16 May 2018
Several security issues were fixed in curl.
Releases
Packages
- curl - HTTP, HTTPS, and FTP client and client libraries
Details
Dario Weisser discovered that curl incorrectly handled long FTP server
command replies. If a user or automated system were tricked into connecting
to a malicious FTP server, a remote attacker could use this issue to cause
curl to crash, resulting in a denial of service, or possibly execute
arbitrary code. This issue only affected Ubuntu 17.10 and Ubuntu 18.04 LTS.
(CVE-2018-1000300)
