Astra Linux – Vulnerability in glibc

Calling getnetbyaddr or getnetbyaddrr with a configured nsswitch.conf that specifies the library’s DNS backend can lead to a situation where a zero-valued network is queried during operations in the GNU C Library versions 2.0 to 2.42. This could result in the leakage of stack contents to the...

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...
