Description
This security bulletin contains information about 9 secuirty vulnerabilities.
1) Covert timing channel (CVE-ID: CVE-2023-5388)
The vulnerability allows a remote attacker to perform MitM attack.
The vulnerability exists due to insufficient fix for #VU84108 (CVE-2023-4421). A remote attacker can perform Marvin attack and gain access to sensitive information.
2) Unchecked Return Value (CVE-ID: CVE-2024-0743)
The vulnerability allows a remote attacker to compromise the affected system.
The vulnerability exists due to an unchecked return value in TLS handshake code in NSS TLS method. A remote attacker can trick the victim to visit a specially crafted website and execute arbitrary code on the system.
3) Information disclosure (CVE-ID: CVE-2024-1936)
The vulnerability allows a remote attacker to gain access to potentially sensitive information.
The vulnerability exists due to an error in Thunderbird when handling local cache. The encrypted subject of an email message could be incorrectly and permanently assigned to an arbitrary other email message in Thunderbird's local cache. Consequently, when replying to the contaminated email message, the user might accidentally leak the confidential subject to a third party.
4) Buffer overflow (CVE-ID: CVE-2024-2607)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to the JIT code fails to save return registers on Armv7-A systems. A remote attacker can execute arbitrary code on the system.
5) Integer overflow (CVE-ID: CVE-2024-2608)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to integer overflow within the AppendEncodedAttributeValue(), ExtraSpaceNeededForAttrEncoding() and AppendEncodedCharacters() function. A remote attacker can trick the victim to visit a specially crafted website, trigger an integer overflow and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
6) Security features bypass (CVE-ID: CVE-2024-2610)
The vulnerability allows a remote attacker to gain access to sensitive information.
The vulnerability exists due to an error when handling HTML code. A remote attacker with ability to inject HTML code into the page (e.g. using an XSS vulnerability) can obtain CSP nonce and bypass strict content security policies.
7) Multiple Interpretations of UI Input (CVE-ID: CVE-2024-2611)
The vulnerability allows a remote attacker to perform clickjacking attack.
The vulnerability exists due to a missing delay on the pointer lock. A remote attacker can trick the victim to visit a specially crafted website and perform a clickjacking attack.
8) Use-after-free (CVE-ID: CVE-2024-2612)
The vulnerability allows a remote attacker to compromise vulnerable system.
The vulnerability exists due to a use-after-free error when processing HTML content. A remote attacker can trick the victim to visit a specially crafted website to trigger a particular code path in SafeRefPtr and execute arbitrary code on the system.
Successful exploitation of the vulnerability may allow an attacker to compromise vulnerable system.
9) Buffer overflow (CVE-ID: CVE-2024-2614)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error when processing HTML content. A remote attacker can create a specially crafted webpage, trick the victim into opening it, trigger memory corruption and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
