Three security issues were discovered in OpenSSL: A timing attack against ECDSA, a padding oracle in PKCS7_dataDecode() and CMS_decrypt_set1_pkey() and it was discovered that a feature of the random number generator (RNG) intended to protect against shared RNG state between parent and child processes in the event of a fork() syscall was not used by default.Solution
Upgrade the openssl packages.For the oldstable distribution (stretch), these problems have been fixed in version 1.1.0l-1~deb9u1.
For the stable distribution (buster), these problems have been fixed in version 1.1.1d-0+deb10u1.
