Astra Linux – Vulnerability in Qemu

A flaw was discovered in the implementation of the 9p passthrough filesystem 9pfs in QEMU. The 9pfs server did not prevent the opening of special files on the host side, potentially allowing a malicious client to escape from the exported 9p tree by creating and opening a device file in the shared...

Astra Linux – Vulnerability in Qemu

A flaw was discovered in the USB redirector device emulation of QEMU in versions prior to 6.1.0-rc2. This flaw occurs when dropping packets during a bulk transfer from a SPICE client, due to the packet queue being full. A malicious SPICE client could exploit this flaw to call the free function in...

Astra Linux – Vulnerability in connman

The client.c file in gdhcp within ConnMan, as of version 1.41, can be exploited by network-adjacent attackers who operate a crafted DHCP server. This exploitation can lead to a stack-based buffer overflow and a denial of service attack, resulting in the termination of the connman process...

Astra Linux – Vulnerability in Qemu

A use-after-free flaw was discovered in the MegaRAID emulator of QEMU. This issue occurs during the processing of SCSI I/O requests when the mptsasfreerequest function fails to dequeue the request object ‘req’ from the pending requests queue. This flaw allows a privileged guest user to crash the...

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

In the Linux kernel, the following vulnerabilities have been resolved: xhci: Properly handling isoc Babble and Buffer Overrun events. xHCI 4.9 explicitly prohibits making assumptions that the xHC has released its ownership of a multi-TRB TD when an error occurs in one of the early TRBs. However,...

Astra Linux – Vulnerability in Linux 5.10, Linux

In the Linux kernel, the following vulnerabilities have been resolved: misc/vmwvmci: fixed an infoleak in vmcihostdoreceivedatagram The struct vmcieventqp allocated by qpnotifypeer contains padding, which may carry uninitialized data to the user space, as observed by KMSAN: BUG: KMSAN:...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: cxl/pci: Fixed the issue where memory was disabled if the DVSEC CXL range did not match a CFMWS window. The Linux CXL subsystem is based on the assumption that HPA == SPA. That is, the host physical address HPA of the HDM decoder...

Astra Linux – Vulnerability in Linux, Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: scsi: core – Ensure that the LLD module reference count is set after the SCSI device is released. The SCSI host release is triggered when the SCSI device is freed. We must ensure that the low-level device driver module is not...

Astra Linux – Vulnerability in Qemu

A heap buffer overflow was discovered in the floppy disk emulator of QEMU up to version 6.0.0 inclusive. This issue could occur in the fdctrltransferhandler function in the hw/block/fdc.c file, during the processing of DMA read data transfers from the floppy drive to the guest system. A privilege...

Astra Linux – Vulnerability in Qemu

A heap-based buffer overflow was discovered in QEMU version 5.0.0 in the SDHCI device emulation support. This vulnerability could occur during a multi-block SDMA transfer using the sdhcisdmatransfermultiBlocks routine in the hw/sd/sdhci.c file. A malicious user or process could exploit this flaw ...

Astra Linux – Vulnerability in Firefox and Thunderbird

Relative URLs that start with three slashes were incorrectly parsed. The “path-traversal” /../ part in the path could be used to override the specified host. This could lead to security issues in websites. This vulnerability affects Firefox 120, Firefox ESR 115.5.0, and Thunderbird 115.5...

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 Linux

A flaw was discovered in the KVM’s AMD code, which handles SVM nested virtualization.
