Synopsis
The remote Amazon Linux 2 host is missing a security update.Description
The version of gstreamer1-plugins-base installed on the remote host is prior to 1.18.4-5. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2-2025-2747 advisory.GStreamer is a library for constructing graphs of media-handling components. A stack-buffer overflow has been detected in the `vorbis_handle_identification_packet` function within `gstvorbisdec.c`. The position array is a stack-allocated buffer of size 64. If vd->vi.channels exceeds 64, the for loop will write beyond the boundaries of the position array. The value written will always be `GST_AUDIO_CHANNEL_POSITION_NONE`. This vulnerability allows someone to overwrite the EIP address allocated in the stack. Additionally, this bug can overwrite the `GstAudioInfo` info structure. This vulnerability is fixed in 1.24.10. (CVE-2024-47538)
GStreamer is a library for constructing graphs of media-handling components. stack-buffer overflow has been detected in the gst_opus_dec_parse_header function within `gstopusdec.c'. The pos array is a stack- allocated buffer of size 64. If n_channels exceeds 64, the for loop will write beyond the boundaries of the pos array. The value written will always be GST_AUDIO_CHANNEL_POSITION_NONE. This bug allows to overwrite the EIP address allocated in the stack. This vulnerability is fixed in 1.24.10. (CVE-2024-47607)
GStreamer is a library for constructing graphs of media-handling components. An OOB-Write has been detected in the function gst_parse_vorbis_setup_packet within vorbis_parse.c. The integer size is read from the input file without proper validation. As a result, size can exceed the fixed size of the pad->vorbis_mode_sizes array (which size is 256). When this happens, the for loop overwrites the entire pad structure with 0s and 1s, affecting adjacent memory as well. This OOB-write can overwrite up to 380 bytes of memory beyond the boundaries of the pad->vorbis_mode_sizes array. This vulnerability is fixed in 1.24.10. (CVE-2024-47615)
Tenable has extracted the preceding description block directly from the tested product security advisory.
Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
