This flaw can be triggered when a libsoup client receives a 401 (Unauthorized) HTTP response containing a specifically crafted domain parameter within the WWW-Authenticate header. Processing this malformed header can lead to a crash of the client application using libsoup. An attacker could exploit this by setting up a malicious HTTP server. If a user's application using the vulnerable libsoup library connects to this malicious server, it could result in a denial-of-service. Successful exploitation requires tricking a user's client application into connecting to the attacker's malicious server. CVE-2025-4476 SUSE Linux Micro 6.0:libsoup-3_0-0-3.4.2-8.1 important To install this SUSE Security Update use the SUSE recommended installation methods like YaST online_update or "zypper patch". https://www.suse.com/support/update/announcement/2025/suse-su-202520453-1/ https://www.suse.com/security/cve/CVE-2025-4476.html CVE-2025-4476 https://bugzilla.suse.com/1243422 SUSE Bug 1243422 A flaw was found in the cookie parsing logic of the libsoup HTTP library, used in GNOME applications and other software. The vulnerability arises when processing the expiration date of cookies, where a specially crafted value can trigger an integer overflow. This may result in undefined behavior, allowing an attacker to bypass cookie expiration logic, causing persistent or unintended cookie behavior. The issue stems from improper validation of large integer inputs during date arithmetic operations within the cookie parsing routines. CVE-2025-4945 SUSE Linux Micro 6.0:libsoup-3_0-0-3.4.2-8.1 important To install this SUSE Security Update use the SUSE recommended installation methods like YaST online_update or "zypper patch". https://www.suse.com/support/update/announcement/2025/suse-su-202520453-1/ https://www.suse.com/security/cve/CVE-2025-4945.html CVE-2025-4945 https://bugzilla.suse.com/1243314 SUSE Bug 1243314 A flaw was found in the soup_multipart_new_from_message() function of the libsoup HTTP library, which is commonly used by GNOME and other applications to handle web communications. The issue occurs when the library processes specially crafted multipart messages. Due to improper validation, an internal calculation can go wrong, leading to an integer underflow. This can cause the program to access invalid memory and crash. As a result, any application or server using libsoup could be forced to exit unexpectedly, creating a denial-of-service (DoS) risk. CVE-2025-4948 SUSE Linux Micro 6.0:libsoup-3_0-0-3.4.2-8.1 important To install this SUSE Security Update use the SUSE recommended installation methods like YaST online_update or "zypper patch". https://www.suse.com/support/update/announcement/2025/suse-su-202520453-1/ https://www.suse.com/security/cve/CVE-2025-4948.html CVE-2025-4948 https://bugzilla.suse.com/1243332 SUSE Bug 1243332 A vulnerability was found in the libsoup package. This flaw stems from its failure to correctly verify the termination of multipart HTTP messages. This can allow a remote attacker to send a specially crafted multipart HTTP body, causing the libsoup-consuming server to read beyond its allocated memory boundaries (out-of-bounds read). CVE-2025-4969 SUSE Linux Micro 6.0:libsoup-3_0-0-3.4.2-8.1 important To install this SUSE Security Update use the SUSE recommended installation methods like YaST online_update or "zypper patch". https://www.suse.com/support/update/announcement/2025/suse-su-202520453-1/ https://www.suse.com/security/cve/CVE-2025-4969.html CVE-2025-4969 https://bugzilla.suse.com/1243423 SUSE Bug 1243423
