Arch Linux: ASA-202110-10 Medium Severity: Wpewebkit Code Execution Risks

The package wpewebkit before version 2.34.1-1 is vulnerable to multiple issues including arbitrary code execution and sandbox escape. . Arch Linux Security Advisory ASA-202110-10 ========================================= Severity: Medium Date : 2021-10-29 CVE-ID : CVE-2021-30846 CVE-2021-30851 CVE-2021-42762 Package : wpewebkit Type : multiple issues Remote : Yes Link : https://security.archlinux.org/AVG-2484 Summary ====== The package wpewebkit before version 2.34.1-1 is vulnerable to multiple issues including arbitrary code execution and sandbox escape. Resolution ========= Upgrade to 2.34.1-1. # pacman -Syu "wpewebkit> =2.34.1-1" The problems have been fixed upstream in version 2.34.1. Workaround ========= None. Description ========== - CVE-2021-30846 (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. - CVE-2021-30851 (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. - CVE-2021-42762 (sandbox escape) 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. Impact ===== A remote attacker could execute arbitrary code or escape the confinements of the security sandbox through crafted webcontent.
