Description

This security bulletin contains information about 1 vulnerability.


1) Information disclosure (CVE-ID: CVE-2019-18679)

CWE-ID: CWE-200 - Exposure of sensitive information to an unauthorized actor

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


The vulnerability allows a remote attacker to gain access to potentially sensitive information.

The vulnerability exists due to incorrect data management when processing HTTP Digest Authentication. Nonce tokens contain the raw byte value of a pointer which sits within heap memory allocation. This allows a remote attacker to gain knowledge of memory allocations and bypass ASLR protection and help in exploitation of other vulnerabilities.
