Description
This security bulletin contains information about 9 vulnerabilities.
1) Permissions, Privileges, and Access Controls (CVE-ID: CVE-2022-24769)
CWE-ID: CWE-264 - Permissions, Privileges, and Access Controls
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:L/VA:L/SC:N/SI:N/SA:N/E:U/U:Green
The vulnerability allows a remote attacker to escalate privileges on the system.
The vulnerability exists due to containers are incorrectly started with non-empty inheritable Linux process capabilities, which leads to security restrictions bypass and privilege escalation.
2) Use-after-free (CVE-ID: CVE-2021-4083)
CWE-ID: CWE-416 - Use After Free
CVSSv4: CVSS:4.0/AV:L/AC:L/AT:P/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to a use-after-free error within the Linux kernel's garbage collection for Unix domain socket file handlers. A local user can call close() and fget() simultaneously and can potentially trigger a race condition, which in turn leads to a use-after-free error and allows privilege escalation.
3) Permissions, Privileges, and Access Controls (CVE-ID: CVE-2022-0492)
CWE-ID: CWE-264 - Permissions, Privileges, and Access Controls
CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:A/U:Clear
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to a logic error within the cgroup_release_agent_write() function in kernel/cgroup/cgroup-v1.c. A local user can use the cgroups v1 release_agent feature to escalate privileges and bypass the namespace isolation.
4) Improper input validation (CVE-ID: CVE-2022-21426)
CWE-ID: CWE-20 - Improper input validation
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:U/U:Green
The vulnerability allows a remote non-authenticated attacker to perform service disruption.
The vulnerability exists due to improper input validation within the JAXP component in Oracle GraalVM Enterprise Edition. A remote non-authenticated attacker can exploit this vulnerability to perform service disruption.
5) Improper input validation (CVE-ID: CVE-2022-21434)
CWE-ID: CWE-20 - Improper input validation
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:L/VA:N/SC:N/SI:N/SA:N/E:U/U:Green
The vulnerability allows a remote non-authenticated attacker to manipulate data.
The vulnerability exists due to improper input validation within the Libraries component in Oracle GraalVM Enterprise Edition. A remote non-authenticated attacker can exploit this vulnerability to manipulate data.
6) Improper input validation (CVE-ID: CVE-2022-21443)
CWE-ID: CWE-20 - Improper input validation
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:U/U:Clear
The vulnerability allows a remote non-authenticated attacker to perform service disruption.
The vulnerability exists due to improper input validation within the Libraries component in Oracle GraalVM Enterprise Edition. A remote non-authenticated attacker can exploit this vulnerability to perform service disruption.
7) Improper input validation (CVE-ID: CVE-2022-21476)
CWE-ID: CWE-20 - Improper input validation
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Green
The vulnerability allows a remote non-authenticated attacker to gain access to sensitive information.
The vulnerability exists due to improper input validation within the Libraries component in Oracle GraalVM Enterprise Edition. A remote non-authenticated attacker can exploit this vulnerability to gain access to sensitive information.
8) Improper input validation (CVE-ID: CVE-2022-21496)
CWE-ID: CWE-20 - Improper input validation
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:L/VA:N/SC:N/SI:N/SA:N/E:U/U:Green
The vulnerability allows a remote non-authenticated attacker to manipulate data.
The vulnerability exists due to improper input validation within the JNDI component in Oracle GraalVM Enterprise Edition. A remote non-authenticated attacker can exploit this vulnerability to manipulate data.
9) Heap-based buffer overflow (CVE-ID: CVE-2022-25636)
CWE-ID: CWE-122 - Heap-based Buffer Overflow
CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:P/U:Clear
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to a boundary error in net/netfilter/nf_dup_netdev.c in the Linux kernel, related to nf_tables_offload. A local user can trigger a heap-based buffer overflow and execute arbitrary code with elevated privileges.
