Trustix Secure Linux Security Advisory #2007-0002
Package names: kernel
Summary: Multiple vulnerabilities
Date: 2007-01-05
Affected versions: Trustix Secure Linux 2.2
- --------------------------------------------------------------------------
Package description:
kernel
The kernel package contains the Linux kernel (vmlinuz), the core of
your Trustix Secure Linux operating system. The kernel handles the
basic functions of the operating system: memory allocation, process
allocation, device input and output, etc.
Problem description:
kernel < TSL 2.2 >
- New Upstream.
- SECURITY Fix: A security issue has been reported in Linux kernel
caused due to an error in drivers/isdn/i4l/isdn_ppp.c as the
"isdn_ppp_ccp_reset_alloc_state()" function never initialises an
event timer before scheduling it with the "add_timer()" function.
- The mincore function in kernel does not properly lock access to
user space, which has unspecified impact and attack vectors,
possibly related to a deadlock.
- Another vulnerability has been reported in linux kernel caused due
to a boundary error within the handling of incoming CAPI messages
in net/bluetooth/cmtp/capi.c. This can be exploited to overwrite
certain Kernel data structures.
The Common Vulnerabilities and Exposures project (cve.mitre.org)
has assigned the names CVE-2006-5749, CVE-2006-4814 and CVE-2006-6106
to these issues.
