Title

libssh2 Double-Free Heap Corruption via sftp_open()

Summary

libssh2 through 1.11.1, fixed in commit 5e47761, contains a double-free vulnerability in the sftp_open() function in src/sftp.c that allows a malicious SSH server to corrupt the heap of any authenticated client opening an SFTP session. When a server responds to SSH_FXP_OPEN with SSH_FXP_STATUS containing FX_OK, the response data buffer is freed, and if a subsequent sftp_packet_require() call returns a specific error such as LIBSSH2_ERROR_CHANNEL_PACKET_EXCEEDED, the same pointer is freed a second time, enabling tcache dup conditions on glibc systems that allow overlapping allocations and function pointer overwrites.

Red Hat Security Advisory: Red Hat Hardened Images RPMs Security Update

Severity

Important

Scope

4 vulnerabilities in this advisory, including CVE-2026-66032.

CVE-2026-66032

A flaw was found in libssh2. A malicious SSH (Secure Shell) server can exploit a double-free vulnerability in the sftp_open() function. This flaw allows the server to corrupt the heap memory of an authenticated client when it opens an SFTP (SSH File Transfer Protocol) session. This heap corruption can lead to arbitrary code execution on the client system, giving the attacker control over the affected system.

When a server responds to SSH_FXP_OPEN with SSH_FXP_STATUS containing FX_OK, the response data buffer is freed, and if a subsequent sftp_packet_require() call returns a specific error such as LIBSSH2_ERROR_CHANNEL_PACKET_EXCEEDED, the same pointer is freed a second time, enabling tcache dup conditions on glibc systems that allow overlapping allocations and function pointer overwrites.",

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base model, served locally by ML-Gateway. They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
