FastNetMon: NetFlow v9 unbounded strlen() on interface-description field causes remote out-of-bounds read

Özet

Türkçe özeti henüz hazır değil; şimdilik kaynağın kendi açıklamasını gösteriyoruz.

FastNetMon is a high-performance DDoS detector and sensor. In version 1.2.9 and earlier, the NetFlow v9 collector calls  strlen()  on an attacker-controlled interface-description field without bounding the scan to the field’s declared length. Although fields longer than 128 bytes are excluded from this operation, an accepted field without a null terminator can cause reads beyond the field and packet buffer. An unauthenticated remote attacker who can send crafted UDP packets to the collector can trigger an out-of-bounds read and potentially crash the process, causing denial of service. No fixed release is available as of this review.
