"The remote SUSE Linux SLED15 / SLED_SAP15 / SLES15 / SLES_SAP15 / openSUSE 15 host has packages installed that are
affected by multiple vulnerabilities as referenced in the SUSE-SU-2023:4472-1 advisory.

  - Line directives (//line) can be used to bypass the restrictions on //go:cgo_ directives, allowing
    blocked linker and compiler flags to be passed during compilation. This can result in unexpected execution
    of arbitrary code when running go build. The line directive requires the absolute path of the file in
    which the directive lives, which makes exploiting this issue significantly more complex. (CVE-2023-39323)

  - A malicious HTTP/2 client which rapidly creates requests and immediately resets them can cause excessive
    server resource consumption. While the total number of requests is bounded by the
    http2.Server.MaxConcurrentStreams setting, resetting an in-progress request allows the attacker to create
    a new request while the existing one is still executing. With the fix applied, HTTP/2 servers now bound
    the number of simultaneously executing handler goroutines to the stream concurrency limit
    (MaxConcurrentStreams). New requests arriving when at the limit (which can only happen after the client
    has reset an existing, in-flight request) will be queued until a handler exits. If the request queue grows
    too large, the server will terminate the connection. This issue is also fixed in golang.org/x/net/http2
    for users manually configuring HTTP/2. The default stream concurrency limit is 250 streams (requests) per
    HTTP/2 connection. This value may be adjusted using the golang.org/x/net/http2 package; see the
    Server.MaxConcurrentStreams setting and the ConfigureServer function. (CVE-2023-39325)

  - The HTTP/2 protocol allows a denial of service (server resource consumption) because request cancellation
    can reset many streams quickly, as exploited in the wild in August through October 2023. (CVE-2023-44487)

  - The filepath package does not recognize paths with a \??\ prefix as special. On Windows, a path beginning
    with \??\ is a Root Local Device path equivalent to a path beginning with \\?\. Paths with a \??\ prefix
    may be used to access arbitrary locations on the system. For example, the path \??\c:\x is equivalent to
    the more common path c:\x. Before fix, Clean could convert a rooted path such as \a\..\??\b into the root
    local device path \??\b. Clean will now convert this to .\??\b. Similarly, Join(\, ??, b) could convert a
    seemingly innocent sequence of path elements into the root local device path \??\b. Join will now convert
    this to \.\??\b. In addition, with fix, IsAbs now correctly reports paths beginning with \??\ as absolute,
    and VolumeName correctly reports the \??\ prefix as a volume name. (CVE-2023-45283)

  - On Windows, The IsLocal function does not correctly detect reserved device names in some cases. Reserved
    names followed by spaces, such as COM1 , and reserved names COM and LPT followed by superscript 1,
    2, or 3, are incorrectly reported as local. With fix, IsLocal now correctly reports these names as non-
    local. (CVE-2023-45284)

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