According to the version of the libmspack package installed, the EulerOS installation on the remote host is affected by the following vulnerability :

  - chmextract.c in the chmextract sample program, as     distributed with libmspack before 0.8alpha, does not     protect against absolute/relative pathnames in CHM     files, leading to Directory Traversal. NOTE: the vendor     disputes that this is a libmspack vulnerability,     because chmextract.c was only intended as a source-code     example, not a supported application.(CVE-2018-18586)

Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

According to the versions of the libmspack package installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

  - chmd_read_headers in mspack/chmd.c in libmspack before     0.8alpha accepts a filename that has '\0' as its first     or second character (such as the '/\0'     name).(CVE-2018-18585)
