CVE-2005-1589
HighSummary
The pkt_ioctl function in the pktcdvd block device ioctl handler in Linux kernel 2.6.12-rc4 and earlier calls the wrong function before passing an ioctl to the block device, which crosses security boundaries by making kernel address space accessible from user space and allows local users to cause a denial of service and possibly execute arbitrary code.
Risk Assessment
The risk includes potential privilege escalation by a local user, which could lead to system compromise or denial of service.
Recommendation
It is recommended to immediately update the Linux kernel to a version later than 2.6.12-rc4, which addresses this vulnerability.

MISP contains an authentication bypass vulnerability in its LDAP and LinOTP authentication components due to insufficient validation of user-supplied credentials. An attacker knowing a valid directory user's email address could submit an empty password, which may be accepted by an LDAP server allowing unauthenticated binds. Additionally, in the LinOTP component, empty passwords could be checked against local MISP password hashes, and LDAP-provisioned accounts could be created with empty local passwords.

The pkt_ioctl function in the pktcdvd block device ioctl handler (pktcdvd.c) in Linux kernel 2.6.12-rc4 and earlier calls the wrong function before passing an ioctl to the block device, which crosses security boundaries by making kernel address space accessible from user space and allows local users to cause a denial of service and possibly execute arbitrary code, a similar vulnerability to CVE-2005-1264.
