A race condition in the way envstart and envend pointers are initialized in the execve system call and used in fs/proc/base.c on Linux 2.4 allows local users to cause a denial of service (crash).
Various PDF viewers including (1) Adobe Acrobat 5.06 and (2) Xpdf 1.01 allow remote attackers to execute arbitrary commands via shell metacharacters in an embedded hyperlink.
Kerberos FTP client allows remote FTP sites to execute arbitrary code via a pipe (|) character in a filename that is retrieved by the client.
Buffer overflow in efstools in Bonobo, when installed setuid, allows local users to execute arbitrary code via long command line arguments.
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.
passwd 0.68 does not check the return code for the pamstart function, which has unknown impact and attack vectors that may prevent "safe and proper operation" of PAM.
Memory leak in passwd 0.68 allows local users to cause a denial of service (memory consumption) via a large number of failed read attempts from the password buffer.
Off-by-one error in passwd 0.68 and earlier, when using the --stdin option, causes passwd to use the first 78 characters of a password instead of the first 79, which results in a small reduction of the search space required for brute force attacks.
Format string vulnerability in Speedtouch USB driver before 1.3.1 allows local users to execute arbitrary code via (1) modemrun, (2) pppoa2, or (3) pppoa3.
Buffer overflow in the logging capability for the DHCP daemon (DHCPD) for ISC DHCP 3.0.1rc12 and 3.0.1rc13 allows remote attackers to cause a denial of service (server crash) and possibly execute arbitrary code via multiple hostname options in (1) DISCOVER, (2) OFFER, (3) REQUEST, (4) ACK, or (5) NAK messages, which can generate a long string when writing to a log file.
The DHCP daemon (DHCPD) for ISC DHCP 3.0.1rc12 and 3.0.1rc13, when compiled in environments that do not provide the vsnprintf function, uses C include files that define vsnprintf to use the less safe vsprintf function, which can lead to buffer overflow vulnerabilities that enable a denial of service (server crash) and possibly execute arbitrary code.
