An incomplete fix for CVE-2024-47778 allows an out-of-bounds read in gst_wavparse_adtl_chunk() function. The patch added a size validation check lsize + 8 > size, but it does not account for the GST_ROUND_UP_2(lsize) used in the actual offset calculation. When lsize is an odd number, the parser advances more bytes than validated, causing OOB read.

There are packages installed that are affected by a vulnerability referenced in the following CVE:

    Multiple security vulnerabilities were discovered in plugins for the     GStreamer media framework and its codecs and demuxers, which may result     in denial of service or potentially the execution of arbitrary code if     a malformed media file is opened.

    For the stable distribution (trixie), these problems have been fixed in     version 1.26.2-1+deb13u2.

    We recommend that you upgrade your gst-plugins-good1.0 packages.
