tag_insight = "Several local root exploits have been discovered recently in the Linux
kernel.  This security advisory updates the PowerPC/Apus kernel for
Debian GNU/Linux.  The Common Vulnerabilities and Exposures project
identifies the following problems that are fixed with this update:

CVE-2003-0961:

An integer overflow in brk() system call (do_brk() function) for
Linux allows a local attacker to gain root privileges.  Fixed
upstream in Linux 2.4.23.

CVE-2003-0985:

Paul Starzetz discovered a flaw in bounds checking in mremap() in
the Linux kernel (present in version 2.4.x and 2.6.x) which may
allow a local attacker to gain root privileges.  Version 2.2 is not
affected by this bug.  Fixed upstream in Linux 2.4.24.

CVE-2004-0077:

Paul Starzetz and Wojciech Purczynski of isec.pl discovered a
critical security vulnerability in the memory management code of
Linux inside the mremap(2) system call.  Due to missing function
return value check of internal functions a local attacker can gain
root privileges.  Fixed upstream in Linux 2.4.25 and 2.6.3.

For the stable distribution (woody) this problem has been fixed in
version 2.4.26/20040204 of lart, netwinder and riscpc image and in
version 20040204 of kernel-patch-2.4.16-arm.

Other architectures will probably mentioned in a separate advisory or
are not affected (m68k).

For the unstable distribution (sid) these problems will be fixed soon.

We recommend that you upgrade your Linux kernel packages immediately.";
