CVE-2025-61724: CWE-407: Inefficient Algorithmic Complexity in Go standard library net/textproto
CVE-2025-61724 is a medium severity vulnerability in the Go standard library's net/textproto package. The Reader.ReadResponse function uses repeated string concatenation to build response strings from multiple lines, causing inefficient algorithmic complexity. This inefficiency can lead to excessive CPU consumption and denial of service due to resource exhaustion. There is no impact on confidentiality or integrity. No patch or official fix has been confirmed yet.
AI Analysis
Technical Summary
The vulnerability CVE-2025-61724 affects the Go standard library net/textproto package, specifically the Reader.ReadResponse function. The function's implementation uses repeated string concatenation when processing multi-line responses, which results in inefficient algorithmic complexity. This inefficiency can cause excessive CPU usage when handling responses with many lines, leading to a denial of service condition through resource exhaustion. The vulnerability does not affect confidentiality or integrity of data. No official patch or fix has been announced or confirmed at this time.
Potential Impact
The vulnerability can cause denial of service by consuming excessive CPU resources when processing large multi-line responses in the net/textproto Reader.ReadResponse function. There is no confidentiality or integrity impact reported.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, consider limiting exposure to untrusted inputs that might trigger this behavior or applying application-level rate limiting to mitigate potential denial of service.
