Mandriva Linux Security Advisory 2010-038 – main.C in maildrop 2.3.0 and earlier, when run by root with the -d option, uses the gid of root for execution of the.mailfilter file in a user’s home directory, which allows local users to gain privileges via a crafted file. The updated packages have been patched to correct this issue.
