curl vulnerabilities

A security issue affects these releases of Ubuntu and its derivatives:

  • Ubuntu 18.04 LTS
  • Ubuntu 17.10
  • Ubuntu 16.04 LTS
  • Ubuntu 14.04 LTS

Summary

Several security issues were fixed in curl.

Software Description

  • 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)

Max Dymond discovered that curl incorrectly handled certain RTSP responses. If a user or automated system were tricked into connecting to a malicious server, a remote attacker could use this issue to cause curl to crash, resulting in a denial of service, or possibly obtain sensitive information. (CVE-2018-1000301)
