Additional details can be found in the upstream advisory: [link moved to references]
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: [link moved to references]");
