Description

Arch Linux Security Advisory ASA-202007-1 ========================================= Severity: Critical Date : 2020-07-14 CVE-ID : CVE-2020-9802 CVE-2020-9803 CVE-2020-9805 CVE-2020-9806 CVE-2020-9807 CVE-2020-9843 CVE-2020-9850 CVE-2020-13753 Package : webkit2gtk Type : multiple issues Remote : Yes Link : https://security.archlinux.org/AVG-1203 Summary ======= The package webkit2gtk before version 2.28.3-1 is vulnerable to multiple issues including arbitrary code execution, cross-site scripting and sandbox escape. Resolution ========== Upgrade to 2.28.3-1. # pacman -Syu "webkit2gtk>=2.28.3-1" The problems have been fixed upstream in version 2.28.3. Workaround ========== None. Description =========== - CVE-2020-9802 (arbitrary code execution) A memory corruption issue has been found in WebKitGTK before 2.28.3 and WPE WebKit before 2.2.8.3, where processing maliciously crafted web content may lead to arbitrary code execution. - CVE-2020-9803 (arbitrary code execution) A memory corruption issue has been found in WebKitGTK before 2.28.3 and WPE WebKit before 2.2.8.3, where processing maliciously crafted web content may lead to arbitrary code execution. - CVE-2020-9805 (cross-site scripting) A logic issue has been found in WebKitGTK before 2.28.3 and WPE WebKit before 2.2.8.3, where processing maliciously crafted web content may lead to universal cross site scripting. - CVE-2020-9806 (arbitrary code execution) A memory corruption issue has been found in WebKitGTK before 2.28.3 and WPE WebKit before 2.2.8.3, where processing maliciously crafted web content may lead to arbitrary code execution. - CVE-2020-9807 (arbitrary code execution) A memory corruption issue has been found in WebKitGTK before 2.28.3 and WPE WebKit before 2.2.8.3, where processing maliciously crafted web content may lead to arbitrary code execution. - CVE-2020-9843 (cross-site scripting) An issue has been found in WebKitGTK before 2.28.3 and WPE WebKit before 2.2.8.3, where processing maliciously crafted web content may lead to a cross site scripting attack. - CVE-2020-9850 (arbitrary code execution) A logic issue has been found in WebKitGTK before 2.28.3 and WPE WebKit before 2.2.8.3, allowing a remote attacker to execute arbitrary code. - CVE-2020-13753 (sandbox escape) The bubblewrap sandbox of WebKitGTK and WPE WebKit, prior to 2.28.3, failed to properly block access to CLONE_NEWUSER and the TIOCSTI ioctl. CLONE_NEWUSER could potentially be used to confuse xdg- desktop-portal, which allows access outside the sandbox. TIOCSTI can be used to directly execute commands outside the sandbox by writing to the controlling terminal’s input buffer, similar to CVE-2017-5226. Impact ====== A remote attacker might be able to trigger cross-site scripting, bypass the sandbox and execute arbitrary code on the affected host.
