In the Linux kernel, the following vulnerability has been resolved: usb: gadget: fmassstorage: Fixed a potential integer overflow in the checkcommandsizeinblocks function. The checkcommandsizeinblocks function calculates the data size in bytes by shifting common-datasizefromcmnd by the block size...

Astra Linux – Vulnerability in glib2.0

A flaw was discovered in glib. This vulnerability allows for a heap buffer overflow and a denial-of-service attack through an integer overflow in GLib’s GIO GLib Input/Output escapebytestring function, when processing malicious file or remote filesystem attribute values...

Astra Linux – Vulnerability in freerdp3, freerdp2

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 found in Linux 5.10, Linux 6.1, Linux, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: fbmon: prevented division by zero in fbvideomodefromvideomode. The expression htotal vtotal can have a zero value during overflow.
