Astra Linux – Vulnerability in Linux 5.10

A race condition was detected in the Linux kernel’s ebpf verifier between bpfmapupdateelem and bpfmapfreeze, due to a missing lock in the kernel/bpf/syscall.c file. In this flaw, a local user with special privileges capsysadmin or capbpf can modify the frozen mapped address space. This flaw affec...

Astra Linux – Vulnerability in exim4

Exim 4 before 4.94.2 allows exposure of file descriptors to an unintended control sphere, because rdainterpret uses a privileged pipe without the closeonexec flag...

Astra Linux – Vulnerability in Chromium

Inappropriate implementation in Extensions in Google Chrome prior to 115.0.5790.170 allowed an attacker who convinced a user to install a malicious extension to inject scripts or HTML into a privileged page via a crafted Chrome Extension. Chromium security severity: Medium...

Astra Linux – Vulnerability in Qemu

A flaw was discovered in qemu. A host privilege escalation issue was identified in the virtio-fs shared file system daemon, where a privileged guest user can create a device-specific special file in the shared directory and use it to gain read/write access to host devices...

Astra Linux – Vulnerability in Qemu

An integer overflow issue was identified in the vmxnet3 NIC emulator of QEMU for versions up to v5.2.0. This issue can occur if a guest provides invalid values for the rx/tx queue size or other NIC parameters. A privileged guest user may exploit this flaw to crash the QEMU process on the host,...

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

A flaw was discovered in the Netfilter subsystem of the Linux kernel. The xtu32 module failed to validate the fields within the xtu32 structure. This flaw allows a local privileged attacker to trigger an out-of-bounds read by setting the size fields with a value that exceeds the bounds of the...

Astra Linux – Vulnerability in Firefox

The documents incorrectly assumed a certain order of principal objects when determining whether we were loading an appropriately privileged principal. In certain circumstances, it might have been possible for a document to be loaded with a more privileged principal than intended. This vulnerabili...

Astra Linux – Vulnerability in Samba

A flaw was discovered in the Samba AD LDAP server. The AD DC database audit logging module can access values of LDAP messages freed by a preceding database module, leading to a use-after-free issue. This issue only occurs when certain privileged attributes are modified, such as userAccountControl...

Astra Linux – Vulnerability in edk2

Improper authentication in EDK II may allow a privileged user to potentially enable information disclosure through network access...

Astra Linux – Vulnerability in Chromium

Insufficient data validation in Extensions in Google Chrome prior to 120.0.6099.216 allowed an attacker in a privileged network position to install a malicious extension via a crafted HTML page. Chromium security severity: High...

Astra Linux – Vulnerability in Linux, Linux 5.10

A flaw was discovered in the Linux kernel’s implementation of RDMA over InfiniBand. An attacker with a privileged local account can leak kernel stack information by issuing commands to the /dev/infiniband/rdmacm device node. Although this access is unlikely to reveal sensitive user information, i...

Astra Linux – Vulnerability in Qemu

A use-after-free vulnerability was discovered in the LSI53C895A SCSI Host Bus Adapter emulation in QEMU. The flaw occurs during the processing of repeated messages to cancel the current SCSI request using the lsidomsgout function. This flaw allows a malicious privileged user within the guest to...

Astra Linux – Vulnerability in Firefox and Thunderbird

An attacker could have sent a message to the parent process, with the contents being used to index into a JavaScript object twice. This would lead to prototype pollution, and ultimately, attacker-controlled JavaScript would execute in the privileged parent process. This vulnerability affects...

Astra Linux – Vulnerability in Linux, Linux 5.10

It was discovered that there was a lack of CPU resources in the Linux kernel tracing module functionality in versions prior to 5.14-rc3. This issue occurred due to the way users utilize the trace ring buffer. Only privileged local users with the CAPSYSADMIN capability could exploit this flaw to...

Astra Linux – Vulnerability in Chromium

Inappropriate implementation of Omnibox in Google Chrome prior to version 99.0.4844.51 allowed an attacker with privileged network access to perform a man-in-the-middle attack through malicious network traffic. Chromium security severity: Low...

Astra Linux – Vulnerability in Qemu

A use-after-free vulnerability was discovered in the am53c974 SCSI host bus adapter emulation in QEMU in versions prior to 6.0.0, during the handling of the ‘Information Transfer’ command CMDTI. This flaw allows a privileged guest user to crash the QEMU process on the host, resulting in a denial ...

Astra Linux – Vulnerability in Linux, Linux 5.10

A kernel information leak flaw was identified in the scsiioctl function in drivers/scsi/scsiioctl.c within the Linux kernel. This flaw allows a local attacker with special user privileges CAPSYSADMIN or CAPSYSRAWIO to cause confidentiality issues...

Astra Linux – Vulnerability in grub2

A flaw was discovered in grub2, where its configuration file, known as grub.cfg, is created with the wrong permission set, allowing non-privileged users to read its contents. This represents a minor confidentiality issue, as those users could potentially access any encrypted passwords contained i...

Astra Linux – Vulnerability in glib2.0

A flaw was discovered in glib before version 2.63.6. Due to random charset aliases, pkexec can leak content from files owned by privileged users to unprivileged users under certain conditions...

Astra Linux – Vulnerability in Qemu

A flaw was discovered in the QXL display device emulation in QEMU. An integer overflow in the cursoralloc function can lead to the allocation of a small cursor object, followed by a subsequent heap-based buffer overflow. This flaw allows a malicious privileged guest user to crash the QEMU process...
