Astra Linux – Vulnerability in glibc

Calling getnetbyaddr or getnetbyaddrr with a configured nsswitch.conf that specifies the library’s DNS backend can lead to a situation where a zero-valued network is queried during operations in the GNU C Library versions 2.0 to 2.42. This could result in the leakage of stack contents to the...

Astra Linux – Vulnerability in grub2

A use-after-free vulnerability has been identified in the GNU GRUB Grand Unified Bootloader. The flaw occurs because the process that closes files improperly retains a memory pointer, leaving an invalid reference to a file system structure. An attacker could exploit this vulnerability to cause th...

Astra Linux – Vulnerability in grub2

A vulnerability has been identified in the GRUB2 bootloader’s normal command, posing an immediate Denial of Service DoS risk. This flaw is a Use-after-Free issue, caused by the fact that the normal command is not properly unregistered when the module is unloaded. An attacker who can execute this...

Astra Linux – Vulnerability found in Linux 6.12, Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: fs: ntfs3: fixed an infinite loop in attrloadrunsrange when there are inconsistencies in metadata. We have identified a bug in the ntfs3 file system where a malformed NTFS image can cause an infinite loop. This occurs when an...

Astra Linux – Vulnerability in xwayland, xorg-server

A flaw was discovered in the X.Org X server. This integer underflow vulnerability, specifically related to the handling of the XKB compatibility map, allows an attacker with local or remote X11 server access to trigger a buffer read overflow. This can lead to memory safety violations and...

Astra Linux – Vulnerability in xwayland, xorg-server

A flaw was discovered in the X.Org X server. This vulnerability, an out-of-bounds read, affects the handling of XKB X Keyboard Extension modifier maps. An attacker with access to the X11 server can exploit this by sending a malformed request, causing the server to read beyond its intended memory...

Astra Linux – Vulnerability in libheif

libheif is a decoder and encoder for HEIF and AVIF file formats. In versions 1.21.2 and earlier, a crafted 792-byte HEIF sequence file with samplesperchunk=0 in the stsc field could cause an unsigned integer underflow in the Chunk constructor mlastsample = 0 + 0 - 1 = UINT32MAX, causing all sampl...

Astra Linux – Vulnerability in qtimageformats-opensource-src

A buffer overflow in Nomacs v3.15.0 allows attackers to cause a denial of service DoS attack through a specially crafted MNG file...

Astra Linux – Vulnerability in Qemu

A flaw was discovered in QEMU. A specially crafted VMDK image could trigger an out-of-bounds read vulnerability, potentially leading to a 12-byte leak of sensitive information or a denial of service condition DoS...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerabilities have been resolved: net: openvswitch: removed the never-working support for setting nsh fields. The validation of the setnsh... action is completely incorrect. It involves the nshkeyputfromnlattr function, which is the same function used to...

Astra Linux – Vulnerability in GIMP

A flaw was discovered in GIMP. A heap-buffer-overflow vulnerability exists in the freadpascalstring function when processing a specially crafted Photoshop Document file. This occurs because the buffer allocated for a Pascal string is not properly null-terminated, leading to an out-of-bounds read...

Astra Linux – Vulnerability in TIF format

A flaw was discovered in the libtiff library. A remote attacker could exploit a signed integer overflow vulnerability in the putcontig8bitYCbCr44tile function by providing a specially crafted TIFF file. This flaw can lead to an out-of-bounds heap write due to incorrect memory pointer calculations...

Astra Linux – Vulnerability in libsoup3

A flaw was discovered in the asynchronous message queue handling of the libsoup library, which is widely used by GNOME and WebKit-based applications for managing HTTP/2 communications. When network operations are aborted at specific timing intervals, an internal message queue item may be freed...

Astra Linux – Vulnerability in vte2.91

GNOME VTE before version 0.76.3 allowed an attacker to cause a denial of service memory consumption through a window resizing escape sequence, a issue related to CVE-2000-0476...

Astra Linux – Vulnerability in libssh

A flaw was discovered in libssh. A remote attacker, by controlling client configuration files or knownhosts files, could create specific hostnames that, when processed by the matchpattern function, could lead to inefficient regular expression backtracking. This could cause timeouts and resource...

Astra Linux – Vulnerability in Network-Manager

A flaw was discovered in NetworkManager. When a system running NetworkManager with DEBUG logs enabled and an interface eth1 configured with LLDP enabled, a malicious user could inject a malformed LLDP packet. This would cause NetworkManager to crash, resulting in a denial of service...

Astra Linux – Vulnerability in freerdp3

FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to version 3.21.0, a client-side heap buffer overflow occurred in the gdiSurfaceToSurface path of the FreeRDP client due to a mismatch between destination rectangle clamping and the actual copy size. A malicious server can...

Astra Linux – Vulnerability in gpsd

There is an integer underflow vulnerability in the nextstate function in gpsd/packet.c in gpsd versions prior to the commit ffa1d6f40bca0b035fc7f5e563160ebb67199da7. When parsing a NAVCOM packet, the payload length is calculated using lexer-length = sizetc - 4, without checking whether the input...

Astra Linux – Vulnerability in GIMP

A flaw was discovered in GIMP. There is an integer overflow vulnerability when processing ICO image files, specifically in the icoreadinfo and icoreadicon functions. This issue arises because the size calculation for image buffers can exceed the limit due to a 32-bit integer evaluation, allowing...
