| DATE | CVE | VULNERABILITY TITLE | RISK |
|---|---|---|---|
| 2020-07-29 | CVE-2020-15707 | Integer Overflow or Wraparound vulnerability in multiple products Integer overflows were discovered in the functions grub_cmd_initrd and grub_initrd_init in the efilinux component of GRUB2, as shipped in Debian, Red Hat, and Ubuntu (the functionality is not included in GRUB2 upstream), leading to a heap-based buffer overflow. | 6.4 |
| 2020-07-29 | CVE-2020-15706 | Use After Free vulnerability in multiple products GRUB2 contains a race condition in grub_script_function_create() leading to a use-after-free vulnerability which can be triggered by redefining a function whilst the same function is already executing, leading to arbitrary code execution and secure boot restriction bypass. | 6.4 |
| 2020-07-29 | CVE-2020-15705 | Improper Verification of Cryptographic Signature vulnerability in multiple products GRUB2 fails to validate kernel signature when booted directly without shim, allowing secure boot to be bypassed. | 6.4 |
| 2019-06-19 | CVE-2019-11478 | Resource Exhaustion vulnerability in multiple products Jonathan Looney discovered that the TCP retransmission queue implementation in tcp_fragment in the Linux kernel could be fragmented when handling certain TCP Selective Acknowledgment (SACK) sequences. | 7.5 |
| 2019-06-19 | CVE-2019-11477 | Integer Overflow or Wraparound vulnerability in multiple products Jonathan Looney discovered that the TCP_SKB_CB(skb)->tcp_gso_segs value was subject to an integer overflow in the Linux kernel when handling TCP Selective Acknowledgments (SACKs). | 7.5 |
