Insight
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:
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) these problems have been fixed in version 2.4.19-0.020911.1.woody3 of mips images and version 2.4.19-4.woody1 of kernel source.
For the unstable distribution (sid) this problem will be fixed soon with the next upload of a 2.4.19 kernel image and in version 2.4.22-0.030928.3 for 2.4.22.
We recommend that you upgrade your Linux kernel packages immediately.
