SB2024071519 - SUSE update for cockpit

Description

This security bulletin contains information about 6 secuirty vulnerabilities.

1) Resource exhaustion (CVE-ID: CVE-2024-6126)

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. A remote user can trigger resource exhaustion and perform a denial of service (DoS) attack.

2) Improper input validation (CVE-ID: N/A)

The vulnerability allows a remote attacker to bypass certain security restrictions.

The vulnerability exists due to an error in sshd, which can be used to bypass address-based access controls if the AllowUser directive is configured with invalid CIDR address ranges.

Successful exploitation of this vulnerability may allow a remote attacker to bypass implemented access control mechanisms and perform a further attacks against vulnerable system.

3) Buffer overflow (CVE-ID: CVE-2016-10012)

The vulnerability allows a local user to execute arbitrary code on vulnerable system with root privileges.

The vulnerability exists in sshd due to a flaw in boundary checks in the shared memory manager that may be skipped by some optimizing compilers. A local user can trigger memory corruption and execute arbitrary code with root privileges. The issue is related to m_zback and m_zlib data structures.

Successful exploitation of this vulnerability may allow a local user to elevate privileges.

4) Information disclosure (CVE-ID: CVE-2016-10011)

The vulnerability allows a local user to gain access to potentially sensitive information.

The vulnerability exists due to an error in authfile.c, which may allow a local authenticated user to obtain host private key material.

Successful exploitation of this vulnerability may allow a local user to gain access to otherwise restricted information.

5) Privilege escalation (CVE-ID: CVE-2016-10010)

The vulnerability allows a local user to execute arbitrary code on vulnerable system with root privileges.

The vulnerability exists due to an error in sshd in serverloop.c, which may allow a local authenticated user to execute arbitrary code with root privileges via a forwarded Unix-domain socket.

Successful exploitation of this vulnerability may allow a local user to elevate privileges.

6) Improper input validation (CVE-ID: CVE-2016-10009)

The vulnerability allows a remote attacker to execute arbitrary code on vulnerable ssh client.

The vulnerability exists due to incorrect handling of data passed to PKCS#11 module within ssh-agent. A remote attacker with control over sshd service can execute arbitrary code on vulnerable client.

Successful exploitation of this vulnerability may allow a remote attacker to execute arbitrary code on vulnerable client system but requires that client is connected to malicious SSH server.
