FreeBSD : automake -- Insecure 'distcheck' recipe granted world-writable distdir (36235c38-e0a8-11e1-9f4d-002354ed89bc)
Medium Nessus Plugin ID 61451
SynopsisThe remote FreeBSD host is missing a security-related update.
DescriptionGNU reports :
The recipe of the 'distcheck' target granted temporary world-write permissions on the extracted distdir. This introduced a locally exploitable race condition for those who run 'make distcheck' with a non-restrictive umask (e.g., 022) in a directory that was accessible by others. A successful exploit would result in arbitrary code execution with the privileges of the user running 'make distcheck'.
It is important to stress that this vulnerability impacts not only the Automake package itself, but all packages with Automake-generated makefiles. For an effective fix it is necessary to regenerate the Makefile.in files with a fixed Automake version.
SolutionUpdate the affected package.
