Hello,
I noticed that the version of OpenSSL in this repo is subject to a recent security vulnerability (https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2021-3449). The issue can be resolved by updating to the latest version of OpenSSL or applying the following patch to ssl/statem/extensions.c (the line numbers in the patch might not exactly line up depending on what version of OpenSSL you have):
@@ -1137,8 +1137,9 @@
static int init_sig_algs(SSL *s, unsigned int context)

/* Clear any signature algorithms extension received */
OPENSSL_free(s->s3->tmp.peer_sigalgs);
s->s3->tmp.peer_sigalgs = NULL;
+ s->s3->tmp.peer_sigalgslen = 0;
return 1;
}
请问什么时候更新openssl版本到version 1_1_1 ? 目前的版本1_0_2存在安全漏洞.
I get the following error when I try to run the below code for a DTLS client server program using rust through visual studio code and its terminal. I have already installed openssl libraries using vcpkg and set the environment variables. I have also installed the c/c++ extensions for vscode.
Error: error: could not find native static library C, perhaps an -L flag is missing?
How do I resolve this error? My DTLS code is given below along with build.rs and cargo.toml. I get the same error when I try to run any openssl-dependant codes in C/C++/Rust.
