curl: Incorrect fix for CVE-2021-22898 TELNET stack contents disclosure

A flaw was found in the way curl handled telnet protocol option for sending environment variables, which could lead to sending of uninitialized data from a stack-based buffer to the server. This issue leads to potentially revealing sensitive internal information to the server using a clear-text...

curl supports the `-t` command line option known as `CURLOPT_TELNETOPTIONS`in libcurl. This rarely used option is used to send variable=content pairs toTELNET servers.Due to flaw in the option parser for sending `NEW_ENV` variables libcurlcould be made to pass on uninitialized data from a stack based buffer to theserver. Therefore potentially revealing sensitive internal information to theserver using a clear-text network protocol.This could happen because curl did not call and use sscanf() correctly whenparsing the string provided by the application.

kernel/bpf/verifier.c in the Linux kernel through 5.12.1 performs undesirable speculative loads leading to disclosure of stack content via side-channel attacks aka CID-801c6058d14a. The specific concern is not protecting the BPF stack area against speculative loads. Also the BPF stack can contain uninitialized data that might represent sensitive information previously operated on by the kernel.
