The vulnerability allows a remote user to gain access to potentially sensitive information.
The vulnerability exists due to a boundary condition within the sftp_handle() function. A remote user can trigger an out-of-bounds read error and read contents of memory on the system.
2) Uncaught Exception (CVE-ID: CVE-2025-59465)
CWE-ID: CWE-248 - Uncaught Exception
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:Green
The vulnerability allows a remote attacker to cause a denial of service.
The vulnerability exists due to improper error handling in the HTTP/2 server when receiving a malformed HEADERS frame with oversized invalid HPACK data. A remote attacker can send a specially crafted HTTP/2 HEADERS frame to cause a denial of service.
This primarily affects applications that do not attach explicit error handlers to secure sockets.
3) Resource exhaustion (CVE-ID: CVE-2025-61729)
CWE-ID: CWE-400 - Resource exhaustion
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:Green
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to application does not properly control consumption of internal resources within the HostnameError.Error() function in crypto/x509 when printing error string for host certificate validation. A remote attacker can supply a specially crafted certificate to the application and trigger resource exhaustion, leading to a denial of service condition.
