Vulnerabilidades

Local user gains root privileges via buffer overflow in rdist, via lookup() function.

cpio on FreeBSD 2.1.0, Debian GNU/Linux 3.0, and possibly other operating systems, uses a 0 umask when creating files using the -O (archive) or -F options, which creates the files with mode 0666 and allows local users to read or overwrite those files.

Local user gains root privileges via buffer overflow in rdist, via expstr() function.

The suidperl and sperl program do not give up root privileges when changing UIDs back to the original users, allowing root access.

Manual page reader (man) in FreeBSD 2.2 and earlier allows local users to gain privileges via a sequence of commands.

Vulnerability in BSD Telnet client with encryption and Kerberos 4 authentication allows remote attackers to decrypt the session via sniffing.

Buffer overflow in FreeBSD libmytinfo library allows local users to execute commands via a long TERMCAP environmental variable.

Buffer overflow in passwd in BSD based operating systems 4.3 and earlier allows local users to gain root privileges by specifying a long shell or GECOS field.
