Jwcrypto: jwcrypto: denial of service via o(n^2) duplicate check on unbounded jwk key_ops array

A flaw was found in jwcrypto. The JWK.import_key() function validates the key_ops JWK member for duplicate values using an algorithm with O(n^2) time complexity, and the length of key_ops is not bounded. A remote, unauthenticated attacker can supply a JWK with a large key_ops array to an application that passes attacker-controlled key material to a public key-import API (reachable via ECDH-ES key agreement, OIDC dynamic client registration, DPoP, or ACME account key registration, among others) to consume excessive CPU time, resulting in a denial of service.

Jwcrypto: jwcrypto: denial of service via malformed jwe tokens

A flaw was found in jwcrypto. A remote attacker can send a specially crafted JSON Web Encryption (JWE) token containing numerous period delimiters. This malformed token can force the JWE.deserialize() function to allocate excessive memory, leading to a MemoryError. This issue results in a denial of service (DoS) for services that process untrusted JWE values.

Sos: sos: path traversal in sos clean tar extraction via unvalidated symlink/hardlink targets leads to arbitrary file write

A flaw was found in sos clean, a utility within the sos package. This vulnerability allows a local attacker to perform arbitrary file creation or overwrite. By crafting a malicious tar archive, an attacker can exploit a path traversal issue during tar extraction, where symlink and hardlink targets are not properly validated. This enables the attacker to write files to arbitrary locations on the system with the privileges of the sos clean process, which often runs as root.

Keycloak-services: keycloak-services: delegated admin escalates to realm-admin via group move

A flaw was found in the group-move and organization group reparenting endpoints of the keycloak-services component. This component is responsible for core authentication and authorization services in the Red Hat build of Keycloak. The issue occurs because the system fails to check if a target parent group confers administrative roles when a group is moved. A delegated administrator can exploit this to move a group they control under an administrative group, causing all members to inherit full realm-admin privileges and gain complete control over the realm.

Quarkus-rest-data-panache: quarkus-rest-data-panache: getter-level @securefield ignored for filter and sort

A flaw was found in the REST Data Panache component of Quarkus. When a security constraint is applied to an entity property using the @SecureField annotation on its getter method rather than the field itself, the generated REST resource fails to enforce this constraint for filtering and sorting operations. This allows an authenticated user to infer sensitive data values by observing which records match specific filter criteria or how they are ordered, even though the values are omitted from the final response.

Libarchive: heap overflow oob read while parsing a tar archive contains a pax extended header

A flaw was found in libarchive. This vulnerability allows a remote attacker to trigger a heap overflow by providing a specially crafted tar archive. The issue occurs during the parsing of a PAX extended header containing a malformed SUN.holesdata sparse-file attribute. Successful exploitation could lead to a denial of service, making the system unavailable, or potentially allow for arbitrary code execution, giving the attacker control over the affected system.

The fix for CVE-2026-0716 (commit 6ff7ef0, libsoup 3.6.6) placed the integer overflow guard inside the if (masked) block, leaving unmasked server-to-client frames unprotected. A malicious WebSocket server can send a crafted unmasked frame with a payload length near UINT64_MAX to trigger an OOB read in a libsoup-based client when max_incoming_payload_size is set to 0.

Kronosnet: kronosnet: encryption key exposure in memory after cryptographic configuration changes

A vulnerability was found in kronosnet's (version <=1.34) cryptographic configuration management. The framework does not correctly zero-out or wipe sensitive memory segments after executing changes to its cryptographic configuration. This omission leaves raw encryption keys resident in memory after the associated structures are freed. A local attacker capable of leveraging memory disclosure techniques could exploit this flaw to retrieve the active encryption key, allowing them to decrypt cluster network communications or inject malicious packets to cause severe high-availability cluster instability.

A stack-based buffer overflow was found in rpcbind's rpcinfo utility. In rpcbdump() short mode (used by `rpcinfo -s`), version numbers from a remote RPCBPROC_DUMP reply are written into a fixed-size stack buffer without bounds checking.

Cri-o: cri-o: unvalidated image env var causes daemon crash

A flaw was found in CRI-O's container-creation environment-variable handling (`mergeEnvs` in `server/utils.go`, consumed by `setupContainerEnvironmentAndWorkdir` in `server/container_create.go`). When a `CreateContainer` request supplies a `nil` CRI `Envs` field, CRI-O falls back to using the target OCI image's `config.Env` entries unfiltered, in contrast to the normal merge path, which validates each entry for a `key=value` form before use. An OCI image whose `config.Env` contains an entry with no `=` character (e.g. a bare `NOEQUALS` string) causes CRI-O to split that entry into a single-element slice and then index its second element, which is out of range. This triggers an unrecovered Go runtime panic in the `crio` daemon process, crashing it and terminating the container-runtime service for all workloads on the node until it is restarted.

Gimp: multiple heap out-of-bounds reads in xwd loader from unrelated width and bytes-per-line validation

A flaw was found in the file-xwd plugin in GIMP. When processing a specially crafted XWD image file, the plugin validates the image width and bytes-per-line parameters independently rather than ensuring their combined values are consistent with the allocated buffer size. This incorrect validation leads to improper bounds checking, causing a heap out-of-bounds read. This issue can result in an application crash, leading to a denial of service or a limited information disclosure of heap memory contents into the produced image.

Python-pulpcore: pulpcore: header content guard jq filter exposes the content-app environment

An **expression language injection** has been found in the HeaderContentGuard.permit function in publication.py of the content guard in the **Pulpcore** package. The guard is supposed to check a value in a request header. It saves a jq filter and runs that filter against the header when a client asks for content. The filter is not limited to the header, and jq's env builtin also returns the environment of the content process. A low-privileged network attacker or user who can create a header content guard and attach it to a distribution can save a filter that reads that environment. The content request is allowed or denied according to the filter result. Repeating the request lets that attacker or user recover the environment, including Pulp settings held there, such as the Django secret key or the database password.

Gdk-pixbuf: gdk-pixbuf: heap out-of-bounds read in uncompress() via crafted icns rle block

A flaw was found in gdk-pixbuf. This vulnerability allows a remote attacker to cause a heap out-of-bounds read by providing a specially crafted Apple Icon Image (.icns) file. The uncompress() function, which handles RLE-encoded ICNS icon data, fails to validate the source buffer's boundaries during decompression. This can lead to a denial of service, where the application crashes, or to information disclosure, potentially revealing sensitive data from adjacent memory.

A flaw was found in sssd, specifically within the PAM (Pluggable Authentication Modules) responder's protocol v1 parser, pam_parse_in_data(). A local client with access to the PAM responder's UNIX socket can exploit this by negotiating protocol v1 and sending an empty or truncated PAM request body. This can trigger an out-of-bounds read, potentially causing the PAM responder to terminate or restart, leading to a local denial of service.

A flaw was found in GNOME Shell. When processing icons from a remote search provider via D-Bus, the system fails to validate the icon's declared dimensions against the actual data buffer size. A malicious or compromised remote search provider could exploit this by providing oversized icon dimensions, leading to an out-of-bounds read. This can cause the GNOME Shell process to crash, disrupting the user's session, and potentially disclose sensitive information from adjacent memory.
