Description
This security bulletin contains information about 7 vulnerabilities.
1) Out-of-bounds write (CVE-ID: CVE-2023-6204)
CWE-ID: CWE-787 - Out-of-bounds write
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Amber
The vulnerability allows a remote attacker to compromise vulnerable system.
The vulnerability exists due to a boundary error when processing HTML content in in WebGL2 blitFramebuffer. A remote attacker can trick the victim ti visit a specially crafted website, trigger an out-of-bounds write and execute arbitrary code on the target system.
2) Use-after-free (CVE-ID: CVE-2023-6205)
CWE-ID: CWE-416 - Use After Free
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Amber
The vulnerability allows a remote attacker to compromise vulnerable system.
The vulnerability exists due to a use-after-free error in the MessagePort::Entangled() method. A remote attacker can trick the victim to open 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.
3) Multiple Interpretations of UI Input (CVE-ID: CVE-2023-6206)
CWE-ID: CWE-450 - Multiple Interpretations of UI Input
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N/E:U/U:Green
The vulnerability allows a remote attacker to perform clickjacking attack.
The vulnerability exists due to the black fade animation when exiting fullscreen is roughly
the length of the anti-clickjacking delay on permission prompts. A remote attacker can perform clickjacking attack and trick the victim into pressing the permissions grant button.
4) Use-after-free (CVE-ID: CVE-2023-6207)
CWE-ID: CWE-416 - Use After Free
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Amber
The vulnerability allows a remote attacker to compromise vulnerable system.
The vulnerability exists due to a use-after-free error in the ReadableByteStreamQueueEntry::Buffer() method. A remote attacker can trick the victim to open 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.
5) Information disclosure (CVE-ID: CVE-2023-6208)
CWE-ID: CWE-200 - Exposure of sensitive information to an unauthorized actor
CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear
The vulnerability allows a local user to gain access to potentially sensitive information.
The vulnerability exists due to the Selection API copies text by mistake into the primary selection, a temporary storage not unlike the clipboard, when using on X11. A local user can gain access to potentially sensitive information.
Note, the vulnerability affects only Firefox installations on X11.
6) Input validation error (CVE-ID: CVE-2023-6209)
CWE-ID: CWE-20 - Improper input validation
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N/E:U/U:Green
The vulnerability allows a remote attacker to manipulate data on websites.
The vulnerability exists due to insufficient validation of user-supplied input when parsing relative URLs that start with a triple slash, e.g. "///". A remote attacker can use a path-traversal "/../" part in the path to override the specified host.
7) Memory corruption (CVE-ID: CVE-2023-6212)
CWE-ID: CWE-119 - Memory corruption
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Amber
The vulnerability allows a remote attacker to compromise vulnerable system.
The vulnerability exists due to a boundary error when processing HTML content. A remote attacker can trick the victim ti visit a specially crafted website, trigger a memory corruption and execute arbitrary code on the target system.
