Package : kernel-image-2.4.17-hppa
Vulnerability : several vulnerabilities
Problem-Type : local
Debian-specific: no
CVE ID : CAN-2003-0961 CAN-2003-0985 CAN-2004-0077
Several local root exploits have been discovered recently in the Linux
kernel. This security advisory updates the mips kernel 2.4.19 for
Debian GNU/Linux. The Common Vulnerabilities and Exposures project
identifies the following problems that are fixed with this update:
CAN-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.
CAN-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.
CAN-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) these problems have been fixed in
version 32.3 of kernel-image-2.4.17-hppa.
For the unstable distribution (sid) these problems have been fixed in
version 2.4.25-1 of kernel-image-2.4.25-hppa.
We recommend that you upgrade your Linux kernel packages immediately.
