MandrakeSoft Mandrake Linux 8.1

Off-by-one error in the channel code of OpenSSH 2.0 through 3.0.2 allows local users or remote malicious servers to gain privileges.

Kerberos FTP client allows remote FTP sites to execute arbitrary code via a pipe (|) character in a filename that is retrieved by the client.

dvips converter for Postscript files in the tetex package calls the system() function insecurely, which allows remote attackers to execute arbitrary commands via certain print jobs, possibly involving fonts.

Format string vulnerability in stunnel before 3.22 when used in client mode for (1) smtp, (2) pop, or (3) nntp allows remote malicious servers to execute arbitrary code.

Heap corruption vulnerability in the "at" program allows local users to execute arbitrary code via a malformed execution time, which causes at to free the same memory twice.

Packaging error for expect 8.3.3 in Mandrake Linux 8.1 causes expect to search for its libraries in the /home/snailtalk directory before other directories, which could allow a local user to gain root privileges.

setpwnam.c in the util-linux package, as included in Red Hat Linux 7.3 and earlier, and other operating systems, does not properly lock a temporary file when modifying /etc/passwd, which may allow local users to gain privileges via a complex race condition that uses an open file descriptor in utility programs such as chfn and chsh.

The Internet Group Management Protocol (IGMP) allows local users to cause a denial of service via an IGMP membership report to a target's Ethernet address instead of the Multicast group address, which causes the target to stop sending reports to the router and effectively disconnect the group from the network.

The default PAM files included with passwd in Mandrake Linux 8.1 do not support MD5 passwords, which could result in a lower level of password security than intended.

jmcce 1.3.8 in Mandrake 8.1 creates log files in /tmp with predictable names, which allows local users to overwrite arbitrary files via a symlink attack.
