New! Plugin Severity Now Using CVSS v3

Synopsis

The remote Red Hat host is missing one or more security updates.

Description

The remote Redhat Enterprise Linux 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2020:0544 advisory.

- curl: HTTP authentication leak in redirects (CVE-2018-1000007)

- curl: FTP path trickery leads to NIL byte out of bounds write (CVE-2018-1000120)

- curl: LDAP NULL pointer dereference (CVE-2018-1000121)

- curl: RTSP RTP buffer over-read (CVE-2018-1000122)

- curl: Out-of-bounds heap read when missing RTSP headers allows information leak or denial of service (CVE-2018-1000301)

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

Solution

Update the affected curl, libcurl and / or libcurl-devel packages.
