Mandrake Linux Security Advisory : gnupg (MDKSA-2001:053-1)
High Nessus Plugin ID 13870
SynopsisThe remote Mandrake Linux host is missing a security update.
DescriptionA format string vulnerability exists in gnupg 1.0.5 and previous versions which is fixed in 1.0.6. This vulnerability can be used to invoke shell commands with privileges of the currently logged-in user.
The /usr/bin/gpg executable was installed setuid root and setgid root.
While being setuid root offers locking pages in physical memory to avoid writing sensitive material to swap and is of benefit, being setgid root provides no benefits and allows users to write to files that have group root access. This update strips the setgid bit from /usr/bin/gpg.
SolutionUpdate the affected gnupg package.
