IBM Platform Symphony 7.1 Interim Fix 366258 Readme File

Abstract

This fix resolves the VEMKD core dumping if there is a long value for the client name attribute in vem_register().

Description

The length of the client name attribute used in the vem_register() call to VEMKD causes the system to core dump. If the client name value is greater than 60, it overflows the buffer and causes memory corruption for VEMKD.

With this fix, the limitation of 60 characters has been extended to 256. Additionally, if the client name is greater than 256 characters, an error displays, rather than causing a core dump.

This interim fix applies only to the following platform:

Linux2.6-glibc2.3-x86_64
