Summary
Package updates are available for Amazon Linux 2 that fix the following vulnerabilities: CVE-2026-53705: 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. CVE-2026-39044: An integer overflow in the WAV parser (wavparse) when handling malformed WAV files with cue chunks. The vulnerability occurs during buffer size validation when calculating the expected size for cue entries (ncues * 24), where insufficient bounds checking allows integer overflow during the multiplication operation. (from https://gstreamer.freedesktop.org/security/sa-2026-0021.html) CVE-2026-39043: Heap buffer overflow in the Matroska (MKV) demuxer when calculating decompressed buffer sizes for bz2-compressed tracks. The issue occurs due to missing parentheses in the buffer size calculation, causing incorrect memory allocation and potential out-of-bounds writes.
