The version of gstreamer-plugins-bad-free installed on the remote host is prior to 0.10.23-42. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2-2026-3791 advisory.

    A heap buffer overflow vulnerability was found in GStreamer's librfb (RFB/VNC client). The rectangle     bounds check incorrectly validates area rather than individual dimensions, allowing a malicious VNC server     to send a rectangle that extends beyond the framebuffer. A remote attacker could set up a malicious VNC     server and trick a user into connecting, resulting in an out-of-bounds heap write that could lead to code     execution or a crash. (CVE-2026-52720)

    Multiple out-of-bounds read vulnerabilities were found in GStreamer's pcapparse element. Malformed PCAP     records can trigger reads beyond buffer boundaries during IPv4/TCP header parsing. This element is     primarily used in debugging pipelines, limiting real-world exposure. A local attacker could trick a user     into processing a specially crafted PCAP file, potentially leading to a crash or information disclosure.
    (CVE-2026-52721)

    A signed integer overflow vulnerability was found in GStreamer's VMnc decoder. A crafted VMnc stream with     large cursor dimensions can overflow signed integer payload-size arithmetic, bypassing a length check and     leading to out-of-bounds reads. A remote attacker could trick a user into opening a specially crafted VMnc     file, potentially causing a crash or information disclosure. (CVE-2026-52722)

The remote Redhat Enterprise Linux 10 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2026:36749 advisory.

    GStreamer is a streaming media framework based on graphs of filters which operate on media data. The     gstreamer1-plugins-bad-free package contains a collection of plug-ins for GStreamer.

    Security Fix(es):

    * gstreamer1-plugins-bad-free: GStreamer: Denial of service via AV1 tile_list_obu parser byte/bit     confusion (CVE-2026-52718)

    * gstreamer1-plugins-bad-free: GStreamer: Out-of-bounds read via JPEG segment length validation in VA     decoder (CVE-2026-52719)

It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2023-2026-1917 advisory.

    A denial of service vulnerability was found in GStreamer's AV1 codec parser in gst-plugins-bad. The     gst_av1_parser_parse_tile_list_obu() function passes a byte count to a bit-reader API that expects a bit     count, causing parser desynchronization. A remote attacker could trick a user into opening a specially     crafted AV1 media file, triggering an assertion abort and causing the application to crash.
    (CVE-2026-52718)

    An out-of-bounds read vulnerability was found in the VA JPEG decoder in GStreamer's gst-plugins-bad. The     JPEG parser reads a segment length value from the bitstream without validating it against available data.
    A remote attacker could trick a user into opening a specially crafted JPEG file, causing downstream     parsing to read beyond the provided input buffer, leading to a crash or potential information disclosure.
    (CVE-2026-52719)

    A heap buffer overflow vulnerability was found in GStreamer's librfb (RFB/VNC client). The rectangle     bounds check incorrectly validates area rather than individual dimensions, allowing a malicious VNC server     to send a rectangle that extends beyond the framebuffer. A remote attacker could set up a malicious VNC     server and trick a user into connecting, resulting in an out-of-bounds heap write that could lead to code     execution or a crash.

A local attacker could trick a user     into processing a specially crafted PCAP file, potentially leading to a crash or information disclosure.
    (CVE-2026-52721)

    A signed integer overflow vulnerability was found in GStreamer's VMnc decoder. A crafted VMnc stream with     large cursor dimensions can overflow signed integer payload-size arithmetic, bypassing a length check and     leading to out-of-bounds reads. A remote attacker could trick a user into opening a specially crafted VMnc     file, potentially causing a crash or information disclosure. (CVE-2026-52722)

    A stack buffer overflow flaw was found in the GStreamer H.265 codec parser library (gst-plugins-bad). When     parsing a buffering period SEI message, the parser uses an incorrect loop bound derived from     cpb_cnt_minus1[i] (the loop index) instead of the sub-layer 0 CPB count cpb_cnt_minus1[0] from the     referenced Sequence Parameter Set. A crafted H.265 video file or stream can cause the parser to write     beyond the bounds of stack-allocated CPB delay arrays, resulting in a crash or potential stack memory     corruption. (CVE-2026-53702)
