CVE-2012-6063 1 Libssh 1 Libssh 2026-06-16 7.5 HIGH N/A
Double free vulnerability in the sftp_mkdir function in sftp.c in libssh before 0.5.3 allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via unspecified vectors, a different vector than CVE-2012-4559.
CVE-2012-4562 1 Libssh 1 Libssh 2026-06-16 7.5 HIGH N/A
Multiple integer overflows in libssh before 0.5.3 allow remote attackers to cause a denial of service (infinite loop or crash) and possibly execute arbitrary code via unspecified vectors, which triggers a buffer overflow, infinite loop, or possibly some other unspecified vulnerabilities.
CVE-2012-4561 1 Libssh 1 Libssh 2026-06-16 5.0 MEDIUM N/A
The (1) publickey_make_dss, (2) publickey_make_rsa, (3) signature_from_string, (4) ssh_do_sign, and (5) ssh_sign_session_id functions in keys.c in libssh before 0.5.3 free "an invalid pointer on an error path," which might allow remote attackers to cause a denial of service (crash) via unspecified vectors.
CVE-2012-4560 1 Libssh 1 Libssh 2026-06-16 7.5 HIGH N/A
Multiple buffer overflows in libssh before 0.5.3 allow remote attackers to cause a denial of service (crash) or possibly execute arbitrary code via unspecified vectors.
CVE-2012-4559 1 Libssh 1 Libssh 2026-06-16 6.8 MEDIUM N/A
Multiple double free vulnerabilities in the (1) agent_sign_data function in agent.c, (2) channel_request function in channels.c, (3) ssh_userauth_pubkey function in auth.c, (4) sftp_parse_attr_3 function in sftp.c, and (5) try_publickey_from_file function in keyfiles.c in libssh before 0.5.3 allow remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via unspecified vectors.
