UBUNTU-CVE-2026-3632

A flaw was found in libsoup, a library used by applications to send network requests. This vulnerability occurs because libsoup does not properly validate hostnames, allowing special characters to be injected into HTTP headers. A remote attacker could exploit this to perform HTTP smuggling, where...

UBUNTU-CVE-2026-3634

A flaw was found in libsoup. An attacker controlling the value used to set the Content-Type header can inject a Carriage Return Line Feed CRLF sequence due to improper input sanitization in the soupmessageheaderssetcontenttype function. This vulnerability allows for the injection of arbitrary...
