I reviewed libtraceevent 1:1.8.2-1 as checked into noble. This shouldn't be
considered a full audit but rather a quick gauge of maintainability.
> libtraceevent - Linux kernel trace event library
- CVE History:
- none
- Build-Depends?
- nothing concerning
- most dependencies are for building documentation
- pre/post inst/rm scripts?
- none
- init scripts?
- none
- systemd units?
- none
- dbus services?
- none
- setuid binaries?
- none
- binaries in PATH?

- polkit files?
- none
- udev rules?
- none
- cron jobs?
- none
- unit tests / autopkgtests?
- in progress by owning team
- Build logs:
- missing MAN pages
- documentation warnings make build logs noisy
- W: libtraceevent source: build-depends-on-obsolete-package Build-Depends:
pkg-config => pkgconf
- Processes spawned?
- ./src/parse-filter.c runs regexec
- this is a library, secure implementation depends on downstream projects
- Memory management?
- heavy use
- care seems to be taken
- as a root process, bugs are unlikely to cause vulnerabilities
- this is a library, secure implementation depends on downstream projects
- File IO?
- load_plugin() from ./src/event-plugin.c use dlopen
- security depends on how downstream projects load plugins
- assume plugins are root
- Logging?
- contains error handling messages
- mostly in ./src/parse-filter.c
- Environment variable usage?
- TRACEEVENT_PLUGIN_DIR
- HOME
- Use of privileged functions?
- none
- Use of cryptography / random number sources etc?
- none
- Use of temp files?
- none
- Use of networking?
- minimal use in ./src/event-parse.c
- Use of WebKit?
- none
- Use of PolicyKit?
- none
- Any significant cppcheck and Coverityresults?
- false positives
- these looked relevant at first glance, but not after analysis
- Any significant shellcheck results?
- none, all reports are for manpages/tests/building
- Any significant bandit results?
- none
Security team ACK for promoting libtraceevent to main.
