"Description": "This update upgrades shim to version 15.7-alt3. \nSecurity Fix(es):\n\n * BDU:2022-03372: Уязвимость функции grub_net_recv_ip4_packets программы-загрузчика операционных систем Grub, позволяющая нарушителю выполнить произвольный код путем отправки специально сформированных IP-пакетов\n\n * CVE-2022-28733: Integer underflow in grub_net_recv_ip4_packets; A malicious crafted IP packet can lead to an integer underflow in grub_net_recv_ip4_packets() function on rsm-\u003etotal_len value. Under certain circumstances the total_len value may end up wrapping around to a small integer number which will be used in memory allocation. If the attack succeeds in such way, subsequent operations can write past the end of the buffer.\n\n * CVE-2022-28737: There's a possible overflow in handle_image() when shim tries to load and execute crafted EFI executables; The handle_image() function takes into account the SizeOfRawData field from each section to be loaded. An attacker can leverage this to perform out-of-bound writes into memory. Arbitrary code execution is not discarded in such scenario.",
