Astra Linux – Vulnerability in libuv1

Node.js versions prior to 16.4.1, 14.17.2, and 12.22.2 are vulnerable to an out-of-bounds read when the uvidnatoascii function is used to convert strings to ASCII. The pointer p is read and incremented without checking whether it lies beyond pe, where pe holds a pointer to the end of the buffer...

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...

Astra Linux – Vulnerability in libuv1

libuv is a multi-platform support library that focuses on asynchronous I/O operations. The uvgetaddrinfo function in src/unix/getaddrinfo.c and its Windows counterpart src/win/getaddrinfo.c truncates hostnames to 256 characters before calling getaddrinfo. This behavior can be exploited to generat...

Astra Linux – Vulnerability in glibc

A flaw has been identified in glibc. In a rare situation, the gaihinet function may use memory that has already been freed, leading to an application crash. This issue is only exploitable when the getaddrinfo function is called and the hosts database in /etc/nsswitch.conf is configured with...
