This security bulletin contains information about 3 vulnerabilities.
EUVDB-ID: #VU61672
Risk: Low
CVSSv3.1:
CVE-ID: CVE-2022-27666
CWE-ID:
CWE-122 - Heap-based Buffer Overflow
Exploit availability: Yes
DescriptionThe vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to a boundary error within IPsec ESP transformation code in net/ipv4/esp4.c and net/ipv6/esp6.c in Linux kernel. A local unprivileged user can pass specially crafted data to the system, trigger a heap-based buffer overflow and execute arbitrary code with elevated privileges.

EUVDB-ID: #VU61258
Risk: Low
CVSSv3.1:
CVE-ID: CVE-2021-4197
CWE-ID:
CWE-264 - Permissions, Privileges, and Access Controls
Exploit availability: No
DescriptionThe vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to missing permissions checks within the cgroups (control groups) functionality of Linux Kernel when writing into a file descriptor. A local low privileged process can trick a higher privileged parent process into writing arbitrary data into files, which can result in denial of service or privileges escalation.

CVE-ID: CVE-2021-20322
CWE-ID:
CWE-330 - Use of Insufficiently Random Values
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to gain access to sensitive information.
The vulnerability exists due to an error when processing received ICMP errors. A remote attacker can effectively bypass the source port UDP randomization to gain access to sensitive information.
