Krb5: mit krb5 kadmind authenticated memory exhaustion dos via unbounded rpc xdr allocation

The GSS-RPC layer in MIT Kerberos 5 (aka krb5) does not enforce size limits on XDR-decoded data, which allows remote authenticated users to cause a denial of service (memory exhaustion or excessive CPU consumption in kadmind) via crafted RPC requests that trigger unbounded memory allocations during XDR decoding.

Krb5: mit krb5 kadmind authenticated dos exploiting dereference of null policy name pointers

The policy RPC stubs in kadmin/server/server_stubs.c in MIT Kerberos 5 (aka krb5) 1.5.3 and later do not reject a NULL policy name decoded by xdr_nullstring(), which allows remote authenticated users to cause a denial of service (kadmind crash via NULL pointer dereference) by sending a policy request with an empty policy name that reaches authorization checks or logging code.

CVE-2026-103963

Glib-networking: unbounded tls 1.3 session ticket queue growth in glib-networking allows remote denial of service

A flaw was found in glib-networking. When establishing connections using Transport Layer Security (TLS) version 1.3, the client-side session cache does not limit the number of session tickets retained for a single host. A malicious server can exploit this by sending excessive session ticket messages, causing the client application to continuously consume memory. This unbounded memory growth can exhaust system memory, resulting in a Denial of Service (DoS).

A flaw was found in the xfs_admin utility in xfsprogs. The tool does not properly validate user-supplied parameters, allowing operating system command injection. A local attacker can exploit this issue by providing crafted input arguments, which may result in arbitrary command execution and local privilege escalation depending on how xfs_admin is executed.

Busybox: out-of-bounds read in volume_id_get_buffer() via an offset+length wraparound

A flaw was found in BusyBox. An integer overflow occurs in the volume_id component when calculating buffer boundaries while probing filesystem metadata. An attacker can exploit this vulnerability by providing a specially crafted filesystem image on an attached storage device. When probed by utilities such as blkid, findfs, or mount, the application crashes, resulting in a Denial of Service (DoS) that prevents the system from resolving or mounting storage devices.

Openscap: openscap: arbitrary file write via path traversal in source datastream decomposition

A flaw was found in OpenSCAP. When decomposing a Source DataStream (SDS) file, the application does not properly validate relative file path attributes, leading to a path traversal vulnerability. An attacker can exploit this flaw by tricking a user or automated system into decomposing a crafted datastream containing directory traversal sequences. Successful exploitation allows unauthorized file creation or modification outside the intended target directory with the permissions of the executing process.

Busybox: cpio hardlink target not sanitized under feature_path_traversal_protection

A flaw was found in BusyBox. When extracting files using the cpio utility with path traversal protection enabled, hardlink target paths are not properly sanitized. By tricking a user or automated process into extracting a crafted archive, an attacker can create hardlinks that point to files outside the intended extraction directory. This issue may allow an attacker to modify or overwrite arbitrary files outside the target directory during subsequent extraction operations.

Patch: filename validation bypass in reversal fallback allows file creation outside the working directory

A flaw was found in GNU patch. An attacker can achieve arbitrary file creation outside the intended working directory by enticing a user or automated workflow to apply a specially crafted patch file. Due to missing validation during automatic patch reversal, absolute file paths in patch headers are accepted rather than rejected. Consequently, the utility can create files in arbitrary locations with the permissions of the executing user.

Gst-plugins-good: gst-plugins-good: local file disclosure via unvalidated file:// uris in adaptivedemux2 manifest handling

A flaw was found in GStreamer's adaptive streaming demuxers (HLS, DASH, MSS). When processing a media playlist or manifest, URIs referenced in the manifest content are fetched without restricting which URI schemes are permitted. An attacker who controls a manifest URL, or who can inject content into an HTTP manifest response, can include file:// URIs pointing to arbitrary local files, causing the affected application to read and process those files. In automated or server-side deployments such as media recorders, proxies, and downloaders, this can lead to disclosure of sensitive local files. Existence of files can also be inferred through differing error responses even when content is not directly observable.

A flaw was found in gnome-remote-desktop as shipped in Red Hat Enterprise Linux. In the VNC TLS I/O handlers, retryable GnuTLS results (GNUTLS_E_AGAIN and GNUTLS_E_INTERRUPTED) are handled with an unbounded busy loop instead of yielding to the event loop. A remote attacker who can reach an enabled VNC TLS listener can cause the event-loop thread to spin at high CPU with no forward progress, resulting in denial of service.

Environment-modules: command injection in environment-modules bash completion via malicious module names containing shell metacharacters

A flaw was found in environment-modules. A local attacker can exploit this vulnerability by placing a maliciously named modulefile in a location visible to the victim's `MODULEPATH`. When the victim uses Bash completion for `module` or `ml` commands, the malicious module name, containing shell metacharacters, is evaluated as a command. This can lead to arbitrary command execution in the completing user's shell, impacting their confidentiality, integrity, and availability.
