AI description
CVE-2025-46646 describes a vulnerability found in Artifex Ghostscript, specifically within the `decode_utf8` function located in `base/gp_utf8.c`. This flaw stems from the software's mishandling of overlong UTF-8 encoding when processing certain inputs. The issue is noted as an incomplete fix for a prior vulnerability, CVE-2024-46954. The vulnerability arises due to improper validation of UTF-8 sequences, where the previous fix failed to detect certain 2-byte sequences as overlong. This allows malformed UTF-8 sequences to bypass security checks, potentially leading to the manipulation of text encoding, incorrect processing of UTF-8 characters, or unexpected application behavior. It can also enable path traversal, as well as arbitrary file read, write, and directory listing operations.
- Description
- In Artifex Ghostscript before 10.05.0, decode_utf8 in base/gp_utf8.c mishandles overlong UTF-8 encoding. NOTE: this issue exists because of an incomplete fix for CVE-2024-46954.

Apache FOP + Ghostscript = 💥 Bypassed PostScript escaping using non-breaking spaces (\xa0) to inject commands. Chained with CVE-2025-46646 for Windows RCE. @truffzor Apache won't fix it - just updating the docs 🤷 Full technical details @sigabrt9 https://t.co/iNjDmPLS13
