Description
This security bulletin contains information about 15 secuirty vulnerabilities.
1) Out-of-bounds write (CVE-ID: CVE-2023-29531)
The vulnerability allows a remote attacker to compromise vulnerable system.
The vulnerability exists due to a boundary error when processing untrusted input in WebGL API. A remote attacker can trick the victim to visit a specially crafted website, trigger an out-of-bounds write and execute arbitrary code on the target system.
Note, the vulnerability affects only Firefox for macOS.
2) Permissions, Privileges, and Access Controls (CVE-ID: CVE-2023-29532)
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to the way Mozilla Maintenance Service handles write-locks when downloading updates from a SMB server. A local user can apply an unsigned update file by pointing the service at an update file on a malicious SMB server.
The vulnerability affects only Firefox for Windows.
3) 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.
4) 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.
5) 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.
6) Security features bypass (CVE-ID: CVE-2023-0547)
The vulnerability allows a remote attacker to gain access to sensitive information.
The vulnerability exists due to an error when processing revocation status of S/mime recipient certificates. OCSP revocation status of recipient certificates is not checked when sending S/Mime encrypted email, as a result revoked certificates are accepted.
7) Input validation error (CVE-ID: CVE-2023-29479)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to insufficient validation of user-supplied input within the Ribose RNP library when parsing PKESK/SKESK packets. A remote attacker can send specially crafted OpenPGP messages to the application and perform a denial of service (DoS) attack.
8) 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.
9) 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.
10) Security features bypass (CVE-ID: CVE-2023-29542)
The vulnerability allows a remote attacker to bypass implemented security restrictions.
The vulnerability exists due to improper handling of newline in a filename. A remote attacker can bypass the file extension security mechanisms that replaces dangerous file extensions such as .lnk with .download and potentially compromise the affected system.11) Information disclosure (CVE-ID: CVE-2023-29545)
The vulnerability allows a remote attacker to gain access to potentially sensitive information.
The vulnerability exists due to excessive data output by the application when downloading files through the "Save Link As" on Windows with suggested filenames containing environment variable names. A remote attacker can gain unauthorized access to sensitive information on the system.
Note, the vulnerability affects only Windows installations.12) Buffer overflow (CVE-ID: CVE-2023-1945)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error in the Safe Browsing API. 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.
13) 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.
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) Double Free (CVE-ID: CVE-2023-1999)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error in libwebp. A remote attacker can trick the victim to visit a specially crafted page, trigger a double free error and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
