Description

This security bulletin contains information about 3 secuirty vulnerabilities.


1) Information Exposure Through Timing Discrepancy (CVE-ID: CVE-2023-5981)

The vulnerability allows a remote attacker to perform timing attack.

The vulnerability exists due to the response times to malformed ciphertexts in RSA-PSK ClientKeyExchange differ from response times of ciphertexts with correct PKCS#1 v1.5 padding. A remote attacker can perform timing sidechannel attack in RSA-PSK key exchange.


2) Out-of-bounds write (CVE-ID: CVE-2024-0533)

The vulnerability allows a remote privileged user to compromise vulnerable system.

The vulnerability exists in the file /goform/SetOnlineDevName of the component Web-based Management Interface. A remote privileged user can send a specially crafted file, trigger an out-of-bounds write and execute arbitrary code on the target system.


3) Information Exposure Through Timing Discrepancy (CVE-ID: CVE-2024-0553)

The vulnerability allows a remote attacker to perform timing attack.

The vulnerability exists due to the response times to malformed ciphertexts in RSA-PSK ClientKeyExchange differ from response times of ciphertexts with correct PKCS#1 v1.5 padding. A remote attacker can perform timing sidechannel attack in RSA-PSK key exchange.

Note, the vulnerability exists due to incomplete fox for #VU83316 (CVE-2023-5981).
