Red Hat Product Errata RHSA-2011:0017 normal SHIPPED_LIVE Important: Red Hat Enterprise Linux 5.6 kernel security and bug fix update 2011-01-13 10:37:42 UTC

Description Petr Matousek 2010-11-01 21:27:08 UTC
Description of problem:
The SNDRV_HDSP_IOCTL_GET_CONFIG_INFO ioctl in hdspm.c allows unprivileged users to read uninitialized kernel stack memory, because several fields of the hdspm_config_info structs declared on the stack are not altered or zeroed before being copied back to the user. 



Red Hat would like to thank Dan Rosenberg for reporting this issue.

Comment 2 Petr Matousek 2010-11-02 11:18:03 UTC

This issue did not affect the versions of Linux kernel as shipped with Red Hat
Enterprise Linux 3 and 4 as they did not include support for RME Hammerfall DSP
MADI Audio interface.
