A medium-severity security flaw in perl-Crypt-OpenSSL-RSA. There are no confirmed reports of exploitation so far. The chance it is exploited in the next 30 days is estimated at 0.5% (higher than 44% of all known vulnerabilities). Fixed versions are available - upgrade the affected package.
Official description
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.
