Name of the Vulnerable Software and Affected Versions
libsoup (affected versions not specified)
Description
An unsigned to signed conversion error exists in the
soup body input stream read chunked() function. A remote attacker can exploit this by sending a malicious HTTP request when libsoup is used behind a non-libsoup proxy server or as a proxy in front of a non-libsoup backend server. This can lead to HTTP request smuggling, allowing the attacker to bypass security controls, poison web caches, or gain unauthorized access.Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
