Description

This security bulletin contains information about 6 vulnerabilities.


1) Race condition (CVE-ID: CVE-2021-36221)

CWE-ID: CWE-362 - Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition')

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green


The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to a race condition in net/http/httputil ReverseProxy when handling ErrAbortHandler events. A remote attacker can trigger a race condition and crash the ReverseProxy.


2) Type Confusion (CVE-ID: CVE-2021-41190)

CWE-ID: CWE-843 - Type confusion

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:P/PR:L/UI:A/VC:N/VI:L/VA:N/SC:N/SI:L/SA:N/E:U/U:Clear


The vulnerability allows a remote attacker to compromise the system.

The vulnerability exists due to a type confusion error. A remote authenticated attacker can pass specially crafted data to the application, trigger a type confusion error and interpret the resulting content differently.


3) Resource exhaustion (CVE-ID: CVE-2022-1708)

CWE-ID: CWE-400 - Resource exhaustion

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green


The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to application does not properly control consumption of internal resources within the ExecSync request. A remote attacker can trigger resource exhaustion and perform a denial of service (DoS) attack.


4) Incorrect authorization (CVE-ID: CVE-2022-2990)

CWE-ID: CWE-863 - Incorrect Authorization

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:U/U:Clear


The vulnerability allows a local user to escalate privileges on the system.

The vulnerability exists due to incorrect handling of the supplementary groups in the Buildah container engine. A local user with direct access to the affected container where supplementary groups are used can set access permissions and execute a binary code in that container.

5) Use of a broken or risky cryptographic algorithm (CVE-ID: CVE-2022-27191)

CWE-ID: CWE-327 - Use of a Broken or Risky Cryptographic Algorithm

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green


The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to an error in golang.org/x/crypto/ssh before 0.0.0-20220314234659-1baeb1ce4c0b, as used in Go programming language. A remote attacker can crash a server in certain circumstances involving AddHostKey.


6) Permissions, Privileges, and Access Controls (CVE-ID: CVE-2022-29162)

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.
