UNKNOWN Summary
SystemTap 1.4, when unprivileged (aka stapusr) mode is enabled, allows local users to cause a denial of service (divide-by-zero error and OOPS) via a crafted ELF program with DWARF expressions that are not properly handled by a stap script that performs stack unwinding (aka backtracing).

NASL family CentOS Local Security Checks NASL id CENTOS_RHSA-2011-0841.NASL description Updated systemtap packages that fix one security issue are now available for Red Hat Enterprise Linux 5. The Red Hat Security Response Team has rated this update as having moderate security impact. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available from the CVE link in the References section. SystemTap is an instrumentation system for systems running the Linux kernel, version 2.6. Developers can write scripts to collect data on the operation of the system. A divide-by-zero flaw was found in the way SystemTap handled malformed debugging information in DWARF format. When SystemTap unprivileged mode was enabled, an unprivileged user in the stapusr group could use this flaw to crash the system. Additionally, a privileged user (root, or a member of the stapdev group) could trigger this flaw when tricked into instrumenting a specially crafted ELF binary, even when unprivileged mode was not enabled. (CVE-2011-1769) SystemTap users should upgrade to these updated packages, which contain a backported patch to correct this issue. last seen 2020-06-01 modified 2020-06-02 plugin id 67083 published 2013-06-29 reporter This script is Copyright (C) 2013-2019 and is owned by Tenable, Inc. or an Affiliate thereof. source https://www.tenable.com/plugins/nessus/67083 title CentOS 5 : systemtap (CESA-2011:0841) NASL family Fedora Local Security Checks NASL id FEDORA_2011-7289.NASL description Two divide-by-zero flaws were found in the way systemtap interpreted certain corrupted DWARF expressions. A privileged user able to execute arbitrary systemtap scripts could be tricked into triggering this flaw to crash the target machine. An unprivileged user (in the stapusr group) may be able to trigger this flaw to crash the target machine, only if unprivileged mode was enabled by the system administrator.

Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues. last seen 2020-06-01 modified 2020-06-02 plugin id 54835 published 2011-05-27 reporter This script is Copyright (C) 2011-2019 and is owned by Tenable, Inc. or an Affiliate thereof. source https://www.tenable.com/plugins/nessus/54835 title Fedora 13 : systemtap-1.4-6.fc13 (2011-7289) NASL family Oracle Linux Local Security Checks NASL id ORACLELINUX_ELSA-2011-0842.NASL description From Red Hat Security Advisory 2011:0842 : Updated systemtap packages that fix two security issues are now available for Red Hat Enterprise Linux 6.
