libsoup2.4

libsoup3

A vulnerability in libsoup2.4's soup_filter_input_stream_read_until() function causes an unsigned integer underflow, leading to a heap buffer over-read when parsing multipart HTTP responses. This flaw can be triggered by a malicious HTTP server sending crafted multipart responses, potentially causing client crashes or disclosure of sensitive heap memory. The issue affects multiple specific versions of libsoup2.4. The CVSS score is 6.5, indicating a medium severity level.

CVE-2026-66337 is a vulnerability in libsoup2.4 where an unsigned integer underflow occurs in the soup_filter_input_stream_read_until() function. This underflow leads to a heap buffer over-read during the parsing of multipart HTTP responses. Exploitation requires a malicious HTTP server to send specially crafted multipart responses, which may cause client crashes or leak sensitive heap memory. The vulnerability affects numerous explicitly listed versions of libsoup2.4. No patch or remediation information is provided in the input data.

A flaw was found in libsoup. An unsigned integer underflow in the soup_filter_input_stream_read_until() function causes a heap buffer over-read when parsing multipart HTTP responses. A malicious HTTP server can exploit this by sending a crafted multipart response, potentially causing the client application to crash or disclose sensitive heap memory.

This vulnerability arises from an unsigned integer underflow in the libsoup library's soup_filter_input_stream_read_until() function. When parsing multipart HTTP responses, this flaw causes a heap buffer over-read, which can be triggered by a malicious HTTP server sending a specially crafted multipart response. The impact includes potential client application crashes or leakage of sensitive heap memory. The vulnerability affects Red Hat Enterprise Linux 10, but no specific affected versions or patch information is provided in the available data. The CVSS v3.1 base score is 6.5, indicating medium severity with network attack vector, low attack complexity, no privileges required, no user interaction, unchanged scope, limited confidentiality impact, no integrity impact, and low availability impact.
