(HP Issues Warning for JetDirect Print Servers) OpenSSL Has Multiple Buffer Overflows That Allow Remote Users to Execute Arbitrary Code with Root Privileges
SecurityTracker Alert ID:  1005144
SecurityTracker URL:  http://securitytracker.com/id/1005144
CVE Reference:   CVE-2002-0655, CVE-2002-0656, CVE-2002-0657, CVE-2002-0659   (Links to External Site)
Date:  Aug 27 2002
Impact:   Denial of service via network, Execution of arbitrary code via network, Root access via network, User access via network
Fix Available:  Yes  Vendor Confirmed:  Yes  
Version(s): X.22.00 through X.23.99 ( where X = L through U )
Description:   Four buffer overflow conditions were reported in OpenSSL. All four may allow a remote user to execute arbitrary code. HP reports that JetDirect Print Servers are affected.

The vendor has reported that A.L. Digital Ltd and The Bunker have uncovered multiple buffer overflows in OpenSSL, discovered during a security review.

A remote user could create a specially crafted, oversized client master key and use SSL2 to trigger an overflow on an SSL server. According to the report, this vulnerability was independently discovered by Neohapsis, which has confirmed that the overflow can be exploited to execute arbitrary code.

A remote user with an SSL server could create a specially crafted, oversized session ID and supply this ID to a target client using SSL3 to trigger an overflow.

A remote user could supply a specially crafted, oversized master key to an SSL3 server to trigger an overflow. It is reported that this flaw affects OpenSSL 0.9.7 prior to version 0.9.7-beta3 when Kerberos is enabled.

Several buffers used for ASCII representations of integers are reportedly too small on 64 bit platforms.

The report also states that other potential buffer overflows that are currently considered to be non-exploitable have been discovered.

The vendor notes that Adi Stav and James Yonan independently reported that the ASN1 parser can be confused by certain invalid encodings, potentially allowing a remote user to cause denial of service conditions. An OpenSSL-based application that use the ASN1 library to parse untrusted data (including all SSL or TLS applications using S/MIME [PKCS#7] or certificate generation routines) are affected.

Impact:   A remote user acting as an SSL client could execute arbitrary code on an SSL server. A remote user acting as an SSL server could cause arbitrary code to be executed on an SSL client that is connecting to the server. In each case, the code would run with privileges of the affected implementation.

A remote user may be able cause denial of service conditions.

Solution:   No solution was available at the time of this entry.

HP recommends that users disable the Embedded Web Server on affected JetDirect Print Servers until the fixed version of firmware is available.
