Doc Text:
A timing-based side-channel flaw exists in the perl-Crypt-OpenSSL-RSA package, which could be sufficient to recover plaintext across a network in a Bleichenbacher-style attack. To achieve successful decryption, an attacker would have to be able to send a large number of trial messages. The vulnerability affects the legacy PKCS#1v1.5 RSA encryption padding mode.

Description Mauro Matteo Cascella 2024-03-14 17:37:40 UTC 
A timing based side-channel exists in the perl-Crypt-OpenSSL-RSA package which could be sufficient to recover a plaintext across a network in a Bleichenbacher style attack. To achieve successful decryption an attacker would have to be able to send a large number of trial messages for decryption. The vulnerability affects the legacy PKCS#1v1.5 RSA encryption padding mode.
