CVEID: CVE-2021-23981
DESCRIPTION: Mozilla Firefox is vulnerable to a denial of service, caused by an out-of-bound read when a texture upload of a Pixel Buffer Object confuses the WebGL code to skip binding the buffer used to unpack it. By persuading a victim to visit a specially-crafted Web site, a remote attacker could exploit this vulnerability to corrupt memory and cause the browser to crash.
CVSS Base score: 6.5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/198594 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H)
CVEID: CVE-2021-23984
DESCRIPTION: Mozilla Firefox could allow a remote attacker to conduct spoofing attacks, caused by a malicious extension opening a popup window. By persuading a victim to visit a specially-crafted Web site, a remote attacker could exploit this vulnerability to spoof the Web site and attempt to trick the user into providing credentials.
CVSS Base score: 6.5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/198597 for the current score.
