critical Nessus Plugin ID 183549

Language:

Synopsis

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

Description

The remote Ubuntu 16.04 ESM host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-5172-2 advisory.

 - An issue was discovered in uriparser before 0.9.0. UriQuery.c allows an out-of-bounds write via a uriComposeQuery* or uriComposeQueryEx* function because the '&' character is mishandled in certain contexts. (CVE-2018-19198)

 - An issue was discovered in uriparser before 0.9.0. UriQuery.c allows an integer overflow via a uriComposeQuery* or uriComposeQueryEx* function because of an unchecked multiplication. (CVE-2018-19199)

 - An issue was discovered in uriparser before 0.9.0. UriCommon.c allows attempted operations on NULL input via a uriResetUri* function. (CVE-2018-19200)

 - URI_FUNC() in UriParse.c in uriparser before 0.9.1 has an out-of-bounds read (in uriParse*Ex* functions) for an incomplete URI with an IPv6 address containing an embedded IPv4 address, such as a //[::44.1 address. (CVE-2018-20721)

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

Solution

Update the affected liburiparser-dev and / or liburiparser1 packages.
