Debian DSA-5154-1 : webkit2gtk - security update

critical Nessus Plugin ID 161747

Synopsis

The remote Debian host is missing one or more security-related updates.

Description

The remote Debian 10 / 11 host has packages installed that are affected by multiple vulnerabilities as referenced in the dsa-5154 advisory.

- In WebKitGTK through 2.36.0 (and WPE WebKit), there is a heap-based buffer overflow in WebCore::TextureMapperLayer::setContentsLayer in WebCore/platform/graphics/texmap/TextureMapperLayer.cpp.
(CVE-2022-30293)

- In WebKitGTK through 2.36.0 (and WPE WebKit), there is a use-after-free in WebCore::TextureMapperLayer::setContentsLayer in WebCore/platform/graphics/texmap/TextureMapperLayer.cpp.
(CVE-2022-30294)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Upgrade the webkit2gtk packages.

For the stable distribution (bullseye), these problems have been fixed in version 2.36.3-1~deb11u1.
