| DATE | CVE | VULNERABILITY TITLE | RISK |
|---|---|---|---|
| 2021-06-12 | CVE-2021-32549 | Link Following vulnerability in Canonical Ubuntu Linux It was discovered that read_file() in apport/hookutils.py would follow symbolic links or open FIFOs. | 2.1 |
| 2021-06-12 | CVE-2021-32550 | Link Following vulnerability in Canonical Ubuntu Linux It was discovered that read_file() in apport/hookutils.py would follow symbolic links or open FIFOs. | 2.1 |
| 2021-06-12 | CVE-2021-32551 | Link Following vulnerability in Canonical Ubuntu Linux It was discovered that read_file() in apport/hookutils.py would follow symbolic links or open FIFOs. | 2.1 |
| 2021-06-12 | CVE-2021-32552 | Link Following vulnerability in Canonical Ubuntu Linux It was discovered that read_file() in apport/hookutils.py would follow symbolic links or open FIFOs. | 2.1 |
| 2021-06-12 | CVE-2021-32553 | Link Following vulnerability in multiple products It was discovered that read_file() in apport/hookutils.py would follow symbolic links or open FIFOs. | 2.1 |
| 2021-06-12 | CVE-2021-32554 | Link Following vulnerability in Canonical Ubuntu Linux It was discovered that read_file() in apport/hookutils.py would follow symbolic links or open FIFOs. | 2.1 |
| 2021-06-12 | CVE-2021-32555 | Link Following vulnerability in Canonical Ubuntu Linux It was discovered that read_file() in apport/hookutils.py would follow symbolic links or open FIFOs. | 2.1 |
| 2021-06-04 | CVE-2021-3489 | Out-of-bounds Write vulnerability in multiple products The eBPF RINGBUF bpf_ringbuf_reserve() function in the Linux kernel did not check that the allocated size was smaller than the ringbuf size, allowing an attacker to perform out-of-bounds writes within the kernel and therefore, arbitrary code execution. | 7.2 |
| 2021-06-04 | CVE-2021-3490 | Out-of-bounds Write vulnerability in multiple products The eBPF ALU32 bounds tracking for bitwise ops (AND, OR and XOR) in the Linux kernel did not properly update 32-bit bounds, which could be turned into out of bounds reads and writes in the Linux kernel and therefore, arbitrary code execution. | 7.2 |
| 2021-06-04 | CVE-2021-3491 | Out-of-bounds Write vulnerability in multiple products The io_uring subsystem in the Linux kernel allowed the MAX_RW_COUNT limit to be bypassed in the PROVIDE_BUFFERS operation, which led to negative values being usedin mem_rw when reading /proc/<PID>/mem. | 7.2 |
