Title
simple protocol server ignores accepts unlimited connections and logs failures without limit
Summary
Avahi is a system which facilitates service discovery on a local network via the mDNS/DNS-SD protocol suite. In versions up to and including 0.9-rc2, the simple protocol server ignores the documented client limit and accepts unlimited connections, allowing for easy local DoS. Although `CLIENTS_MAX` is defined, `server_work()` unconditionally `accept()`s and `client_new()` always appends the new client and increments `n_clients`. There is no check against the limit. When client cannot be accepted as a result of maximal socket number of avahi-daemon, it logs unconditionally error per each connection. Unprivileged local users can exhaust daemon memory and file descriptors, causing a denial of service system-wide for mDNS/DNS-SD. Exhausting local file descriptors causes increased system load caused by logging errors of each of request. Overloading prevents glibc calls using nss-mdns plugins to resolve `*.local.` names and link-local addresses. As of time of publication, no known patched versions are available, but a candidate fix is available in pull request 808, and some workarounds are available. Simple clients are offered for nss-mdns package functionality. It is not possible to disable the unix socket `/run/avahi-daemon/socket`, but resolution requests received via DBus are not affected directly. Tools avahi-resolve, avahi-resolve-address and avahi-resolve-host-name are not affected, they use DBus interface. It is possible to change permissions of unix socket after avahi-daemon is started. But avahi-daemon does not provide any configuration for it. Additional access restrictions like SELinux can also prevent unwanted tools to access the socket and keep resolution working for trusted users.

CVE-2021-26720 (GCVE-0-2021-26720)
Vulnerability from nvd – Published: 2021-02-17 21:19 – Updated: 2024-08-03 20:33
VLAI?
Summary
avahi-daemon-check-dns.sh in the Debian avahi package through 0.8-4 is executed as root via /etc/network/if-up.d/avahi-daemon, and allows a local attacker to cause a denial of service or create arbitrary empty files via a symlink attack on files under /run/avahi-daemon. NOTE: this only affects the packaging for Debian GNU/Linux (used indirectly by SUSE), not the upstream Avahi product.
Severity ?
No CVSS data available.

CVE-2017-6519 (GCVE-0-2017-6519)
Vulnerability from nvd – Published: 2017-05-01 01:00 – Updated: 2025-12-03 21:57
VLAI?
Summary
avahi-daemon in Avahi through 0.6.32 and 0.7 inadvertently responds to IPv6 unicast queries with source addresses that are not on-link, which allows remote attackers to cause a denial of service (traffic amplification) and may cause information leakage by obtaining potentially sensitive information from the responding device via port-5353 UDP packets. NOTE: this may overlap CVE-2015-2809.

CVE-2025-59529 (GCVE-0-2025-59529)
Vulnerability from cvelistv5 – Published: 2025-12-18 20:25 – Updated: 2025-12-19 22:04

Title
simple protocol server ignores accepts unlimited connections and logs failures without limit
Summary
Avahi is a system which facilitates service discovery on a local network via the mDNS/DNS-SD protocol suite. In versions up to and including 0.9-rc2, the simple protocol server ignores the documented client limit and accepts unlimited connections, allowing for easy local DoS. Although `CLIENTS_MAX` is defined, `server_work()` unconditionally `accept()`s and `client_new()` always appends the new client and increments `n_clients`. There is no check against the limit. When client cannot be accepted as a result of maximal socket number of avahi-daemon, it logs unconditionally error per each connection. Unprivileged local users can exhaust daemon memory and file descriptors, causing a denial of service system-wide for mDNS/DNS-SD. Exhausting local file descriptors causes increased system load caused by logging errors of each of request. Overloading prevents glibc calls using nss-mdns plugins to resolve `*.local.` names and link-local addresses. As of time of publication, no known patched versions are available, but a candidate fix is available in pull request 808, and some workarounds are available. Simple clients are offered for nss-mdns package functionality. It is not possible to disable the unix socket `/run/avahi-daemon/socket`, but resolution requests received via DBus are not affected directly. Tools avahi-resolve, avahi-resolve-address and avahi-resolve-host-name are not affected, they use DBus interface. It is possible to change permissions of unix socket after avahi-daemon is started. But avahi-daemon does not provide any configuration for it. Additional access restrictions like SELinux can also prevent unwanted tools to access the socket and keep resolution working for trusted users.

Vulnerability from cvelistv5 – Published: 2021-02-17 21:19 – Updated: 2024-08-03 20:33
VLAI?
Summary
avahi-daemon-check-dns.sh in the Debian avahi package through 0.8-4 is executed as root via /etc/network/if-up.d/avahi-daemon, and allows a local attacker to cause a denial of service or create arbitrary empty files via a symlink attack on files under /run/avahi-daemon. NOTE: this only affects the packaging for Debian GNU/Linux (used indirectly by SUSE), not the upstream Avahi product.
Severity ?
No CVSS data available.

CVE-2017-6519 (GCVE-0-2017-6519)
Vulnerability from cvelistv5 – Published: 2017-05-01 01:00 – Updated: 2025-12-03 21:57
VLAI?
Summary
avahi-daemon in Avahi through 0.6.32 and 0.7 inadvertently responds to IPv6 unicast queries with source addresses that are not on-link, which allows remote attackers to cause a denial of service (traffic amplification) and may cause information leakage by obtaining potentially sensitive information from the responding device via port-5353 UDP packets. NOTE: this may overlap CVE-2015-2809.
Severity ?
9.1 (Critical)

VAR-201504-0248
Vulnerability from variot - Updated: 2025-04-13 23:18The Multicast DNS (mDNS) responder in Synology DiskStation Manager (DSM) before 3.1 inadvertently responds to unicast queries with source addresses that are not link-local, which allows remote attackers to cause a denial of service (traffic amplification) or obtain potentially sensitive information via port-5353 UDP packets to the Avahi component. Multicast DNS implementations may respond to unicast queries that originate from sources outside of the local link network. Such responses may disclose information about network devices or be used in denial-of-service (DoS) amplification attacks. Multiple products are prone to an information-disclosure vulnerability. Attackers can exploit this issue to obtain sensitive information or crash the system, resulting in a denial-of-service condition. Other attacks are also possible. Synology DiskStation Manager (DSM) is an operating system developed by Synology for network storage servers (NAS). The operating system can manage data, documents, photos, music and other information

VAR-201504-0377
Vulnerability from variot - Updated: 2025-04-13 23:18The Multicast DNS (mDNS) responder in IBM Security Access Manager for Web 7.x before 7.0.0 FP12 and 8.x before 8.0.1 FP1 inadvertently responds to unicast queries with source addresses that are not link-local, which allows remote attackers to cause a denial of service (traffic amplification) or obtain potentially sensitive information via port-5353 UDP packets. Multicast DNS implementations may respond to unicast queries that originate from sources outside of the local link network. Such responses may disclose information about network devices or be used in denial-of-service (DoS) amplification attacks. Multiple products are prone to an information-disclosure vulnerability. Attackers can exploit this issue to obtain sensitive information or crash the system, resulting in a denial-of-service condition. Other attacks are also possible. IBM Security Access Manager (ISAM) for Web (formerly known as IBM Tivoli Access Manager for e-business) is a set of products used in user authentication, authorization and Web single sign-on solutions of IBM Corporation in the United States. It provides user access management and Web application protection function. The following versions are affected: ISAM for Web 7.0 with firmware 7.0.0.11 and earlier, and ISAM for Web 8.0 with firmware 8.0.0.1 through 8.0.0.5 and 8.0.1.0
