Description
This security bulletin contains information about 5 vulnerabilities.
1) Security restrictions bypass (CVE-ID: CVE-2022-23648)
CWE-ID: CWE-264 - Permissions, Privileges, and Access Controls
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N/E:P/U:Green
The vulnerability allows a remote attacker to gain access to sensitive information.
The vulnerability exists due to an error when handling specially crafted image configuration in containerd where containers launched through containerd’s CRI implementation. A remote attacker can bypass any policy-based enforcement on container setup and access the read-only copies of arbitrary files and directories on the host.
2) Improper Verification of Cryptographic Signature (CVE-ID: CVE-2022-34903)
CWE-ID: CWE-347 - Improper Verification of Cryptographic Signature
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:N/VI:H/VA:N/SC:N/SI:N/SA:N/E:U/U:Green
The vulnerability allows a remote attacker to perform spoofing attack.
The vulnerability exists due to an error in GnuPG, which allows signature spoofing via arbitrary injection into the status line. A remote attacker who controls the secret part of any signing-capable key or subkey in the victim's keyring, can take advantage of this flaw to provide a correctly-formed signature that some software, including gpgme, will accept to have validity and signer fingerprint chosen from the attacker.
3) Permissions, Privileges, and Access Controls (CVE-ID: CVE-2019-16884)
CWE-ID: CWE-264 - Permissions, Privileges, and Access Controls
CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:L/VI:H/VA:N/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 incorrect checking of the mount targets in libcontainer/rootfs_linux.go in runc. A local user can bypass AppArmor restrictions and perform unauthorized actions on the system, as demonstrated by overwriting the /proc directory with a malicious Doker image.
4) Authentication Bypass by Spoofing (CVE-ID: CVE-2022-22476)
CWE-ID: CWE-290 - Authentication Bypass by Spoofing
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Green
The vulnerability allows a remote attacker to execute identity spoofing attacks.
The vulnerability exists due to an unspecified error in IBM WebSphere Application Server Liberty. A remote authenticated user can send a specially crafted request to perform identity spoofing attacks.
5) Security features bypass (CVE-ID: CVE-2021-30465)
CWE-ID: CWE-254 - Security Features
CVSSv4: CVSS:4.0/AV:A/AC:L/AT:N/PR:L/UI:N/VC:H/VI:L/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear
The vulnerability allows a remote attacker to compromise the target system.
The vulnerability exists due to the security features bypass issue. A remote authenticated attacker on the local network can perform a symlink exchange attack and host filesystem being bind-mounted into the container.
