Multiple unknown vulnerabilities in Linux kernel 2.4 and 2.6 allow local users to gain privileges or access kernel memory, as found by the Sparse source code checking tool.

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.

Progress Database 9.1 to 9.1D06 trusts user input to find and load libraries using dlopen, which allows local users to gain privileges via (1) a PATH environment variable that points to malicious libraries, as demonstrated using libjutil.so in_proapsv, or (2) the -installdir command line parameter, as demonstrated using librocket_r.so in _dbagent.
