curl CVE-2019-5443 Local Code Injection Vulnerability

Description

curl is prone to a vulnerability that lets attackers inject and execute arbitrary code. Successfully exploiting this issue may allow attackers to inject and execute arbitrary code. This may lead to other attacks. curl for windows versions prior to 7.65.1_2 are vulnerable.

Recommendations

Permit local access for trusted individuals only. Where possible, use restricted environments and restricted shells.
Ensure that only trusted users have local, interactive access to affected computers.

Run all software as a nonprivileged user with minimal access rights.
To reduce the impact of latent vulnerabilities, always run nonadministrative software as an unprivileged user with minimal access rights.

Do not follow links provided by unknown or untrusted sources.
Web users should be cautious about following links to websites that are provided by unfamiliar or suspicious sources. Filtering HTML from emails may help remove a possible vector for transmitting malicious links to users.

Implement multiple redundant layers of security.
Since this issue may be leveraged to execute code, we recommend memory-protection schemes, such as nonexecutable stack/heap configurations and randomly mapped memory segments. This tactic may complicate exploits of memory-corruption vulnerabilities.

Updates are available. Please see the references or vendor advisory for more information.
