Buffer overflow in efstools in Bonobo, when installed setuid, allows local users to execute arbitrary code via long command line arguments.
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.
Memory leak in ypdbopen in ypdb.c for ypserv before 2.5 in the NIS package 3.9 and earlier allows remote attackers to cause a denial of service (memory consumption) via a large number of requests for a map that does not exist.
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.
Buffer overflow in glob function of glibc allows attackers to cause a denial of service (crash) and possibly execute arbitrary code via a glob pattern that ends in a brace "{" character.
LPRng in Red Hat Linux 7.0 and 7.1 does not properly drop memberships in supplemental groups when lowering privileges, which could allow a local user to elevate privileges.
Buffer overflow in man program in various distributions of Linux allows local user to execute arbitrary code as group man via a long -S option.
Apache on Red Hat Linux with with the UserDir directive enabled generates different error codes when a username exists and there is no publichtml directory and when the username does not exist, which could allow remote attackers to determine valid usernames on the server.
tcl/tk package (tcltk) 8.3.1 searches for its libraries in the current working directory before other directories, which could allow local users to execute arbitrary code via a Trojan horse library that is under a user-controlled directory.
slapd in OpenLDAP 1.x before 1.2.12, and 2.x before 2.0.8, allows remote attackers to cause a denial of service (crash) via an invalid Basic Encoding Rules (BER) length field.
Buffer overflows in the (1) outpack or (2) buf variables of ping in iputils before 20001010, as distributed on Red Hat Linux 6.2 through 7J and other operating systems, may allow local users to gain privileges.
