high Nessus Plugin ID 140801

Language:

Synopsis

The remote Ubuntu host is missing one or more security updates.

Description

The remote Ubuntu 16.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-4541-1 advisory.

 - An issue was discovered in datafile.c in Gnuplot 5.2.5. This issue allows an attacker to conduct a heap- based buffer overflow with an arbitrary amount of data in df_generate_ascii_array_entry. To exploit this vulnerability, an attacker must pass an overlong string as the right bound of the range argument that is passed to the plot function. (CVE-2018-19490)

 - An issue was discovered in post.trm in Gnuplot 5.2.5. This issue allows an attacker to conduct a buffer overflow with an arbitrary amount of data in the PS_options function. This flaw is caused by a missing size check of an argument passed to the set font function. This issue occurs when the Gnuplot postscript terminal is used as a backend. (CVE-2018-19491)

 - An issue was discovered in cairo.trm in Gnuplot 5.2.5. This issue allows an attacker to conduct a buffer overflow with an arbitrary amount of data in the cairotrm_options function. This flaw is caused by a missing size check of an argument passed to the set font function. This issue occurs when the Gnuplot pngcairo terminal is used as a backend. (CVE-2018-19492)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.
