Astra Linux – Vulnerability in cups

OpenPrinting CUPS is an open-source printing system for Linux and other Unix-like operating systems. Prior to version 2.4.17, a network-attached attacker could send a crafted SNMP response to the CUPS SNMP backend, causing an out-of-bounds read of up to 176 bytes beyond the stack buffer. The leak...

Astra Linux – Vulnerability in libcaca

Astra Linux – Vulnerability in Qemu

A flaw was discovered in the USB redirector device usb-redir of QEMU. Small USB packets are combined into a single, large transfer request, in order to reduce overhead and improve performance. The combined size of the bulk transfer is used to dynamically allocate a variable length array VLA on th...

Astra Linux – Vulnerability in Qemu

An information disclosure vulnerability was discovered in the virtio vhost-user GPU device vhost-user-gpu of QEMU in versions up to and including 6.0. The flaw resides in the virglcmdgetcapsetinfo function in contrib/vhost-user-gpu/virgl.c, and can occur due to the reading of uninitialized memory...

Astra Linux – Vulnerability in Qemu

A vulnerability related to out-of-bounds read/write access was discovered in the USB emulator of QEMU in versions prior to 5.2.0. This issue occurs during the processing of USB packets from a guest, when the value of USBDevice’s ‘setuplen’ exceeds the value of ‘databuf4096’ in the dotokenin and...

Astra Linux – Vulnerability in Qemu

In QEMU versions up to 5.0.0, an assertion failure can occur during network packet processing. This issue affects the e1000e and vmxnet3 network devices. A malicious guest user/process could exploit this flaw to terminate the QEMU process on the host, resulting in a denial-of-service condition in...

Astra Linux – Vulnerability in Qemu

QEMU 5.0.0 has a use-after-free issue in the hw/usb/hcd-xhci.c file, as the return value of usbpacketmap is not checked...

Astra Linux – Vulnerability in Qemu

In QEMU 5.0.0, the file hw/usb/hcd-ohci.c contains a stack-based buffer over-read issue, caused by values obtained from the host controller driver...

Astra Linux – Vulnerability in Qemu

A out-of-bounds write flaw was discovered in the UAS USB-attached SCSI device emulation in QEMU in versions prior to 6.2.0-rc0. The device uses the guest-provided stream number without proper checking, which can lead to out-of-bounds access to the UASDevice-data3 and UASDevice-status3 fields. A...

Astra Linux – Vulnerability in libcaca

A flaw was discovered in libcaca. A buffer overflow in the export.c file, specifically in the exporttroff function, may lead to memory corruption and other potential issues...

Astra Linux – Vulnerability in Qemu

An integer overflow was detected in the QEMU implementation of VMWare’s paravirtual RDMA device in versions prior to 6.1.0. The issue occurs when handling a “PVRDMAREGDSRHIGH” write from the guest due to improper input validation. This flaw allows a privileged guest user to instruct QEMU to...

Astra Linux – Vulnerability in Qemu

A flaw was discovered in the QEMU implementation of VMWare’s paravirtual RDMA device. The issue arises when handling the “PVRDMACMDCREATEMR” command due to improper memory remapping mremap. This flaw allows a malicious guest to crash the QEMU process on the host. The greatest threat posed by this...

Astra Linux – Vulnerability in Cairo

A flaw was discovered in cairo’s image-compositor.c in all versions prior to 1.17.4. This flaw allows an attacker who can provide a crafted input file to cairo’s image-compositor for example, by convincing a user to open a file in an application that uses cairo, or if an application uses cairo on...

Astra Linux – Vulnerability in OpenLDAP

A flaw was discovered in OpenLDAP before version 2.4.57, which led to a crash in the slapd process during control handling of the Values Return Filter. This caused a denial of service attack, involving double-free operations and out-of-bounds reads...

Astra Linux – Vulnerability in OpenLDAP

A flaw was discovered in OpenLDAP before version 2.4.57, which led to a double-free and slapd crash during the saslAuthzTo process, resulting in a denial of service...

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 – Vulnerabilities in Linux 5.10, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: nbd: The function genlunregisterfamily is called first in nbdcleanup. Otherwise, there may be a race between the removal of the module and the handling of the netlink command, which can lead to an oops as shown below: BUG: Kernel...
