Descripción resumida

WatchGuard Fireware OS iked process contains an out of bounds write vulnerability in the OS iked process. This vulnerability may allow a remote unauthenticated attacker to execute arbitrary code and affects both the mobile user VPN with IKEv2 and the branch office VPN using IKEv2 when configured with a dynamic gateway peer.

Acción requerida

Apply mitigations per vendor instructions, follow applicable BOD 22-01 guidance for cloud services, or discontinue use of the product if mitigations are unavailable.

Notas

Check for signs of potential compromise on all internet accessible instances after applying mitigations. For more information please see: https://www.watchguard.com/wgrd-psirt/advisory/wgsa-2025-00027 ; https://nvd.nist.gov/vuln/detail/CVE-2025-14733

Descripción técnica

An Out-of-bounds Write vulnerability in the WatchGuard Fireware OS iked process may allow a remote unauthenticated attacker to execute arbitrary code. This vulnerability affects both the mobile user VPN with IKEv2 and the branch office VPN using IKEv2 when configured with a dynamic gateway peer. If the Firebox was previously configured with the mobile user VPN with IKEv2 or a branch office VPN using IKEv2 to a dynamic gateway peer, and both of those configurations have since been deleted, that Firebox may still be vulnerable if a branch office VPN to a static gateway peer is still configured.

CVE-2026-111458—

———The fanx_fingerprint function in ssl/sslxprint.c of ssldump allocates a heap buffer for formatting FAN/1 X.509 certificate fingerprints. The allocation size is computed as strlen(b64) + strlen(hex) + 31, but the format string "fan1:x509:server:passive:%s:sha256:%s" contains 33 fixed characters in addition to the two variable-length fields and a null terminator, requiring strlen(b64) + strlen(hex) + 34 bytes. This miscalculation results in a 3-byte heap-based buffer overflow on every invocation of the function with valid inputs. The overflow occurs because sprintf writes the full formatted string into the undersized heap buffer without bounds checking. An attacker who can supply a crafted pcap file containing a TLS X.509 certificate to a user running ssldump with FAN/1 fingerprinting enabled (for example with the -j -N options) can trigger the overflow. The resulting heap corruption may lead to denial of service through a crash or, in a worst-case scenario, arbitrary code execution in the context of the user running ssldump. The vulnerability is deterministic and requires no special privileges beyond the ability to provide input to the tool.4h CVE-2026-1113828.8 ALT

———FreeRDP before 3.32.0 contains a client-side heap out-of-bounds write vulnerability in general_LumaToYUV444 and general_ChromaV2ToYUV444 that allows malicious RDP servers to corrupt client memory. Attackers can send RDPGFX AVC444 or AVC444v2 frames with odd-height region rects ending at surface height to write past U/V planes, enabling heap corruption and potential code execution.7h CVE-2026-890625.5 MED

———snap7 through 1.4.3 contains an out-of-bounds write vulnerability in TSnap7MicroClient::opReadArea() that allows malicious S7 peers to overflow client buffers via an unchecked DataLength field. Rogue or impersonated PLCs can return crafted ReadVar responses causing memcpy of up to 65535 bytes into caller buffers, crashing SCADA, HMI, or gateway processes and corrupting memory.12h CVE-2026-1112756.1 MED

—

———nifti_clib through 3.0.1 contains a stack-based out-of-bounds read and write vulnerability in nifti_convert_n2hdr2nim() because the NIfTI-2 dim[0] value is never range-checked. Attackers can supply a crafted 540-byte NIfTI-2 header read via nifti_image_read() to crash applications or corrupt stack memory.12h CVE-2026-1112706.1 MED

—

———libmodplug through 0.8.9.1 contains a heap-based out-of-bounds write in CSoundFile::ReadDSM() in src/load_dsm.cpp because nPat is never checked against MAX_PATTERNS. Attackers can supply a crafted DSM file with over 240 PATT chunks or a wrapping patt_len value to corrupt heap memory and crash the consuming process.12h
