Description
This security bulletin contains information about 8 vulnerabilities.
1) Buffer Over-read (CVE-ID: CVE-2025-32050)
CWE-ID: CWE-126 - Buffer over-read
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Green
The vulnerability allows a remote attacker to gain access to sensitive information.
The vulnerability exists due to a boundary error within the append_param_quoted() function when handling server HTTP response. A remote attacker can trick the victim into visiting a specially crafted website and read parts of the heap memory.
2) Buffer Over-read (CVE-ID: CVE-2025-32052)
CWE-ID: CWE-126 - Buffer over-read
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Green
The vulnerability allows a remote attacker to gain access to sensitive information.
The vulnerability exists due to a boundary error within the sniff_unknown() function when handling server HTTP response. A remote attacker can trick the victim into visiting a specially crafted website and read parts of the heap memory.
3) Buffer Over-read (CVE-ID: CVE-2025-32053)
CWE-ID: CWE-126 - Buffer over-read
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Green
The vulnerability allows a remote attacker to gain access to sensitive information.
The vulnerability exists due to a boundary error within the sniff_feed_or_html() and skip_insignificant_space() functions when parsing server HTTP response. A remote attacker can trick the victim into visiting a specially crafted website and read parts of the heap memory.
4) Out-of-bounds read (CVE-ID: CVE-2025-32906)
CWE-ID: CWE-125 - Out-of-bounds read
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Green
The vulnerability allows a remote attacker to gain access to potentially sensitive information.
The vulnerability exists due to a boundary condition in soup_headers_parse_request() function. A remote attacker can trick the victim into visiting a specially crafted website, trigger an out-of-bounds read error and read contents of memory on the system.
5) Use-after-free (CVE-ID: CVE-2025-32911)
CWE-ID: CWE-416 - Use After Free
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Amber
The vulnerability allows a remote attacker to compromise vulnerable system.
The vulnerability exists due to a use-after-free error within the soup_message_headers_get_content_disposition(). A remote attacker can trick the victim into visiting a specially crafted website and execute arbitrary code on the target system.
Successful exploitation of the vulnerability may allow an attacker to compromise vulnerable system.
6) NULL pointer dereference (CVE-ID: CVE-2025-32913)
CWE-ID: CWE-476 - NULL Pointer Dereference
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Amber
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a NULL pointer dereference error in the soup_message_headers_get_content_disposition() function. A remote attacker can pass specially crafted data to the application and perform a denial of service (DoS) attack.
7) Memory leak (CVE-ID: CVE-2025-46420)
CWE-ID: CWE-401 - Missing release of memory after effective lifetime
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:U/U:Clear
The vulnerability allows a remote attacker to perform DoS attack on the target system.
The vulnerability exists due memory leak within the soup_header_parse_quality_list() function. A remote attacker can force the application to leak memory and perform denial of service attack.
8) Information disclosure (CVE-ID: CVE-2025-46421)
CWE-ID: CWE-200 - Exposure of sensitive information to an unauthorized actor
CVSSv4: CVSS:4.0/AV:N/AC:H/AT:N/PR:N/UI:A/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear
The vulnerability allows a remote attacker to gain access to potentially sensitive information.
The vulnerability exists due to libsoup includes authorization headers into requests when handling HTTP redirects. A remote attacker can gain access to credentials intended for a different website.
