CVE-2026-0719

CVSS v2.0

9.0

High

VectorAV:N/AC:L/Au:N/C:P/I:P/A:C
Name of the Vulnerable Software and Affected Versions libsoup (affected versions not specified)
Description A flaw exists in the NTLM authentication handling of the libsoup HTTP library. An improper use of signed integers during a size calculation when processing long passwords can lead to an integer overflow. This results in incorrect memory allocation on the stack and subsequent unsafe memory copying. This can cause applications using libsoup to crash, leading to a denial-of-service condition. A local attacker can exploit a stack-based buffer overflow in the md4sum() function when NTLM authentication is enabled, potentially allowing arbitrary code execution with the privileges of the affected application.
Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
