curl vulnerabilities ==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 14.04 ESM - Ubuntu 12.04 ESM
Summary:
Several security issues were fixed in curl.
Software Description: - curl: HTTP, HTTPS, and FTP client and client libraries
Details:
USN-4665-1 fixed several vulnerabilities in curl. This update provides the corresponding update for Ubuntu 12.04 ESM and Ubuntu 14.04 ESM.
Original advisory details:
Varnavas Papaioannou discovered that curl incorrectly handled FTP PASV responses. An attacker could possibly use this issue to trick curl into connecting to an arbitrary IP address and be used to perform port scanner and other information gathering. (CVE-2020-8284)
It was discovered that curl incorrectly handled FTP wildcard matchins. A remote attacker could possibly use this issue to cause curl to consume resources and crash, resulting in a denial of service. (CVE-2020-8285)
Update instructions:
The problem can be corrected by updating your system to the following package versions:
Ubuntu 14.04 ESM: curl 7.35.0-1ubuntu2.20+esm6 libcurl3 7.35.0-1ubuntu2.20+esm6 libcurl3-gnutls 7.35.0-1ubuntu2.20+esm6 libcurl3-nss 7.35.0-1ubuntu2.20+esm6
Ubuntu 12.04 ESM: curl 7.22.0-3ubuntu4.29 libcurl3 7.22.0-3ubuntu4.29 libcurl3-gnutls 7.22.0-3ubuntu4.29 libcurl3-nss 7.22.0-3ubuntu4.29
