"The remote NewStart CGSL host, running version MAIN 6.02, has libwebp packages installed that are affected by multiple
vulnerabilities:

  - A heap-based buffer overflow was found in libwebp in versions before 1.0.1 in GetLE16(). (CVE-2018-25009)

  - A heap-based buffer overflow was found in libwebp in versions before 1.0.1 in ApplyFilter().
    (CVE-2018-25010)

  - A heap-based buffer overflow was found in libwebp in versions before 1.0.1 in GetLE24(). (CVE-2018-25012)

  - A heap-based buffer overflow was found in libwebp in versions before 1.0.1 in ShiftBytes().
    (CVE-2018-25013)

  - A use of uninitialized value was found in libwebp in versions before 1.0.1 in ReadSymbol().
    (CVE-2018-25014)

  - A flaw was found in libwebp in versions before 1.0.1. An out-of-bounds read was found in function
    ChunkVerifyAndAssign. The highest threat from this vulnerability is to data confidentiality and to the
    service availability. (CVE-2020-36330)

  - A flaw was found in libwebp in versions before 1.0.1. An out-of-bounds read was found in function
    ChunkAssignData. The highest threat from this vulnerability is to data confidentiality and to the service
    availability. (CVE-2020-36331)

  - A flaw was found in libwebp in versions before 1.0.1. When reading a file libwebp allocates an excessive
    amount of memory. The highest threat from this vulnerability is to the service availability.
    (CVE-2020-36332)

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