"This update for curl fixes the following issues: curl was updated to
version 7.37.0 (fate#325339 bsc#1084137) This update syncs the curl
version to the one in SUSE Linux Enterprise 12 and is full binary
compatible to the previous version. This update is done to allow other
third-party software like 'R' to be able to be used on the SUSE Linux
Enterprise 11 codebase. Following security issues were fixed :

  - CVE-2018-1000120: A buffer overflow exists in the FTP
    URL handling that allowed an attacker to cause a denial
    of service or possible code execution (bsc#1084521).

  - CVE-2018-1000121: A NULL pointer dereference exists in
    the LDAP code that allowed an attacker to cause a denial
    of service (bsc#1084524).

  - CVE-2018-1000122: A buffer over-read exists in the
    RTSP+RTP handling code that allowed an attacker to cause
    a denial of service or information leakage
    (bsc#1084532). The package also requires a libopenssl
    that implements the DEFAULT_SUSE cipher list
    (bsc#1081056, bsc#1083463,bsc#1086825)

Note that Tenable Network Security has extracted the preceding
description block directly from the SUSE security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues."
