It was discovered that the ghostscript /invalidaccess checks fail under certain conditions. An attacker could possibly exploit this to bypass the -dSAFER protection and, for example, execute arbitrary shell commands via a specially crafted PostScript document.

Removed below patches, as v9.25 source already has those changes/security fixes: 0001-Bug-699665-memory-corruption-in-aesdecode.patch 0001-pdfwrite-Guard-against-trying-to-output-an-infinite-.patch 0002-Bug-699656-Handle-LockDistillerParams-not-being-a-bo.patch 0003-Fix-Bug-699660-shading_param-incomplete-type-checkin.patch 0004-Hide-the-.shfill-operator.patch 0005-Bug-699657-properly-apply-file-permissions-to-.tempf.patch remove-direct-symlink.patch Re-worked ghostscript-9.21-native-fix-disable-system-libtiff.patch and ghostscript-9.21-prevent_recompiling.patch to fix warnings in do_patch task of ghostscript v9.25 recipe. Highlights of ghostscript v9.25 release: --------------------------------------- - This release fixes problems with argument handling, some unintended results of the security fixes to the SAFER file access restrictions (specifically accessing ICC profile files), and some additional security issues over the recent 9.24 release. - Note: The ps2epsi utility does not, and cannot call Ghostscript with the -dSAFER command line option. It should never be called with input from untrusted sources. - Security issues have been the primary focus of this release, including solving several (well publicised) real and potential exploits. - As well as Ghostscript itself, jbig2dec has had a significant amount of work improving its robustness in the face of out specification files. - IMPORTANT: We are in the process of forking LittleCMS. LCMS2 is not thread safe, and cannot be made thread safe without breaking the ABI. Our fork will be thread safe, and include performance enhancements (these changes have all be been offered and rejected upstream). We will maintain compatibility between Ghostscript and LCMS2 for a time, but not in perpetuity. Our fork will be available as its own package separately from Ghostscript (and MuPDF). - The usual round of bug fixes, compatibility changes, and incremental improvements.

The patch was adding a change to the source file that was already there, so the lines of code were repeated twice. This didn't create a bug or a security issue, but it may well have.
