Description
This security bulletin contains information about 15 secuirty vulnerabilities.
1) Spoofing attack (CVE-ID: CVE-2023-29533)
The vulnerability allows a remote attacker to perform spoofing attack.
The vulnerability exists due to incorrect processing of user-supplied data. A remote attacker can hide the fullscreen notification by using a combination of window.open, fullscreen requests, window.name assignments, and setInterval calls.
2) Buffer overflow (CVE-ID: CVE-2023-29535)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error during Garbage Collector compaction. A remote attacker can create a specially crafted website, 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.
3) Release of invalid pointer or reference (CVE-ID: CVE-2023-29536)
The vulnerability allows a remote attacker to execute arbitrary code on the system.
The vulnerability exists due to an invalid free operation from JavaScript code. A remote attacker can trick the victim to visit a specially crafted web page, trigger memory corruption and execute arbitrary code.
4) Race condition (CVE-ID: CVE-2023-29537)
The vulnerability allows a remote attacker to compromise the affected system.
The vulnerability exists due to multiple race conditions in font initialization code. A remote attacker can trick the victim into visiting a malicious website, trigger a race condition and execute arbitrary code
5) File and directory information exposure (CVE-ID: CVE-2023-29538)
The vulnerability allows a remote attacker to gain access to sensitive information.
The vulnerability exists due to the way WebExtension handles the "jar:file:///" URI during the request load. A remote attacker can obtain directory paths on the user's machine.
6) Security features bypass (CVE-ID: CVE-2023-29539)
The vulnerability allows a remote attacker to bypass implemented security restrictions.
The vulnerability exists due to improper handling of filename directive in the Content-Disposition header, which leads to filename truncation if it contains a NULL character. A remote attacker can abuse such behavior and trick the victim into downloading a malicious file.
7) Security features bypass (CVE-ID: CVE-2023-29540)
The vulnerability allows a remote attacker to bypass implemented security restrictions.
The vulnerability exists due to incorrect processing of iframes. A remote attacker can use a redirect embedded into sourceMappingUrls to allow navigation to external protocol links in sandboxed iframes without allow-top-navigation-to-custom-protocols.
8) Security features bypass (CVE-ID: CVE-2023-29541)
The vulnerability allows a remote attacker to bypass implemented security restrictions.
The vulnerability exists due to improper handling of filenames ending with .desktop. A remote attacker can trick the victim into downloading a malicious file and execute it on the system.The vulnerability affects Firefox on Linux only.
9) Use-after-free (CVE-ID: CVE-2023-29543)
The vulnerability allows a remote attacker to compromise vulnerable system.
The vulnerability exists due to a use-after-free error in debugging APIs. A remote attacker can trick the victim to visit a specially crafted website, trigger a use-after-free error and execute arbitrary code on the system.
Successful exploitation of the vulnerability may allow an attacker to compromise vulnerable system.
10) Buffer overflow (CVE-ID: CVE-2023-29544)
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 website, 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.
11) Spoofing attack (CVE-ID: CVE-2023-29547)
The vulnerability allows a remote attacker to perform spoofing attack.
The vulnerability exists due to insecure handling of cookies in Firefox cookie jar. When a secure cookie existed in the Firefox cookie jar an insecure cookie for the same domain could have been created, when it should have silently failed. This could have led to a desynchronization in expected results when reading from the secure cookie.
12) Processor optimization removal or modification of security-critical code (CVE-ID: CVE-2023-29548)
The vulnerability allows a remote attacker to gain access to sensitive information.
The vulnerability exists due to usage of a wrong lowering instruction in the ARM64 Ion compiler. A remote attacker can gain access to sensitive information.
13) Security features bypass (CVE-ID: CVE-2023-29549)
The vulnerability allows a remote attacker to bypass certain security restrictions.
The vulnerability exists due to an error in JavaScript bind functionality. Under certain circumstances, a call to the bind function may have resulted in the incorrect realm. This may have created a vulnerability relating to JavaScript-implemented sandboxes such as SES.
14) Buffer overflow (CVE-ID: CVE-2023-29550)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error when parsing HTML content. A remote attacker can create a specially crafted website, 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.
15) Buffer overflow (CVE-ID: CVE-2023-29551)
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 website, 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.
