The remote NewStart CGSL host, running version CORE 5.05 / MAIN 5.05, has libwebp packages installed that are affected by multiple vulnerabilities:
A flaw was found in libwebp in versions before 1.0.1. A heap-based buffer overflow was found in PutLE16().
The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability. (CVE-2018-25011)
A flaw was found in libwebp in versions before 1.0.1. A heap-based buffer overflow in function WebPDecodeRGBInto is possible due to an invalid check for buffer size. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability. (CVE-2020-36328)
A flaw was found in libwebp in versions before 1.0.1. A use-after-free was found due to a thread being killed too early. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability. (CVE-2020-36329)
Note that Nessus has not tested for these issues but has instead relied only on the application’s self-reported version number.
