The remote SUSE Linux SLES15 / SLES_SAP15 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2021:3769-1 advisory.

  - 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 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)

  - 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)

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