DescriptionCVE.org

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.

AnalysisAI

Libsoup's NTLM authentication handler crashes when processing exceptionally long passwords due to a signed integer overflow in memory allocation calculations, affecting GNOME and applications relying on this library for network operations. An unauthenticated remote attacker can trigger a denial-of-service condition by sending specially crafted authentication requests. No patch is currently available.

Technical ContextAI

Classified as CWE-121 (Stack-based Buffer Overflow). 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.

Affected ProductsAI

A flaw was identified in the NTLM authentication handling of the libsoup HTTP library, used by GNOME and other applications for network communication.

RemediationAI

Monitor vendor advisories for a patch. Restrict network access to the affected service where possible.
