Описание
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.
Меры по смягчению последствий
This CVE is mitigated (i.e. not exploitable) by using the openssl package with support for implicit rejection shipped in the following RHEL errata:
