CVE-ID : CVE-2021-30846 CVE-2021-30851 CVE-2021-42762
Package : webkit2gtk
Type : multiple issues
Remote : Yes
Link : https://security.archlinux.org/AVG-2483
The package webkit2gtk before version 2.34.1-1 is vulnerable to
multiple issues including arbitrary code execution and sandbox escape.
Upgrade to 2.34.1-1.
The problems have been fixed upstream in version 2.34.1.
None.
A security issue has been found in WebKitGTK and WPE WebKit before
2.34.0. Processing maliciously crafted web content may lead to
arbitrary code execution.
A security issue has been found in WebKitGTK and WPE WebKit before
2.34.0. Processing maliciously crafted web content may lead to
arbitrary code execution.
BubblewrapLauncher.cpp in WebKitGTK and WPE WebKit before 2.34.1 allows
a limited sandbox bypass that allows a sandboxed process to trick host
processes into thinking the sandboxed process is not confined by the
sandbox, by abusing VFS syscalls that manipulate its filesystem
namespace. The impact is limited to host services that create UNIX
sockets that WebKit mounts inside its sandbox, and the sandboxed
process remains otherwise confined. NOTE: this is similar to
CVE-2021-41133.
A remote attacker could execute arbitrary code or escape the
confinements of the security sandbox through crafted web content.
