CWE-ID:
CWE-416 - Use After Free
Exploit availability: No
DescriptionThe 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.

CWE-ID:
CWE-122 - Heap-based Buffer Overflow
Exploit availability: No
DescriptionThe 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.
