A vulnerability classified as critical was found in Linux Kernel 2.2.x/2.4.x (Operating System). Affected by this vulnerability is an unknown code block of the component ptrace. The manipulation with an unknown input leads to a memory corruption vulnerability. The CWE definition for the vulnerability is CWE-119. The product performs operations on a memory buffer, but it can read from or write to a memory location that is outside of the intended boundary of the buffer. As an impact it is known to affect confidentiality, integrity, and availability. The summary by CVE is:
The kernel module loader in Linux kernel 2.2.x before 2.2.25, and 2.4.x before 2.4.21, allows local users to gain root privileges by using ptrace to attach to a child process that is spawned by the kernel.
The weakness was shared 03/17/2003 by Andrzej Szombierski with Kernel.org (Website). It is possible to read the advisory at marc.theaimsgroup.com. This vulnerability is known as CVE-2003-0127 since 03/13/2003. Access to the local network is required for this attack. The exploitation doesn't need any form of authentication. Technical details are unknown but a public exploit is available.
It is declared as proof-of-concept. We expect the 0-day to have been worth approximately $25k-$100k. The vulnerability scanner Nessus provides a plugin with the ID 15113 (Debian DSA-276-1 : linux-kernel-s390 - local privilege escalation), which helps to determine the existence of the flaw in a target environment. It is assigned to the family Debian Local Security Checks. The security flaw can be detected with the following NASL code:
if (deb_check(release:"3.0", prefix:"kernel-headers-2.4.17", reference:"2.4.17-0.020226.2.woody1")) flag++; if (deb_check(release:"3.0", prefix:"kernel-headers-2.4.19", reference:"2.4.19-0.020911.1.woody1")) flag++; if (deb_check(release:"3.0", prefix:"kernel-image-2.4.17-r3k-kn02", reference:"2.4.17-0.020226.2.woody1")) flag++; if (deb_check(release:"3.0", prefix:"kernel-image-2.4.17-r4k-ip22", reference:"2.4.17-0.020226.2.woody1")) flag++; if (deb_check(release:"3.0", prefix:"kernel-image-2.4.17-r4k-kn04", reference:"2.4.17-0.020226.2.woody1")) flag++; if (deb_check(release:"3.0", prefix:"kernel-image-2.4.17-r5k-ip22", reference:"2.4.17-0.020226.2.woody1")) flag++; if (deb_check(release:"3.0", prefix:"kernel-image-2.4.19-r4k-ip22", reference:"2.4.19-0.020911.1.woody1")) flag++; if (deb_check(release:"3.0", prefix:"kernel-image-2.4.19-r5k-ip22", reference:"2.4.19-0.020911.1.woody1")) flag++; if (deb_check(release:"3.0", prefix:"kernel-patch-2.4.17-mips", reference:"2.4.17-0.020226.2.woody1")) flag++; if (deb_check(release:"3.0", prefix:"kernel-patch-2.4.19-mips", reference:"2.4.19-0.020911.1.woody1")) flag++; if (deb_check(release:"3.0", prefix:"mips-tools", reference:"2.4.17-0.020226.2.woody1")) flag++; if (flag) { if (report_verbosity > 0) security_hole(port:0, extra:deb_report_get()); else security_hole(0); exit(0); }
