glibc: glibc: Invalid DNS hostname returned via gethostbyaddr functions
A flaw was found in the GNU C library glibc. When applications use the gethostbyaddr or gethostbyaddrr functions with a nsswitch.conf configuration that specifies glibc's DNS backend, the library may return an invalid DNS hostname. This violates the DNS specification and could lead to application...
CVE-2026-3039
BIND servers that are configured to use TKEY-based authentication via GSS-API tokens are vulnerable to excessive memory consumption when receiving and processing maliciously-constructed packets. Typically these servers will be found in Active Directory integrated DNS deployments and/or...
Astra Linux – Vulnerability in glibc
NSCD: Stack-based buffer overflow in netgroup cache If the fixed-size cache of the Name Service Cache Daemon nscd is exhausted due to client requests, then a subsequent client request for netgroup data may lead to a stack-based buffer overflow. This flaw was introduced in glibc 2.15 when the cach...
Astra Linux – Vulnerability in glibc
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 nssgethostbyname2r and nssgetcanonnamer hooks without...
