Gimp: gimp: heap buffer overflow in dicom export on oversized image dimensions

A heap-based buffer overflow was found in GIMP’s DICOM export plug-in. When exporting an image with extremely large width and height, the export path allocates a buffer using a 32-bit width * height (and bytes-per-pixel) product that can overflow. GEGL then writes the full uncompressed extent into the undersized buffer, after integer overflow in the allocation size

CVE-2026-106061

Gimp: gimp: heap buffer over-read in x cursor (xmc) thumbnail loader on crafted file

A flaw was found in GIMP’s X cursor (XMC) thumbnail loader. When GIMP generates a thumbnail for a crafted XMC file, it allocates a pixel buffer using a width * height size computed in 32-bit signed arithmetic. If that product overflows, the allocation is smaller than the true image extent. A subsequent GEGL buffer read uses the unwrapped dimensions and performs an out-of-bounds read on the heap, after integer overflow in the size calculation. This can crash GIMP or corrupt process memory.

CVE-2026-104046

Sssd: sssd: denial of service via incomplete identity provider authentication requests

A flaw was found in SSSD (System Security Services Daemon). When Identity Provider (IdP) authentication is enabled, pre-authentication requests retain state in memory without being cleared or timed out. A local attacker can repeatedly initiate authentication flows without completing them, causing unbounded memory consumption. This memory exhaustion can lead to a Denial of Service (DoS) by degrading or terminating SSSD authentication services.

Sssd: sssd: denial of service via crafted passkey kerberos authentication request

A flaw was found in sssd. A local attacker can trigger a Denial of Service (DoS) by sending a specially crafted Pluggable Authentication Module (PAM) request when passkey authentication is enabled. Due to a missing state validation check in passkey Kerberos handling, the PAM responder dereferences an uninitialized pointer and crashes. This failure disrupts authentication services on the host.

Sssd: sssd: denial of service via out-of-bounds read in pam responder

A flaw was found in sssd. A local attacker can cause a Denial of Service (DoS) by sending a crafted Pluggable Authentication Module (PAM) request containing a zero-length authentication token to the responder socket. Due to missing input validation, the service attempts to read beyond buffer boundaries when processing the token, causing the PAM responder to crash.

CVE-2026-104041

Sssd: sssd: denial of service via unbounded negative cache growth

A flaw was found in SSSD. An unprivileged local user can repeatedly request lookups for nonexistent entries through the Name Service Switch (NSS) responder. Because the negative cache does not limit the total number of stored entries and only removes expired records when an existing key is rechecked, the cache can grow without bound. This behavior can lead to memory exhaustion, resulting in a Denial of Service (DoS) as the responder becomes unresponsive or terminates.

Sssd: sssd: denial of service via stale connection state reuse in pam gssapi responder

A flaw was found in SSSD. A local user can cause a denial of service (DoS) by disrupting system authentication services. When handling Generic Security Services Application Programming Interface (GSSAPI) authentication in the Pluggable Authentication Module (PAM) responder, cached connection state is freed upon completion without clearing the reference pointer. An attacker can exploit this by sending an additional request over the same connection, causing the service to access invalid memory and unexpectedly terminate.
