This update for curl fixes the following issues :

  • CVE-2017-1000100: TFP sends more than buffer size and it could lead to a denial of service (bsc#1051644)

  • CVE-2017-7407: ourWriteOut function problem could lead to a heap buffer over-read (bsc#1032309)

  • CVE-2016-9586: libcurl printf issue could lead to buffer overflow (bsc#1015332)

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.
