Description

This security bulletin contains information about 9 secuirty vulnerabilities.


1) Permissions, Privileges, and Access Controls (CVE-ID: CVE-2022-24769)

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)

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)

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)

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)

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)

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)

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)

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)

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.
