Linux kernel ia64 information disclosure
| linux-ia64-info-disclosure (16644) |  Medium Risk |
Description:
Linux kernel could allow a local attacker to obtain sensitive information, caused by a floating point leak. An attacker could create a malicious program that sets the MFH bit, which would allow the attacker to view the registers of another process.
Consequences:
Obtain Information
Remedy:
For Mandrake Linux:
Upgrade to the latest kernel package, as listed below. Refer to MandrakeSoft Security Advisory MDKSA-2004:066 : kernel for more information. See References.

Mandrake Linux 9.2: 2.4.22.36mdk-1-1mdk or later
Mandrake Linux Multi Network Firewall 8.2: 2.4.19.43mdk-1-1mdk or later
Mandrake Linux Corporate Server 2.1: 2.4.19.43mdk-1-1mdk or later
Mandrake Linux 10.0: 2.4.25.7mdk-1-1mdk or later
For Gentoo Linux:
Upgrade to the latest version of kernel, as listed in GLSA 200407-16. See References.
For Trustix Secure Linux:
Upgrade to the latest kernel package, as listed below. Refer to Trustix Secure Linux Security Advisory #2004-0041 for more information. See References.
