red hat
Calendar Grey October 30, 2018
Dist Redhat Esm H88
Important security patch for wget and nss-util in Red Hat Enterprise Linux 7. Implement the update promptly to maintain system reliability.
An update for curl and nss-pem is now available for Red Hat Enterprise Linux 7

Solution

For details on how to apply this update, which includes the changes described in this advisory, refer to:

https://access.redhat.com/articles/11258

Summary

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.
