Security Bulletin
This security bulletin contains information about 2 vulnerabilities.
1) OS Command Injection
EUVDB-ID: #VU84789
Risk: Medium
CVSSv4.0: 6.6 [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:P/U:Green]
CVE-ID: CVE-2023-51385
CWE-ID:
CWE-78 - Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection')
Exploit availability: Yes
DescriptionThe vulnerability allows a remote attacker to execute arbitrary shell commands on the target system.
The vulnerability exists due to improper input validation when processing user names, if a user name or host name has shell metacharacters, and this name is referenced by an expansion token in certain situations. A remote attacker can execute arbitrary OS commands via an untrusted Git repository.
MitigationUpdate the affected package openssh to the latest version.

2) Information disclosure
EUVDB-ID: #VU93514
Risk: Low
CVSSv4.0: 4.3 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear]
CVE-ID: CVE-2024-39894
CWE-ID:
CWE-200 - Information exposure
Exploit availability: No
DescriptionThe vulnerability allows a local user to gain access to potentially sensitive information.
The vulnerability exists due a logic error in ObscureKeystrokeTiming implementation within the ssh client. A local user with ability to passively observe SSH sessions can recover sensitive input, such as password for the su or sudo programs.
Update the affected package openssh to the latest version.
