Tavis Ormandy discovered that the BN_mod_sqrt() function of OpenSSL could be tricked into an infinite loop. This could result in denial of service via malformed certificates. Additional details can be found in the upstream advisory: https://www.openssl.org/news/secadv/20220315.txt In addition this update corrects a carry propagation bug specific to MIPS architectures. For the oldstable distribution (buster), this problem has been fixed in version 1.1.1d-0+deb10u8. For the stable distribution (bullseye), this problem has been fixed in version 1.1.1k-1+deb11u2. We recommend that you upgrade your openssl packages. For the detailed security status of openssl please refer to its security tracker page at: https://security-tracker.debian.org/tracker/openssl
