astra Linux – Vulnerability in Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: bpf: Fixed a UAF Use-After-Free issue caused by a race between btftrygetmodule and loadmodule. While working on code to populate the BTF IDs for modules during their initialization, I noticed that by the time the initialization...

Astra Linux – Vulnerability in Qemu

A issue was discovered in QEMU versions 7.1.0 through 8.2.1. In hw/pci/pciesriov.c, the registervfs function does not set NumVFs to PCISRIOVTOTALVF, resulting in improper interaction with hw/nvme/ctrl.c...

Astra Linux – Vulnerability found in Linux 5.10, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: dmaengine: sf-pdma: Added multithread support for a DMA channel. When we obtain a DMA channel and attempt to use it across multiple threads, it can lead to errors and cause the system to hang. bash % echo 64...

Astra Linux – Vulnerability in libxml2

Uncontrolled recursion occurs during XPath evaluation in libxml2, including in versions up to and including 2.9.14. This allows a local attacker to cause a stack overflow through crafted expressions. The XPath processing functions xmlXPathRunEval, xmlXPathCtxtCompile, and xmlXPathEvalExpr reset t...

Astra Linux – Vulnerability in Linux

In the Linux kernel, the following vulnerability has been resolved: drm/meson: fixed the crash that occurs during shutdown when the component is not probed. When the main component is not probed—for example, when the dw-hdmi module is not yet loaded or in a probe defer state—the following crash...

Astra Linux – Vulnerability in Qemu

The ethgetgsotype function in net/eth.c in QEMU 4.2.1 allows guest OS users to trigger an assertion failure. A guest can crash the QEMU process by sending packet data that lacks a valid Layer 3 protocol...

Astra Linux – Vulnerability in Qemu

Integer overflows and buffer overflows were identified in the ACPI Error Record Serialization Table ERST device of QEMU, within the readerstrecord and writeerstrecord functions. Both issues may allow the guest to exceed the host buffer allocated for the ERST memory device. A malicious guest could...

Astra Linux – Vulnerability in Ansible

A flaw was discovered in Ansible’s amazon.aws collection when using the towercallback parameter from the amazon.aws.ec2instance module. This flaw allows an attacker to exploit the issue, as the module handles the parameter insecurely, resulting in the password being leaked in the logs...

Astra Linux – Vulnerability in Qemu

It was found that the patch for CVE-2020-17380/CVE-2020-25085 is ineffective. As a result, QEMU becomes vulnerable to out-of-bounds read/write access issues that were previously identified in the SDHCI controller emulation code. This flaw allows a malicious privileged attacker to crash the QEMU...

Astra Linux – Vulnerability in libxml2

The vulnerability of the Libxml2 library is related to pointer dereferencing errors. Exploiting this vulnerability allows an attacker to cause a service failure...

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 cups

The vulnerability of the scanps function on the CUPS printing server is related to pointer arithmetic errors. Exploiting this vulnerability allows an attacker to cause service failures...
