Description

This security bulletin contains information about 7 secuirty vulnerabilities.


1) Buffer overflow (CVE-ID: CVE-2022-26700)

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 in WebKit. A remote attacker can trick the victim to visit a specially crafted website, trigger memory corruption and execute arbitrary code on the target system.

Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.


2) Use-after-free (CVE-ID: CVE-2022-26709)

The vulnerability allows a remote attacker to compromise vulnerable system.

The vulnerability exists due to a use-after-free error when processing HTML content in WebKit. A remote attacker can trick the victim to visit a specially crafted website, trigger memory corruption and execute arbitrary code on the system.

Successful exploitation of the vulnerability may allow an attacker to compromise vulnerable system.


3) Use-after-free (CVE-ID: CVE-2022-26717)

The vulnerability allows a remote attacker to compromise vulnerable system.

The vulnerability exists due to a use-after-free error when processing HTML content in WebKit. A remote attacker can trick the victim to visit a specially crafted website, trigger memory corruption and execute arbitrary code on the system.

Successful exploitation of the vulnerability may allow an attacker to compromise vulnerable system.


4) Buffer overflow (CVE-ID: CVE-2022-26716)

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 in WebKit. A remote attacker can trick the victim to visit a specially crafted website, 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) Buffer overflow (CVE-ID: CVE-2022-26719)

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 in WebKit. A remote attacker can trick the victim to visit a specially crafted website, trigger memory corruption and execute arbitrary code on the target system.

Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.


6) Use-after-free (CVE-ID: CVE-2022-30294)

The vulnerability allows a remote attacker to compromise vulnerable system.

The vulnerability exists due to a use-after-free error when processing HTML content within the WebCore::TextureMapperLayer::setContentsLayer() function in WebCore/platform/graphics/texmap/TextureMapperLayer.cpp. 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.


7) Heap-based buffer overflow (CVE-ID: CVE-2022-30293)

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to a boundary error within the WebCore::TextureMapperLayer::setContentsLayer() function in WebCore/platform/graphics/texmap/TextureMapperLayer.cpp. A remote attacker can trick the victim into visiting a specially crafted web page, trigger a heap-based buffer overflow and execute arbitrary code on the target system.

Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
