Client-Side Memory Leak in OCSP Response Checking

Issue summary: A malicious TLS server can cause a memory leak in a TLS client that has enabled OCSP response checking by sending an OCSP response that contains no single response entries. Impact summary: An attacker can leak an attacker-tunable amount of memory per TLS handshake in a victim client application. A long-running client that repeatedly connects to a malicious server can have its memory exhausted, resulting in a Denial of Service. CWE: CWE-401: Missing Release of Memory after Effective Lifetime Description: The affected function is called during X.509 certificate chain verification when OCSP response checking is enabled with the X509_V_FLAG_OCSP_RESP_CHECK or X509_V_FLAG_OCSP_RESP_CHECK_ALL verification flags, for example when a TLS client verifies an OCSP response stapled into the TLS handshake by the server. When the received BasicOCSPResponse contains an empty SEQUENCE OF SingleResponse, which is permitted on the wire and accepted by the OpenSSL decoder, the OCSP_BASICRESP structure allocated by OCSP_response_get1_basic() was not freed because an early return bypassed the cleanup code at the end of the function. The amount of memory leaked per handshake can be amplified by the attacker by padding the certs field of the BasicOCSPResponse with bogus certificates, which are parsed and stored in the leaked structure before the empty response check triggers the early return. A long-running TLS client that repeatedly connects to a malicious server can have its memory exhausted over time. OCSP response checking is not enabled by default. Only client applications that explicitly enable the OCSP response check verification flags are affected. FIPS impact: no The FIPS modules in 4.0 and 3.6 are not affected by this issue as the affected code is outside the OpenSSL FIPS module boundary.

Flatpak: flatpak: denial of service via unsanitized keys in exported desktop entry / d-bus service files

Flatpak passes through arbitrary vendor-extension keys unmodified when exporting an application's Desktop Entry (.desktop) and D-Bus Service (.service) files, instead of validating against an allowlist. A malicious Flatpak app can use this to cause denial of service (e.g. forced application restart loops) or to influence host D-Bus/systemd activation behavior beyond what the sandbox is intended to permit.

Flatpak: flatpak: world-writable temporary child repositories in system-helper cache path

Flatpak creates temporary child repository directories under the user cache with world-writable permissions (0777). On multi-user systems with a permissive umask, other local users could read or modify the temporary directory used while installing apps or runtimes, potentially causing installation failures (denial of service); tampered content would fail signature/digest verification rather than being trusted.

Flatpak: flatpak: world-readable oci authentication token in system-helper cache path

Flatpak writes the OCI repository authentication token with world-readable permissions (0644) in the system-helper's cache directory, allowing other local users on a multi-user system to read the token and impersonate the authenticated user against the OCI repository. Only OCI-based sources (e.g. as used by Fedora) are affected; libostree-based sources such as Flathub are not.

Gimp: gimp: one-byte out-of-bounds heap read in the uncompressed dds loader

A one-byte out-of-bounds heap read flaw was found in GIMP's uncompressed DDS image loader. When a user opens an uncompressed DDS image, the file-dds plug-in performs an unconditional one-byte look-ahead after processing the final pixel. This may cause the plug-in to crash if the byte immediately following the pixel buffer is inaccessible; no information disclosure or code execution has been demonstrated.

Flatpak: flatpak: arbitrary read-access to files in the system-helper context via oci symlink following

A malicious user can get read-access to files in the flatpak-system-helper context if a system OCI repository is configured, because the OCI code paths in the system helper follow symlinks when importing OCI images that are under the user's control.

Flatpak: flatpak: flatpak-system-helper cross-user cancelpull orphans another user's ongoing pull

By calling org.freedesktop.Flatpak.SystemHelper.CancelPull on another user's pull, the pull is not actually cancelled but removed from internal tracking, making it impossible for the owning user to stop it. Ongoing pulls cannot be stopped.

Flatpak: flatpak: extension metadata path traversal file existence oracle

A malicious Flatpak extension can probe the host filesystem to determine what files and directories exist at arbitrary paths, and host directory listings can be disclosed to sandboxed applications using the extension. Additionally, unvalidated extension metadata can cause extension content to be mounted at unintended locations inside the sandbox.

Improper input handling in Secure Access servers

CVE-2026-116767 is an improper input handling vulnerability in Secure Access servers prior to 14.61. Authenticated attackers can cause a persistent denial of service.

Dnsmasq: dnsmasq: heap out-of-bounds read in dhcpv6 option 39 fqdn decoder

A flaw was found in dnsmasq. The DHCPv6 client hostname parser can read one byte past the end of a crafted FQDN option because it checks the next label length before confirming the pointer is still inside the option. An attacker on the local network can trigger this with a single DHCPv6 packet. The extra byte is not returned to the client or logged, and no crash has been demonstrated.

Dnsmasq: dnsmasq: --leasequery without address argument applies no source address check

A flaw was found in dnsmasq. When DHCP leasequery is enabled without listing allowed source addresses, the server does not check who sent the query. A host on the local network can request DHCP lease records and learn assigned addresses, MAC addresses, hostnames, and related lease metadata. The feature is off unless an administrator turns it on.

Cockpit: cockpit: unauthorized modification of login records via integer overflow

A flaw was found in Cockpit. An authenticated local user with a large user identifier (UID) can cause unauthorized modification and disclosure of login records. On 32-bit systems, an integer overflow during session accounting allows the user's login process to read or overwrite the legacy log entries of other accounts.

Sssd: local oob read in nss service request parsers (`sss_nss_protocol_parse_svc_name` / `sss_nss_protocol_parse_svc_port`)

A flaw was found in the sssd NSS responder. This input validation vulnerability allows a local attacker, by sending specially crafted service lookup requests to the NSS responder's UNIX socket, to cause an out-of-bounds read. This out-of-bounds read may lead to a denial of service (DoS) by crashing the NSS responder process. While unprivileged local clients can typically reach the socket, there is no evidence of privilege escalation or reliable data disclosure.

WhatsUp Gold versions prior to 26.0.2 contain an unauthenticated remote code execution vulnerability in an internal report scheduling service.

In WhatsUp Gold versions released before 2026.0.2, an unauthenticated remote attacker with network access to the affected service can execute arbitrary code in the context of the IIS application service account.

Cups: openprinting cups: remaining case-insensitive username matching in scheduler side paths (cve-2026-27447 follow-up)

Two case-insensitive comparisons on request-derived usernames outside the main authorization path in CUPS's scheduler (printer ACL validation and private-attribute filtering) could allow bypass of username-based access controls in certain configurations.

Polkit: regression in cve-2026-4897 fix (polkit read_cookie()) - stack buffer underflow

A flaw was found in polkit. When processing input that begins with a null byte, an arithmetic error in the authentication agent helper causes an integer underflow during buffer length calculation, resulting in an out-of-bounds memory read. An attacker capable of supplying crafted input can trigger this flaw, potentially causing an application crash and resulting in a Denial of Service (DoS).

Org.wildfly.core: wildfly: path traversal in take-snapshot discloses the server configuration to the monitor role

A flaw was found in WildFly. A user with the `Monitor` role, which is the lowest standard Role-Based Access Control (RBAC) role, can exploit a path traversal vulnerability in the `take-snapshot` operation. By manipulating the `name` parameter, this user can write a copy of the server configuration to an arbitrary location. This allows the `Monitor` role to read back the server configuration, including sensitive credentials, which would otherwise be restricted by RBAC, leading to information disclosure.
