Kerberos Protocol Analyzer DoS

The vulnerability of the Kerberos protocol analyzer, a tool for analyzing network traffic in computers, is related to reading beyond the buffer boundaries in memory. Exploiting this vulnerability can allow an attacker to cause a service failure...

CVE-2026-60109

Zeek before 8.0.9 contains a null pointer dereference vulnerability in its Kerberos protocol analyzer that allows unauthenticated remote attackers to crash the sensor by sending a crafted KRBERROR message with error-code 25 KDCERRPREAUTHREQUIRED containing a PA-DATA element with padata-type 2, 3,...

FreeBSD : zeek -- potential DoS vulnerabilities (d47e608f-2e2a-4366-ad17-ce2480bf912d)

The version of FreeBSD installed on the remote host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the d47e608f-2e2a-4366-ad17-ce2480bf912d advisory. Tim Wojtulewicz of Corelight reports: The NVT, Rlogin, and RSH analyzers have received fixes to avoid...

zeek -- potential DoS vulnerabilities

Tim Wojtulewicz of Corelight reports: The NVT, Rlogin, and RSH analyzers have received fixes to avoid unbounded state growth. Due to the fact that these packets can be received from remote hosts, these are considered DoS risks. A specially crafted WebSocket payload can cause the Spicy WebSocket...

zeek -- information leak vulnerability

Tim Wojtulewicz of Corelight reports: The KRB analyzer can leak information about hosts in analyzed traffic via external DNS lookups...

bro -- Unsafe integer conversions can cause unintentional code paths to be executed

Jon Siwek of Corelight reports: The following Denial of Service vulnerabilities are addressed: Integer type mismatches in BinPAC-generated parser code and Bro analyzer code may allow for crafted packet data to cause unintentional code paths in the analysis logic to be taken due to unsafe integer...
