K97324400: OpenSSL vulnerability CVE-2019-1563
Original Publication Date: 10 Oct, 2019
Security Advisory Description
In situations where an attacker receives automated notification of the success
or failure of a decryption attempt an attacker, after sending a very large
number of messages to be decrypted, can recover a CMS/PKCS7 transported
encryption key or decrypt any RSA encrypted message that was encrypted with the
public RSA key, using a Bleichenbacher padding oracle attack. Applications are
not affected if they use a certificate together with the private RSA key to the
CMS_decrypt or PKCS7_decrypt functions to select the correct recipient info to
decrypt. Fixed in OpenSSL 1.1.1d (Affected 1.1.1-1.1.1c). Fixed in OpenSSL
1.1.0l (Affected 1.1.0-1.1.0k). Fixed in OpenSSL 1.0.2t (Affected
1.0.2-1.0.2s). (CVE-2019-1563)
Impact
Attackers may be able to recover a CMS/PKCS7 transported encryption key or
decrypt RSA encrypted messages that were encrypted with the public RSA key.
