CVE-2018-25396 2 Heatmiser, Redhat 2 Heatmiser Wifi Thermostat, Thermostat 2026-07-28 7.5 High
Heatmiser Wifi Thermostat 1.7 contains a credential disclosure vulnerability that allows unauthenticated attackers to retrieve administrative credentials by accessing the networkSetup.htm page. Attackers can request the networkSetup.htm endpoint and extract plaintext username and password values from HTML form fields to gain administrative access to the thermostat.
CVE-2026-14476 2 Redhat, Sssd 5 Enterprise Linux, Enterprise Linux Eus, Openshift and 2 more 2026-07-28 8 High
A path traversal flaw was found in SSSD's AD GPO provider. The ad_gpo_extract_smb_components() function does not sanitize .. sequences in the gPCFileSysPath LDAP attribute, allowing an attacker with AD GPO management access to write files outside the GPO cache directory as root. On default RHEL configurations with SELinux enforcing, this can be used to inject Kerberos configuration leading to authentication bypass.
CVE-2026-14474 1 Redhat 3 Enterprise Linux, Enterprise Linux Eus, Openshift 2026-07-28 8.8 High
A flaw was found in SSSD's LDAP sudo provider. When the ldap_sudo_search_base option is not explicitly configured, SSSD searches the entire LDAP directory tree for sudoRole objects. An authenticated attacker with write access to any subtree can inject a sudoRole object granting root-level sudo privileges on all SSSD-enrolled hosts.
CVE-2026-66035 2 Libssh2, Redhat 2 Libssh2, Hummingbird 2026-07-28 7.5 High
libssh2 through 1.11.1, fixed in commit 42e33d8, contains a pre-authentication heap buffer overflow vulnerability that allows a malicious SSH server to corrupt heap metadata in any connecting client by sending a packet with a packet_length smaller than the cipher's block size during Encrypt-then-MAC cipher negotiation. In the fullpacket() function in src/transport.c, the ETM path allocates a buffer of packet_length bytes but copies blocksize minus one bytes via memcpy, causing an overflow that on 32-bit glibc writes attacker-controlled bytes into an adjacent chunk's SIZE field, enabling tcache bin confusion, overlapping live objects, and function pointer overwrite during the session handshake before authentication.
CVE-2026-66034 2 Libssh2, Redhat 2 Libssh2, Hummingbird 2026-07-28 7.5 High
libssh2 through 1.11.1, fixed in commit a13bb6c, contains a missing bounds check vulnerability that allows a malicious SSH server to trigger an arbitrary-length heap out-of-bounds read and a free of an uninitialized pointer via the publickey subsystem. In libssh2_publickey_list_fetch(), the version 1 response parser reads a server-controlled comment_len value and advances the parse pointer without verifying sufficient bytes remain in the buffer, causing the out-of-bounds read to leak heap pointers from adjacent allocations defeating ASLR, followed by heap allocator state corruption when the error cleanup path frees an uninitialized pointer from a non-zeroed realloc() region.
CVE-2026-66033 2 Libssh2, Redhat 2 Libssh2, Hummingbird 2026-07-28 7.5 High
libssh2 through 1.11.1, fixed in commit a2ed82d, contains a pre-authentication integer underflow vulnerability in the ssh2_cipher_crypt() function in src/openssl.c that allows a malicious SSH server to crash any connecting client by negotiating AES-GCM ciphers during handshake. Attackers can exploit the underflow in the expression computing blocksize minus aadlen minus authentication tag length to trigger an out-of-bounds read and a memcpy call with a near-SIZE_MAX length argument, causing immediate process crash before any authentication occurs.
CVE-2026-66032 2 Libssh2, Redhat 2 Libssh2, Hummingbird 2026-07-28 8.8 High
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.
CVE-2026-15370 2 Libssh, Redhat 4 Libssh, Enterprise Linux, Hardened Images and 1 more 2026-07-27 6.7 Medium
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 overflow that stack buffer and may lead to crashes or possible code execution on the server.
CVE-2026-59842 2 Libssh, Redhat 4 Libssh, Enterprise Linux, Hardened Images and 1 more 2026-07-27 3.7 Low
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 unauthenticated attacker to disclose small amounts of server memory.
CVE-2026-59843 2 Libssh, Redhat 4 Libssh, Enterprise Linux, Hardened Images and 1 more 2026-07-27 6.5 Medium
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.
CVE-2026-59845 2 Libssh, Redhat 4 Libssh, Enterprise Linux, Hardened Images and 1 more 2026-07-27 5.3 Medium
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.
CVE-2026-59844 2 Libssh, Redhat 4 Libssh, Enterprise Linux, Hardened Images and 1 more 2026-07-27 6.5 Medium
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.
CVE-2026-59847 2 Libssh, Redhat 4 Libssh, Enterprise Linux, Hardened Images and 1 more 2026-07-27 5.9 Medium
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.
CVE-2026-59849 2 Libssh, Redhat 4 Libssh, Enterprise Linux, Hardened Images and 1 more 2026-07-27 3.1 Low
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.
CVE-2026-59850 2 Libssh, Redhat 4 Libssh, Enterprise Linux, Hardened Images and 1 more 2026-07-27 4.3 Medium
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.
CVE-2026-59851 2 Libssh, Redhat 4 Libssh, Enterprise Linux, Hardened Images and 1 more 2026-07-27 8.8 High
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.
CVE-2026-12547 2 Libsoup, Redhat 2 Libsoup, Enterprise Linux 2026-07-27 3.4 Low
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 the new proxy, leaking credentials.
CVE-2026-12548 2 Libsoup, Redhat 2 Libsoup, Enterprise Linux 2026-07-27 4.2 Medium
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 remote attacker could use this flaw to crash an application using libsoup or potentially disclose heap memory contents.
CVE-2026-16517 2 Libarchive, Redhat 6 Libarchive, Enterprise Linux, Hardened Images and 3 more 2026-07-27 2.9 Low
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 encryption overhead to the entry size overflows int64_t, resulting in undefined behavior. This could lead to incorrect Zip64 extension decisions or potential memory corruption.
CVE-2026-16473 2 Redhat, Sbc 2 Enterprise Linux, Sbc 2026-07-27 4.3 Medium
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 byte of adjacent heap memory.
