Prior to 0.14.8413, a crafted pre-R13 DWG can make `decode_preR13_entities()` in `src/decode.c` enter a nonterminating loop that allocates a new object each iteration. `decode_preR13` in `src/decode_r11.c` computes `size` from the raw file-controlled `entities_start` and `entities_end` header bounds; the callee clamps `end` to `dat->size` but never recalculates `size`. At `end` of input, `bit_read_RC` and `bit_read_RS` stop advancing `dat->byte`, the overflow guard fails because `end` equals `dat->size`, and the no-advance check compares against `oldpos` saved before the loop instead of the previous iteration. This leaves repeated allocation of `dwg->object` entries until allocation fails or the process is OOM-killed, not merely a constant-memory CPU hang. The defect remains after the clamping and no-progress changes associated with the earlier issue 1131. Applications and tools calling `dwg_read_file()` on untrusted files, including `dwg2dxf`, `dwgread` and `dwg2svg`, can suffer denial of service when a user or automated pipeline opens a malformed file; no attacker credentials are required. This issue is fixed in repository nightly version 0.14.8413."}],"source":{"advisory":"GHSA-7625-26gc-xqvp","discovery":"UNKNOWN"}},"adp":[{"metrics":[{"other":{"type":"ssvc","content":{"timestamp":"2026-10-30T21:18:21.594623Z","id":"CVE-2026-62250","options":[{"Exploitation":"none"},{"Automatable":"no"},{"Technical Impact":"partial"}],"role":"CISA Coordinator","version":"2.0.3"}}}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2026-10-30T22:12:48.952Z"}}]}}
