Hi, The following vulnerability was published for gdk-pixbuf. (Choosing RC level, since jmm is planning a DSA, so we should have that fixed as well in trixie) CVE-2025-6199[0]: | A flaw was found in the GIF parser of GdkPixbuf’s LZW decoder. When | an invalid symbol is encountered during decompression, the decoder | sets the reported output size to the full buffer length rather than | the actual number of written bytes. This logic error results in | uninitialized sections of the buffer being included in the output, | potentially leaking arbitrary memory contents in the processed | image. If you fix the vulnerability please also make sure to include the CVE (Common Vulnerabilities & Exposures) id in your changelog entry.
