From Red Hat Security Advisory 2018:3157 :
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 gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.
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. Upstream acknowledges Craig de Stigter as the original reporter of CVE-2018-1000007; Duy Phan Thanh as the original reporter of CVE-2018-1000120; Max Dymond as the original reporter of CVE-2018-1000122; the OSS-fuzz project as the original reporter of CVE-2018-1000301; and Dario Weisser as the original reporter of CVE-2018-1000121.
