It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2022-2022-015 advisory.

    A use-after-free flaw was found in WebKitGTK. Specially crafted web content could use this flaw to trigger     an arbitrary code execution when processed. (CVE-2021-30809)

    A confusion type flaw was found in WebKitGTK. Specially crafted web content could use this flaw to trigger     an arbitrary code execution when processed. (CVE-2021-30818)

    A logic issue was found in WebKitGTK. An attacker in a privileged network position could use this flaw to     bypass HSTS. (CVE-2021-30823)

    An out-of-bounds read flaw was found in WebKitGTK. A specially crafted audio file could use this flaw to     trigger a disclosure of memory when processed. (CVE-2021-30836)

    A memory corruption issue was addressed with improved memory handling. This issue is fixed in iOS 14.8 and     iPadOS 14.8, Safari 15, tvOS 15, iOS 15 and iPadOS 15, watchOS 8. Processing maliciously crafted web     content may lead to arbitrary code execution. (CVE-2021-30846)

    A memory corruption issue was addressed with improved memory handling. This issue is fixed in iOS 14.8 and     iPadOS 14.8, Safari 15, iOS 15 and iPadOS 15. Processing maliciously crafted web content may lead to code     execution. (CVE-2021-30848)

    Multiple memory corruption issues were addressed with improved memory handling. This issue is fixed in iOS     14.8 and iPadOS 14.8, watchOS 8, Safari 15, tvOS 15, iOS 15 and iPadOS 15, iTunes 12.12 for Windows.
    Processing maliciously crafted web content may lead to arbitrary code execution. (CVE-2021-30849)

    A memory corruption vulnerability was addressed with improved locking. This issue is fixed in Safari 15,     tvOS 15, watchOS 8, iOS 15 and iPadOS 15. Processing maliciously crafted web content may lead to code     execution. (CVE-2021-30851)

    A flaw was found in webkitgtk. This flaw could allow an attacker to use maliciously crafted web content     leading to arbitrary code execution. (CVE-2021-30858)

    A flaw was found in the way WebKitGTK performed CSS compositing. A malicious web site could possibly use     this flaw to reveal user's browsing history. (CVE-2021-30884)

    An information leak flaw was found in WebKitGTK. A malicious web site using Content Security Policy     reports could use this flaw to leak information via redirects. (CVE-2021-30888)

    A buffer overflow flaw was found in WebKitGTK. Specially crafted web content could use this flaw to     trigger an arbitrary code execution when processed. (CVE-2021-30889)

    A flaw was found in the resource timing API specification and its implementation in WebKitGTK. A malicious     web site could use this flaw to trigger a cross-domain data exfiltration. (CVE-2021-30897)

    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. (CVE-2021-42762)

    A segmentation violation vulnerability was found in webkitgtk. An attacker with network access could pass     specially crafted HTML files causing an application to halt or crash. (CVE-2021-45481)

    A use-after-free vulnerability was found in webkitgtk. An attacker with network access could pass     specially crafted HTML files causing an application to halt or crash. (CVE-2021-45482)
