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.

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.

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

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

  - 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 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.
