RHEL 7 : curl and nss-pem (RHSA-2018:3157)

critical Nessus Plugin ID 118532

Language:

Synopsis

The remote Red Hat host is missing one or more security updates for curl / nss-pem.

Description

The remote Redhat Enterprise Linux 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2018:3157 advisory.

The curl packages provide the libcurl library and the curl utility for downloading files from servers using various protocols, including HTTP, FTP, and LDAP.

The nss-pem package provides the PEM file reader for Network Security Services (NSS) implemented as a PKCS#11 module.

Security Fix(es):

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

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

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

For more details about the security issue(s), including the impact, a CVSS score, and other related information, refer to the CVE page(s) listed in the References section.
