Vulnerability Title
Libsoup: signed to unsigned conversion error leading to stack-based buffer overflow in libsoup ntlm authentication
Source: NVD (National Vulnerability Database)
Vulnerability Description
A flaw was identified in the NTLM authentication handling of the libsoup HTTP library, used by GNOME and other applications for network communication. When processing extremely long passwords, an internal size calculation can overflow due to improper use of signed integers. This results in incorrect memory allocation on the stack, followed by unsafe memory copying. As a result, applications using libsoup may crash unexpectedly, creating a denial-of-service risk.
