Sbc: sbc: heap out-of-bounds read via crafted sbc audio frame
A flaw was found in the sbc library (BlueZ SBC codec). An off-by-one error in the SBC frame decoder allows a crafted audio payload to trigger a one-byte heap out-of-bounds read. This could allow an adjacent attacker streaming Bluetooth audio to read a single …

Libarchive: libarchive: signed integer overflow in archive_write_zip_header
A signed integer overflow vulnerability was found in libarchive's ZIP writer. In the archive_write_zip_header function in archive_write_set_format_zip.c, when ZIP encryption is enabled and the entry file size is close to INT64_MAX, the addition of the encrypt…

Libsoup: heap out-of-bounds read in libsoup due to integer truncation
A heap out-of-bounds read flaw was found in libsoup. When parsing multipart HTTP messages, an integer type mismatch between the caller and soup_headers_parse() can cause the length parameter to be incorrectly truncated, leading to a heap buffer over-read. A r…

Libsoup: information disclosure in libsoup via soupauthmanager proxy credential leak on proxy switch
SoupAuthManager caches proxy authentication credentials without scoping them to the proxy authority (host:port). When the proxy configuration changes (e.g., via system settings or WPAD), cached Proxy-Authorization headers from the previous proxy are sent to t…

Ansible-core: argument injection in ansible-galaxy collection install via git clone (incomplete fix for cve-2026-11332)
A flaw was found in ansible-core. The _extract_collection_from_git() function in ansible-core's concrete_artifact_manager.py constructs git clone commands without a '--' (end-of-options) separator before user-supplied URLs when installing collections from git…

Libssh: libssh: authentication bypass via missing gssapi principal check
A flaw was found in libssh. On servers with GSSAPIKeyExchange enabled, the gssapi-keyex path does not verify whether the authenticated Kerberos principal is authorized for the requested local user, allowing authenticated clients to log in as arbitrary users.
-
Medium 4.3
Libssh: libssh: use-after-free via data callbacks on closed channels
A flaw was found in libssh. If data packets are processed after a channel is closed, channel data callbacks can be invoked after the associated data has already been freed, leading to crashes or possible use-after-free conditions.
-
Low 3.1
Libssh: libssh: denial of service via automatic certificate authentication loop
A flaw was found in libssh. Logic errors in automatic certificate-based public key authentication can cause libssh clients to loop indefinitely when configured certificates are missing or repeatedly rejected by a server, leading to denial of service.
-
Medium 5.3
Libssh: libssh: denial of service via sftp responses with unknown request ids
A flaw was found in libssh. A malicious SFTP server can send responses for unknown request IDs that libssh clients keep queued indefinitely, causing unbounded memory growth and client-side denial of service.
-
Medium 5.9
Libssh: libssh: integrity downgrade via openssl aes-gcm tag verification
A flaw was found in libssh. Incorrect AES-GCM finalization checks in builds using the OpenSSL backend can effectively remove integrity protection, allowing an in-path attacker to modify plaintext on the wire without detection.
-
Low 3.9
Libssh: libssh: information disclosure via proxycommand %r username expansion
A flaw was found in libssh. A malicious username expanded through %r in ProxyCommand handling can inject shell metacharacters, exposing environment variables and causing unintended shell behavior.

Medium 6.5
Libssh: libssh: denial of service via oversized sftp read length
A flaw was found in libssh. A remote authenticated client can issue SSH_FXP_READ requests with an arbitrarily large length, causing a libssh SFTP server to allocate excessive memory and potentially exhaust it through repeated requests.
-
Medium 5.3
Libssh: libssh: denial of service via unchecked proxycommand fork() failure
A flaw was found in libssh. When ProxyCommand is used, an unchecked fork() failure can be stored as process ID -1; during cleanup, signals may then be sent across the caller's accessible process tree, leading to local denial of service.
-
Medium 6.5
Libssh: libssh: denial of service via zero advertised channel packet size
A flaw was found in libssh. A remote authenticated peer can advertise a zero maximum packet size in SSH_MSG_CHANNEL_OPEN, causing later channel writes to loop indefinitely and consume CPU, leading to denial of service.
-
Low 3.7
Libssh: libssh: information disclosure via short gssapi curve25519 public key
A flaw was found in libssh. During server-side GSSAPI key exchange, a client-supplied Curve25519 public key shorter than the expected length is copied without proper length validation, leading to an out-of-bounds heap read. This could allow a remote unauthent…

Medium 6.7
Libssh: libssh: stack buffer overflow in sftp server longname construction
A flaw was found in libssh. During SFTP server directory listing, the longname field is constructed with unsafe concatenation into a fixed-size stack buffer. When a client causes the server to list attacker-controlled filenames, sufficiently long names can ov…
