During the certificate validation process, bouncycastle used the certificate's 'Subject Name' into an LDAP search filter without any escaping.

CVE-2023-33201

Bouncy Castle For Java before 1.74 is affected by an LDAP injection vulnerability. The vulnerability only affects applications that use an LDAP CertStore from Bouncy Castle to validate X.509 certificates. During the certificate validation process, Bouncy Castle inserts the certificate's Subject Name into an LDAP search filter without any escaping, which leads to an LDAP injection vulnerability.

For Debian 10 Buster, this problem has been fixed in version 1.60-1+deb10u1.

We recommend that you upgrade your bouncycastle packages.
