CVE-2026-5358
The CVE affects the GNU C Library (glibc) up to version 2.43, where the obsolete nis_local_principal function can overflow a buffer in the data section. This may allow an attacker to spoof a crafted UDP response and overwrite neighboring static data in the requesting application. NIS support is d...

Name of the Vulnerable Software and Affected Versions glibc versions 2.7 through 2.43 Description Calling the scanf family of functions using a %mc malloc'd character match with a format width specifier that has an explicit width greater than 1024 can lead to a one byte heap buffer overflow...
CVE-2026-5450: Heap-based Buffer Overflow
Calling the scanf family of functions with a %mc malloc'd character match in the GNU C Library version 2.7 to version 2.43 with a format width specifier with an explicit width greater than 1024 could result in a one byte heap buffer overflow...

glibc: glibc: Information disclosure via zero-valued network query
A flaw was found in glibc, the GNU C Library. When an application calls the getnetbyaddr or getnetbyaddrr functions to resolve a network address, and the system's nsswitch.conf file is configured to use a DNS Domain Name System backend for network lookups, a query for a zero-valued network can le...
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...
glibc: glibc: Incorrect DNS response parsing via crafted DNS server response
A flaw was found in glibc the GNU C Library. When an application uses the gethostbyaddr or gethostbyaddrr functions with a nsswitch.conf configuration that specifies glibc's DNS backend, a remote attacker can send a specially crafted DNS Domain Name System response. This crafted response can caus...
