The remote Redhat Enterprise Linux 8 host has packages installed that are affected by a vulnerability as referenced in the RHSA-2021:2724 advisory. The systemd packages contain systemd, a system and service manager for Linux, compatible with the SysV and LSB init scripts. It provides aggressive...

systemd: uncontrolled allocation on the stack in function unit_name_path_escape leads to crash

A flaw was found in systemd. The use of alloca function with an uncontrolled size in function unitnamepathescape allows a local attacker, able to mount a filesystem on a very long path, to crash systemd and the whole system by allocating a very large space in the stack. The highest threat from th...

It provides aggressive parallelism capabilities, uses socket and D-Bus activation for starting services, offers on-demand starting of daemons, and keeps track of processes...

A flaw was found in the USB redirector device (usb-redir) of QEMU. Small USB packets are combined into a single large transfer request to reduce the overhead and improve performance. The combined size of the bulk transfer is used to dynamically allocate a variable length array (VLA) on the stack without proper validation. Since the total size is not bounded a malicious guest could use this flaw to influence the array length and cause the QEMU process to perform an excessive allocation on the stack resulting in a denial of service.
