The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - The icaltime_from_string function in libical 0.47 and 1.0 allows remote attackers to cause a denial of     service (out-of-bounds heap read) via a crafted string to the icalparser_parse_string function.
    (CVE-2016-5827)

Note that Nessus relies on the presence of the package as reported by the vendor.

This update for libical fixes the following issues: Security issues fixed :

  - CVE-2016-5824: libical 1.0 allows remote attackers to     cause a denial of service (use-after-free) via a crafted     ics file. (bsc#986639)

  - CVE-2016-5827: The icaltime_from_string function in     libical 0.47 and 1.0 allows remote attackers to cause a     denial of service (out-of-bounds heap read) via a     crafted string to the icalparser_parse_string function.
    (bsc#986631)

  - CVE-2016-9584: libical allows remote attackers to cause     a denial of service (use-after-free) and possibly read     heap memory via a crafted ics file. (bsc#1015964) Bug     fixes :

  - libical crashes while parsing timezones (bsc#1044995)
