Vulnerability from cvelistv5

CWE
  • CWE-276 - Incorrect Default Permissions
Summary
A vulnerability was found in Unbound due to incorrect default permissions, allowing any process outside the unbound group to modify the unbound runtime configuration. If a process can connect over localhost to port 8953, it can alter the configuration of unbound.service. This flaw allows an unprivileged attacker to manipulate a running instance, potentially altering forwarders, allowing them to track all queries forwarded by the local resolver, and, in some cases, disrupting resolving altogether.

CVE-2023-4806 (GCVE-0-2023-4806)
Vulnerability from cvelistv5
Published
2023-09-18 16:33
Modified
2025-11-20 17:55
CWE
Summary
A flaw has been identified in glibc. In an extremely rare situation, the getaddrinfo function may access memory that has been freed, resulting in an application crash. This issue is only exploitable when a NSS module implements only the _nss_*_gethostbyname2_r and _nss_*_getcanonname_r hooks without implementing the _nss_*_gethostbyname3_r hook. The resolved name should return a large number of IPv6 and IPv4, and the call to the getaddrinfo function should have the AF_INET6 address family with AI_CANONNAME, AI_ALL and AI_V4MAPPED as flags.

CVE-2023-4527 (GCVE-0-2023-4527)
Vulnerability from cvelistv5
Published
2023-09-18 16:32
Modified
2025-11-20 18:27
CWE
  • CWE-121 - Stack-based Buffer Overflow
Summary
A flaw was found in glibc. When the getaddrinfo function is called with the AF_UNSPEC address family and the system is configured with no-aaaa mode via /etc/resolv.conf, a DNS response via TCP larger than 2048 bytes can potentially disclose stack contents through the function returned address data, and may cause a crash.
