Linux xmonisdn package allows local users to gain root privileges by modifying the IFS or PATH environmental variables.

Buffer overflow in nnrpd program in INN up to version 1.6 allows remote users to execute arbitrary commands.

Buffer overflow in named in BIND 4 versions 4.9.10 and earlier, and 8 versions 8.3.3 and earlier, allows remote attackers to execute arbitrary code via a certain DNS server response containing SIG resource records (RR).

Denial of Service vulnerability in BIND 8 Releases via maliciously formatted DNS messages.

named in ISC BIND 4.9 and 8.1 allows local users to destroy files via a symlink attack on (1) named_dump.db when root kills the process with a SIGINT, or (2) named.stats when SIGIOT is used.

Format string vulnerabilities in the logging routines for dynamic DNS code (print.c) of ISC DHCP daemon (DHCPD) 3 to 3.0.1rc8, with the NSUPDATE option enabled, allow remote malicious DNS servers to execute arbitrary code via format strings in a DNS server response.

Buffer overflow in INN inews program.

Inverse query buffer overflow in BIND 4.9 and BIND 8 Releases.

security flaw

Buffer overflow in DNS resolver functions that perform lookup of network names and addresses, as used in BIND 4.9.8 and ported to glibc 2.2.5 and earlier, allows remote malicious DNS servers to execute arbitrary code through a subroutine used by functions such as getnetbyname and getnetbyaddr.

security flaw

Buffer overflow in the DNS resolver code used in libc, glibc, and libbind, as derived from ISC BIND, allows remote malicious DNS servers to cause a denial of service and possibly execute arbitrary code via the stub resolvers.

ucbmail allows remote attackers to execute commands via shell metacharacters that are passed to it from INN.

Format string vulnerabilities in (1) inews or (2) rnews for INN 2.2.3 and earlier allow local users and remote malicious NNTP servers to gain privileges via format string specifiers in NTTP responses.

security flaw

ISC BIND 9 before 9.2.1 allows remote attackers to cause a denial of service (shutdown) via a malformed DNS packet that triggers an error condition that is not properly handled when the rdataset parameter to the dns_message_findtype() function in message.c is not NULL, aka DoS_findtype.

When compiled with the -DALLOW_UPDATES option, bind allows dynamic updates to the DNS server, allowing for malicious modification of DNS records.

Denial of service in BIND named via maxdname.

security flaw

Buffer overflows in the DNS stub resolver library in ISC BIND 4.9.2 through 4.9.10, and other derived libraries such as BSD libc and GNU glibc, allow remote attackers to execute arbitrary code via DNS server responses that trigger the overflow in the (1) getnetbyname, or (2) getnetbyaddr functions, aka "LIBRESOLV: buffer overrun" and a different vulnerability than CVE-2002-0684.

Buffer overflow in innfeed for ISC InterNetNews (INN) before 2.3.0 allows local users in the "news" group to gain privileges via a long -c command line argument.

Denial of service in BIND named via consuming more than "fdmax" file descriptors.

SIG(0) can be used to exhaust CPU resources

If a server hosts a zone containing a "KEY" Resource Record, or a resolver DNSSEC-validates a "KEY" Resource Record from a DNSSEC-signed domain in cache, a client can exhaust resolver CPU resources by sending a stream of SIG(0) signed requests. This issue affects BIND 9 versions 9.0.0 through 9.11.37, 9.16.0 through 9.16.50, 9.18.0 through 9.18.27, 9.19.0 through 9.19.24, 9.9.3-S1 through 9.11.37-S1, 9.16.8-S1 through 9.16.49-S1, and 9.18.11-S1 through 9.18.27-S1.

A flood of DNS messages over TCP may make the server unstable

A malicious client can send many DNS messages over TCP, potentially causing the server to become unstable while the attack is in progress. The server may recover after the attack ceases. Use of ACLs will not mitigate the attack. This issue affects BIND 9 versions 9.18.1 through 9.18.27, 9.19.0 through 9.19.24, and 9.18.11-S1 through 9.18.27-S1.
