Vulnerability Details

CVEID:CVE-2020-26974
**DESCRIPTION:**Mozilla Firefox could allow a remote attacker to execute arbitrary code on the system, caused by a heap use-after-free when a StyleGenericFlexBasis object is incorrectly cast to the wrong type. By persuading a victim to visit a specially-crafted Web site, a remote attacker could exploit this vulnerability using unknown attack vectors to execute arbitrary code on the vulnerable system or cause a denial of service.
CVSS Base score: 8.8
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/193222 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H)

CVEID:CVE-2020-35111
**DESCRIPTION:**Mozilla Firefox could allow a remote attacker to obtain sensitive information, caused by the failure to catch view-source URLs by the proxy.onRequest API. By persuading a victim to open View Source, a remote attacker could exploit this vulnerability to disclose their IP address.
CVSS Base score: 6.5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/193228 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:N/A:N)

CVEID:CVE-2020-26973
**DESCRIPTION:**Mozilla Firefox could allow a remote attacker to bypass security restrictions, caused by the performance of incorrect sanitation by the CSS Sanitizer. By persuading a victim to visit a specially-crafted Web site, a remote attacker could exploit this vulnerability to remove incorrect components.
CVSS Base score: 6.5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/193221 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:H/A:N)

CVEID:CVE-2020-26978
**DESCRIPTION:**Mozilla Firefox could allow a remote attacker to obtain sensitive information, caused by the use of techniques built on the slipstream research. By persuading a victim to visit a specially-crafted Web site, a remote attacker could exploit this vulnerability to expose internal network’s hosts as well as services running on the user’s local machine.
CVSS Base score: 6.5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/193226 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:N/A:N)

CVEID:CVE-2020-26971
**DESCRIPTION:**Mozilla Firefox is vulnerable to a heap-based buffer overflow, caused by improper bounds checking by WebGL. By persuading a victim to visit a specially-crafted Web site, a remote attacker could overflow a buffer and execute arbitrary code on the system or cause the browser to crash.
CVSS Base score: 8.8
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/193220 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H)

CVEID:CVE-2020-35112
**DESCRIPTION:**Mozilla Firefox could allow a remote attacker to execute arbitrary code on the system, caused by an error when opening an extension-less download. By persuading a victim to visit a specially-crafted Web site, a remote attacker could exploit this vulnerability to launch an executable and execute arbitrary code on the vulnerable system or cause a denial of service.
CVSS Base score: 8.8
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/193229 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H)

CVEID:CVE-2020-35113
**DESCRIPTION:**Mozilla Firefox could allow a remote attacker to execute arbitrary code on the system, caused by memory safety bugs within the browser engine. By persuading a victim to visit a specially-crafted Web site, a remote attacker could exploit this vulnerability using unknown attack vectors to execute arbitrary code on the vulnerable system or cause a denial of service.
CVSS Base score: 8.8
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/193230 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H)
