(RHSA-2018:3157) Moderate: curl and nss-pem security and bug fix update

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)
