Detail
| Several local root exploits have been discovered recently in the Linux kernel. This security advisory updates the PA-RISC kernel 2.4.18 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. Please note that the source package has to include a lot of updates in order to compile the package, which wasn't possible with the old source package. For the stable distribution (woody) these problems have been fixed in version 62.1 of kernel-image-2.4.18-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. |

| 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. |
