Description

This security bulletin contains information about 7 vulnerabilities.


1) OS Command Injection (CVE-ID: CVE-2023-6004)

CWE-ID: CWE-78 - Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection')

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


The vulnerability allows a remote attacker to execute arbitrary shell commands on the target system.

The vulnerability exists due to improper input validation in OpenSSH client. If an invalid user or hostname that contained shell metacharacters was passed to ssh(1), and a ProxyCommand, LocalCommand directive or "match exec" predicate referenced the user or hostname via %u, %h or similar expansion token, then an attacker who could supply arbitrary user/hostnames to ssh(1) could potentially perform command injection depending on what quoting was present in the user-supplied ssh_config(5) directive.



2) Unchecked Return Value (CVE-ID: CVE-2023-6918)

CWE-ID: CWE-252 - Unchecked Return Value

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


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

The vulnerability exists due to libssh does not check for returned values of message digest (MD) operations in low memory conditions. A remote attacker can terminate the connection or force the library to use weak keys.


3) Resource exhaustion (CVE-ID: CVE-2024-22365)

CWE-ID: CWE-400 - Resource exhaustion

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


The vulnerability allows a local user to perform a denial of service (DoS) attack.

The vulnerability exists due to application does not properly control consumption of internal resources in pam_namespace. A local user can trigger resource exhaustion and perform a denial of service (DoS) attack.


4) Memory leak (CVE-ID: CVE-2024-26458)

CWE-ID: CWE-401 - Missing release of memory after effective lifetime

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 memory leak in /krb5/src/lib/rpc/pmap_rmt.c. A remote attacker can perform a denial of service attack.


5) Insufficient verification of data authenticity (CVE-ID: CVE-2023-7008)

CWE-ID: CWE-345 - Insufficient Verification of Data Authenticity

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


The vulnerability allows a remote attacker to perform a MitM attack.

The vulnerability exists due to systemd-resolved accepts records of DNSSEC-signed domains even when they have no signature. A remote attacker can perform MitM attack.


6) Resource exhaustion (CVE-ID: CVE-2024-3651)

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 idna.encode() function. A remote attacker can pass an overly long domain name to the application and perform a denial of service (DoS) attack.


7) Use of a broken or risky cryptographic algorithm (CVE-ID: CVE-2024-27256)

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

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


The vulnerability allows a remote attacker to gain access to sensitive information.

The vulnerability exists due to usage of weak encryption algorithms. A remote attacker can decrypt sensitive information.
