INFO (CVEs are): strongswan 5.9.1
cves found
CVE-2021-41990
Desc: The gmp plugin in strongSwan before 5.9.4 has a remote integer overflow
via a crafted certificate with an RSASSA-PSS signature. For example, this can
be triggered by an unrelated self-signed CA certificate sent by an initiator.
Remote code execution cannot occur.

Severity: HIGH
CVE-2021-41991
Desc: The in-memory certificate cache in strongSwan before 5.9.4 has a remote
integer overflow upon receiving many requests with different certificates to
fill the cache and later trigger the replacement of cache entries. The code
attempts to select a less-often-used cache entry by means of a random number
generator, but this is not done correctly. Remote code execution might be a
slight possibility.

Severity: HIGH
CVE-2021-45079
Desc: In strongSwan before 5.9.5, a malicious responder can send an EAP-Success
message too early without actually authenticating the client and (in the case
of EAP methods with mutual authentication and EAP-only authentication for
IKEv2) even without server authentication.

Severity: CRITICAL
CVE-2022-40617
Desc: strongSwan before 5.9.8 allows remote attackers to cause a denial of
service in the revocation plugin by sending a crafted end-entity (and
intermediate CA) certificate that contains a CRL/OCSP URL that points to a
server (under the attacker's control) that doesn't properly respond but (for
example) just does nothing after the initial TCP handshake, or sends an
excessive amount of application data.
