Security Bulletin
Summary
IBM has provided explicit mitigation for the following Kerberos CVEs. DataPower did not previously provide the conditions necessary to exploit these CVEs. The explicit mitigations provided here protect against possible future changes that might have made them exploitable.
Vulnerability Details
CVEID: CVE-2014-5352
DESCRIPTION: MIT krb5 could allow a remote authenticated attacker to execute arbitrary code on the system,, caused by a double-free error in gss_process_context_token(). An attacker could exploit this vulnerability to execute arbitrary code on the system.
CVSS Base score: 9
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/100842 for the current score.
CVSS Vector: (AV:N/AC:L/Au:S/C:C/I:C/A:C)
CVEID: CVE-2014-4344
DESCRIPTION: MIT Kerberos 5 (krb5) is vulnerable to a NULL pointer dereference in the acc_ctx_cont() function within the SPNEGO Acceptor for Continuation Tokens. By sending a specially-crafted request, an attacker could exploit this vulnerability to cause the application to crash.
CVSS Base score: 5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/95210 for the current score.
CVSS Vector: (AV:N/AC:L/Au:N/C:N/I:N/A:P)
