CVE-2017-9108 Memory corruption in n/a

What is CVE-2017-9108?

CVE-2017-9108 is a high-severity memory corruption vulnerability in Fedoraproject Fedora, published on 18 Jun 2020. An attacker can exploit it over the internet without logging in, with no action from the victim.

Official description

An issue was discovered in adns before 1.5.2. adnshost mishandles a missing final newline on a stdin read. It is wrong to increment used as well as setting r, since used is incremented according to r, later. Rather one should be doing what read() would have done. Without this fix, adnshost may read and process one byte beyond the buffer, perhaps crashing or perhaps somehow leaking the value of that byte.

Weakness: CWE-119
