CVE-2026-3832: Gnutls: gnutls: security bypass allows acceptance of revoked server certificates via crafted ocsp response

A flaw was found in gnutls. A remote attacker could exploit this vulnerability by presenting a specially crafted Online Certificate Status Protocol (OCSP) response during a TLS handshake. Due to a logic error in how gnutls processes multi-record OCSP responses, a client with OCSP verification enabled may incorrectly accept a revoked server certificate, potentially leading to a compromise of trust.

CVE-2026-3833: Gnutls: gnutls: policy bypass due to case-sensitive nameconstraints comparison

A flaw was found in gnutls. This vulnerability occurs because gnutls performs case-sensitive comparisons of `nameConstraints` labels, specifically for `dNSName` (DNS) or `rfc822Name` (email) constraints within `excludedSubtrees` or `permittedSubtrees`. A remote attacker can exploit this by crafting a leaf certificate with casing differences in the Subject Alternative Name (SAN), leading to a policy bypass where a certificate that should be rejected is instead accepted. This could result in unauthorized access or information disclosure.

CVE-2026-33845: Gnutls: gnutls: denial of service via dtls zero-length fragment

A flaw in GnuTLS DTLS handshake parsing allows malformed fragments with zero length and non-zero offset, leading to an integer underflow during reassembly and resulting in an out-of-bounds read. This issue is remotely exploitable and may cause information disclosure or denial of service.

CVE-2026-4878: Libcap: libcap: privilege escalation via toctou race condition in cap_set_file()

A flaw was found in libcap. A local unprivileged user can exploit a Time-of-check-to-time-of-use (TOCTOU) race condition in the `cap_set_file()` function. This allows an attacker with write access to a parent directory to redirect file capability updates to an attacker-controlled file. By doing so, capabilities can be injected into or stripped from unintended executables, leading to privilege escalation.

CVE-2026-40552: Remote Code Execution in multiple BinSoft products

Multiple BinSoft products are vulnerable to Remote Command Execution. An authorized user with access to the application and direct access to the backend database can achieve system command execution by uploading an attachment and modifying its storage path in the database to reference an attacker-controlled remote network resource. Alternatively, it is possible to use a previously uploaded file and change its reference. When the application processes the attachment, and a user tries to open it, the referenced resource is executed by the system. Critically, this vulnerability can be exploited by any unauthenticated attacker by chaining it with CVE-2026-40550 and CVE-2026-40551, which allows obtaining database access, and logging onto any account. The described issue affects all published versions. The vendor stated that this issue is a direct result of the architecture model in which the software is distributed, and that it will be mitigated with a corrected installation manual.

CVE-2026-40550: Privilege Escalation in multiple BinSoft products

Multiple BinSoft products are vulnerable to Privilege Escalation due to excessive database privileges assigned to the user used by the application. An attacker with access to any running application instance connected to the backend server can extract database credentials from the application’s memory by inspecting the running process. While ability to retrieve credentials from memory is the expected behavior, the exposed credentials grant administrative access to the database, exceeding the privileges required for normal application functionality. This allows an attacker to perform actions beyond those permitted through the application interface. The described issue affects all published versions. The vendor stated that this issue is a direct result of the architecture model in which the software is distributed, and that it will be mitigated with a corrected installation manual.
