Detail
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: 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 2.4.17-4 of powerpc/apus images. Other architectures will probably mentioned in a separate advisory or are not affected (m68k). For the unstable distribution (sid) this problem will be fixed soon. We recommend that you upgrade your Linux kernel packages immediately. |

3986 | Linux Kernel mremap() Missing Return Value Checking
Privilege Escalation The Linux kernel contains a flaw that may allow a malicious user to gain access to unauthorized privileges due to improper checks on return values performed in the do_mremap function for the mremap system call. This flaw may lead to a loss of Confidentiality, Integrity and Availability. |
3315 | Linux Kernel do_mremap() Privilege Escalation A local overflow exists in the Linux kernel. The do_mremap() function fails to perform bounds checking resulting in a buffer overflow. With a specially crafted request, an attacker can execute arbitrary code resulting in a loss of confidentiality, integrity, and/or availability. |
2887 | Linux Kernel do_brk local Overflow A flaw exists in the Linux kernel which allows a local user to map kernel memory segments into an unprivileged process. Specifically, the do_brk function does not verify that the allocated memory range does not exceed the TASK_SIZE constant. The do_brk function is called by the ELF executable loader and the mmap system call, however only the mmap method is exploitable. Once kernel memory access has been obtained, a number of tricks can be used to gain superuser privileges. |
