Systemtap Security Vulnerabilities

CVE-2012-0875

SystemTap 1.7, 1.6.7, and probably other versions, when unprivileged mode is enabled, allows local users to obtain sensitive information from kernel memory or cause a denial of service (kernel panic and crash) via vectors related to crafted DWARF data, which triggers a read of an invalid...

CVE-2011-2503

The insert_module function in runtime/staprun/staprun_funcs.c in the systemtap runtime tool (staprun) in SystemTap before 1.6 does not properly validate a module when loading it, which allows local users to gain privileges via a race condition between the signature validation and the module...

CVE-2011-2502

runtime/staprun/staprun_funcs.c in the systemtap runtime tool (staprun) in SystemTap before 1.6 does not properly validate modules when a module path is specified by a user for user-space probing, which allows local users in the stapusr group to gain privileges via a crafted module in the search...

CVE-2011-1769

SystemTap 1.4 and earlier, 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 context variable...

CVE-2011-1781

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...

CVE-2010-4170

The staprun runtime tool in SystemTap 1.3 does not properly clear the environment before executing modprobe, which allows local users to gain privileges by setting the MODPROBE_OPTIONS environment variable to specify a malicious configuration...

CVE-2010-4171

The staprun runtime tool in SystemTap 1.3 does not verify that a module to unload was previously loaded by SystemTap, which allows local users to cause a denial of service (unloading of arbitrary kernel...

CVE-2010-0412

stap-server in SystemTap 1.1 does not properly restrict the value of the -B (aka BUILD) option, which allows attackers to have an unspecified impact via vectors associated with executing the make program, a different vulnerability than...

CVE-2010-0411

Multiple integer signedness errors in the (1) __get_argv and (2) __get_compat_argv functions in tapset/aux_syscalls.stp in SystemTap 1.1 allow local users to cause a denial of service (script crash, or system crash or hang) via a process with a large number of arguments, leading to a buffer...

CVE-2009-4273

stap-server in SystemTap before 1.1 allows remote attackers to execute arbitrary commands via shell metacharacters in stap command-line arguments in a...

CVE-2009-2911

SystemTap 1.0, when the --unprivileged option is used, does not properly restrict certain data sizes, which allows local users to (1) cause a denial of service or gain privileges via a print operation with a large number of arguments that trigger a kernel stack overflow, (2) cause a denial of...

CVE-2009-0784

Race condition in the SystemTap stap tool 0.0.20080705 and 0.0.20090314 allows local users in the stapusr group to insert arbitrary SystemTap kernel modules and gain privileges via unknown...
