Debian DSA-441-1 : linux-kernel-2.4.17-mips+mipsel - missing function return value check

Paul Starzetz and Wojciech Purczynski of isec.pl discovered a critical security vulnerability in the memory management code of Linux inside the mremap2 system call. Due to missing function return value check of internal functions a local attacker can gain root privileges. %NASLMINLEVEL 70300 C...

Paul Starzetz and Wojciech Purczynski of isec.pl discovered a critical security vulnerability in the memory management code of Linux inside the mremap2 system call. Due to missing function return value check of internal functions a local attacker can gain root privileges. %NASLMINLEVEL 70300 C...

Debian DSA-514-1 : kernel-image-sparc-2.2 - failing function and TLB flush

Paul Starzetz and Wojciech Purczynski of isec.pl discovered a critical security vulnerability in the memory management code of Linux inside the mremap2 system call. Due to flushing the TLB Translation Lookaside Buffer, an address cache too early it is possible for an attacker to trigger a local...

Debian DSA-440-1 : linux-kernel-2.4.17-powerpc-apus - several vulnerabilities

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...

CVE-2004-0077

CVE-2004-0077 corresponds to a bounds-checking flaw in the Linux kernel mremap implementation (2.2 to 2.6.2). The issue arises when do_munmap return value is not properly checked after exceeding the maximum VMA descriptors, enabling a local attacker to gain root privileges. Connected advisories c...

CVE-2003-0985

CVE-2003-0985 affects Linux kernel 2.4.x (pre-2.4.21, possibly before 2.4.24). The do_mremap path lacks proper bounds checking, enabling local users to cause a denial of service and potentially gain privileges by remapping a VMA to a zero-length VMA. Connected data confirms CVE-2005-0528 is a dup...

Mandrake Linux Security Advisory : kernel (MDKSA-2004:015)

Paul Staretz discovered a flaw in return value checking in the mremap function in the Linux kernel, versions 2.4.24 and previous that could allow a local user to obtain root privileges. A vulnerability was found in the R128 DRI driver by Alan Cox. This could allow local privilege escalation. A fl...

Linux kernel mremap(2) system call does not properly check return value from do_munmap() function

Overview A vulnerability in the Linux mremap2 system call could allow an authenticated, local attacker to execute arbitrary code with root privileges. Description The Linux kernel uses a linked list of vitrual memory area VMA descriptors to reference valid regions of the page table for a given...

CVE-2004-0077

The domremap function for the mremap system call in Linux 2.2 to 2.2.25, 2.4 to 2.4.24, and 2.6 to 2.6.2, does not properly check the return value from the domunmap function when the maximum number of VMA descriptors is exceeded, which allows local users to gain root privileges, a different...

Kernel security update

New kernels are available for Slackware 9.1 and -current to fix a bounds-checking problem in the kernel's mremap call which could be used by a local attacker to gain root privileges. Please note that this is not the same issue as CAN-2003-0985 which was fixed in early January. The kernels in...
