Summary
A flaw was found in GStreamer's WavPack audio decoder in gst-plugins-good. An integer overflow in buffer size calculation (4 * block_samples * channels) in gst_wavpack_dec_handle_frame() causes a very small heap allocation, leading to heap memory corruption when decoded audio samples are written beyond the allocated buffer. This affects both 32-bit and 64-bit systems as the arithmetic is performed in 32-bit integers before promotion to the allocation size type.
Risk Assessment
A remote attacker could exploit this flaw to crash an application or potentially execute arbitrary code by convincing a user to open a malicious WavPack audio file. This poses a significant risk to systems processing multimedia content.
Recommendation
Immediately update GStreamer packages (gst-plugins-good) to a version containing the fix for the integer overflow. Until updated, avoid opening WavPack files from untrusted sources.
Other vulnerabilities in GStreamer
See all- CVE-2026-17072Low
In GStreamer's gst-plugins-good, a heap-based out-of-bounds read of 4 bytes occurs when parsing FLAC audio stream headers embedded in Matroska or WebM container files. A boundary check does not account for the full size of the copied data, allowing a small read past the end of the allocated buffer. An attacker can exploit this by crafting a malicious Matroska or WebM file and tricking a user into opening it.
- CVE-2017-5843High
Multiple use-after-free vulnerabilities in the gst_mini_object_unref, gst_tag_list_unref, and gst_mxf_demux_update_essence_tracks functions in GStreamer before 1.10.3 allow remote attackers to cause a denial of service (crash) via vectors involving stream tags.
- CVE-2017-5840High
The qtdemux_parse_samples function in gst/isomp4/qtdemux.c in GStreamer before version 1.10.3 allows remote attackers to cause a denial of service (out-of-bounds heap read) via vectors involving the current stts index.
- CVE-2017-5838High
The gst_date_time_new_from_iso8601_string function in GStreamer before version 1.10.3 allows remote attackers to cause a denial of service via a malformed datetime string, leading to an out-of-bounds heap read.
- CVE-2016-9447High
The ROM mappings in the NSF decoder in gstreamer 0.10.x allow remote attackers to cause a denial of service (out-of-bounds read or write) and possibly execute arbitrary code via a crafted NSF music file.
- CVE-2016-9446High
The vmnc decoder in gstreamer does not initialize the render canvas, allowing remote attackers to obtain sensitive information. This is demonstrated by thumbnailing a simple 1 frame vmnc movie that does not draw to the allocated render canvas.
- CVE-2016-9445High
Integer overflow in the vmnc decoder in gstreamer allows remote attackers to cause a denial of service (crash) via large width and height values, which triggers a buffer overflow.
- CVE-2016-9809High
Off-by-one error in the gst_h264_parse_set_caps function in GStreamer before version 1.10.2 allows remote attackers to have unspecified impact via a crafted file, leading to an out-of-bounds read.
- CVE-2016-9808High
The FLIC decoder in GStreamer before 1.10.2 allows remote attackers to cause a denial of service (out-of-bounds write and crash) via a crafted series of skip and count pairs.
- CVE-2026-18299High
Use-After-Free vulnerability in GStreamer rtpsbcdepay allows remote code execution. Lack of validating object existence before operations leads to use-after-free. An attacker can leverage this to execute code in the context of the current process.
Original NVD description (English source)
A flaw was found in GStreamer's WavPack audio decoder in gst-plugins-good. When processing a specially crafted WavPack file, an integer overflow in the buffer size calculation (4 * block_samples * channels) in gst_wavpack_dec_handle_frame() causes a very small heap allocation. The WavPack library then writes decoded audio samples far beyond the allocated buffer, resulting in heap memory corruption. This affects both 32-bit and 64-bit systems since the arithmetic is performed in 32-bit integers before promotion to the allocation size type. A remote attacker could use this flaw to crash an application or potentially execute arbitrary code by convincing a user to open a malicious WavPack audio file.
