CVE-2016-10708
HighSummary
W OpenSSH przed wersją 7.4 występuje podatność, która pozwala zdalnym atakującym na spowodowanie odmowy usługi poprzez dereferencję wskaźnika NULL i awarię demona, wykorzystując nieprawidłową sekwencję wiadomości NEWKEYS.
Risk Assessment
Atakujący mogą wykorzystać tę podatność do zakłócenia działania serwera SSH, co może prowadzić do przerwy w dostępności usług dla użytkowników.
Recommendation
Zaleca się aktualizację OpenSSH do wersji 7.4 lub nowszej, aby usunąć tę podatność i zabezpieczyć serwer przed potencjalnymi atakami.

Original NVD description (English source)
sshd in OpenSSH before 7.4 allows remote attackers to cause a denial of service (NULL pointer dereference and daemon crash) via an out-of-sequence NEWKEYS message, as demonstrated by Honggfuzz, related to kex.c and packet.c.
