Description

This security bulletin contains information about 2 secuirty vulnerabilities.


1) Input validation error (CVE-ID: CVE-2022-35252)

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to the way curl handles cookies with control codes (byte values below 32). When cookies that contain such control codes are later sent back to an HTTP(S) server, it might make the server return a 400 response, effectively allowing a "sister site" to deny service to siblings.


2) Use-after-free (CVE-ID: CVE-2022-43552)

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to a use-after-free error while processing denied requests from HTTP proxies when using SMB or TELNET protocols. A remote attacker can trigger a use-after-free error and crash the application.
