Vulnerability from variot - Updated: 2023-12-18 12:38The 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

VAR-201504-0248
Vulnerability from variot - Updated: 2023-12-18 12:38The 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

FKIE_CVE-2021-3468
Vulnerability from fkie_nvd - Published: 2021-06-02 16:15 - Updated: 2024-11-21 06:21
Severity ?
Summary
A flaw was found in avahi in versions 0.6 up to 0.8. The event used to signal the termination of the client connection on the avahi Unix socket is not correctly handled in the client_work function, allowing a local attacker to trigger an infinite loop. The highest threat from this vulnerability is to the availability of the avahi service, which becomes unresponsive after this flaw is triggered.

Severity ?
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.

FKIE_CVE-2017-6519
Vulnerability from fkie_nvd - Published: 2017-05-01 01:59 - Updated: 2025-12-03 22:15
Severity ?
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-2021-3468 (GCVE-0-2021-3468)
Vulnerability from cvelistv5 – Published: 2021-06-02 15:09 – Updated: 2025-02-13 16:28

Summary
A flaw was found in avahi in versions 0.6 up to 0.8. The event used to signal the termination of the client connection on the avahi Unix socket is not correctly handled in the client_work function, allowing a local attacker to trigger an infinite loop. The highest threat from this vulnerability is to the availability of the avahi service, which becomes unresponsive after this flaw is triggered.
Severity ?
No CVSS data available.

CVE-2021-26720 (GCVE-0-2021-26720)
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.

Summary
A flaw was found in avahi in versions 0.6 up to 0.8. The event used to signal the termination of the client connection on the avahi Unix socket is not correctly handled in the client_work function, allowing a local attacker to trigger an infinite loop. The highest threat from this vulnerability is to the availability of the avahi service, which becomes unresponsive after this flaw is triggered.

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.
