Description

This security bulletin contains information about 2 vulnerabilities.


1) NULL pointer dereference (CVE-ID: N/A)

CWE-ID: CWE-476 - NULL Pointer Dereference

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear


The vulnerability allows a remote user to cause a denial of service.

The vulnerability exists due to null pointer dereference in JNI-based XXHash implementations when processing a null byte array reference with a zero-length range. A remote user can pass a null array reference to native XXHash methods to cause a denial of service.

This affects the native XXHash hash and streaming update APIs, while Java-based XXHash implementations are not affected.


2) Out-of-bounds read (CVE-ID: N/A)

CWE-ID: CWE-125 - Out-of-bounds read

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:L/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear


The vulnerability allows a remote user to disclose sensitive information and cause a denial of service.

The vulnerability exists due to out-of-bounds read in streaming JNI-based XXHash implementations when processing an oversized length for a byte array. A remote user can pass a crafted length value to native XXHash update methods to disclose sensitive information and cause a denial of service.

The issue affects the streaming native XXHash update APIs. The non-streaming oversized-length hash case was already rejected in Java.
