Package : openssl
CVE ID : CVE-2021-4160 CVE-2022-0778
Debian Bug : 989604
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.
