1. Summary:

An update for curl and nss-pem is now available for Red Hat Enterprise
Linux 7.

Red Hat Product Security has rated this update as having a security impact
of Moderate. A Common Vulnerability Scoring System (CVSS) base score, which

3. Description:

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.

Red Hat would like to thank the Curl project for reporting these issues.
