Description
This security bulletin contains information about 10 secuirty vulnerabilities.
1) Information disclosure (CVE-ID: CVE-2022-2403)
The vulnerability allows a remote attacker to gain access to potentially sensitive information.
The vulnerability exists due to the private key for the external cluster certificate is stored incorrectly in the oauth-serving-cert ConfigMaps and accessible to any authenticated OpenShift user or service-account. A remote user can read the oauth-serving-cert ConfigMap in the openshift-config-managed namespace and compromise any web traffic secured using that certificate.
2) Out-of-bounds write (CVE-ID: CVE-2020-29368)
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to a boundary error when processing untrusted input within the __split_huge_pmd() function in mm/huge_memory.c in the Linux kernel. A local user can abuse the copy-on-write implementation and gain unintended write access because of a race condition in a THP mapcount check.
3) Security restrictions bypass (CVE-ID: CVE-2021-4197)
The 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.
4) Use-after-free (CVE-ID: CVE-2021-4203)
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to a use-after-free error in sock_getsockopt() function in net/core/sock.c due to SO_PEERCRED and SO_PEERGROUPS race with listen() function (and connect() function) in the Linux kernel. A local user can exploit the use-after-free error and crash the system or escalate privileges on the system.
5) Memory leak (CVE-ID: CVE-2022-1012)
The vulnerability allows a remote attacker to gain access to sensitive information.
The vulnerability exists due to insufficient randomization in the net/ipv4/tcp.c when calculating port offsets in Linux kernel cause by small table perturb size. A remote attacker can cause memory leak and gain access to sensitive information.
6) Race condition (CVE-ID: CVE-2022-1729)
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to a race condition within sys_perf_event_open() in Linux kernel. A local user can exploit the race and gain unauthorized access to sensitive information and escalate privileges on the system.
7) Improper input validation (CVE-ID: CVE-2022-21540)
The vulnerability allows a remote non-authenticated attacker to gain access to sensitive information.
The vulnerability exists due to improper input validation within the Hotspot 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-2022-21541)
The vulnerability allows a remote non-authenticated attacker to manipulate data.
The vulnerability exists due to improper input validation within the Hotspot component in Oracle GraalVM Enterprise Edition. A remote non-authenticated attacker can exploit this vulnerability to manipulate data.
9) Use-after-free (CVE-ID: CVE-2022-32250)
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to a use-after-free incorrect NFT_STATEFUL_EXPR in net/netfilter/nf_tables_api.c in Linux kernel. A local user with ability to create user/net namespaces can execute arbitrary code with root privileges.
10) Improper input validation (CVE-ID: CVE-2022-34169)
The vulnerability allows a remote non-authenticated attacker to compromise the affected system.
The vulnerability exists due to an integer truncation issue when processing malicious XSLT stylesheets. A remote non-authenticated attacker can pass specially crafted data to the application to corrupt Java class files generated by the internal XSLTC compiler and execute arbitrary Java bytecode.
