>> Openwsman Buffer Overflow and SSL Session Replay Vulnerabilities
|
Two vulnerabilities have been identified in Openwsman, which could be exploited by remote attackers to bypass security restrictions, cause a denial of service or compromise a vulnerable system.
The first issue is caused by buffer overflow errors in the "ws_base64_decode()" function when decoding HTTP basic authentication headers, which could be exploited by remote unauthenticated attackers to crash an affected implementation or execute arbitrary code.
The second vulnerability is caused by an error in the "callback-verify" function within the OpenSSL library that does not verify the host providing a certificate while verifying the fingerprint of the received certificate, which could be exploited to conduct SSL session replay attacks against a client.
