gstreamer1-plugins-good: integer overflows in MP4/MOV demuxer and memory allocator that can lead to out-of-bounds writes

A flaw was found in the MP4/MOV demuxer and memory allocator in the GStreamer library. Processing a specially crafted input file can cause an integer overflow in the qtdemuxparsetheoraextension function. This issue leads to a small amount of memory being allocated to store a large input size,...

CVE-2024-47606 GHSL-2024-166: GStreamer Integer overflows in MP4/MOV demuxer and memory allocator that can lead to out-of-bounds writes

GStreamer is a library for constructing graphs of media-handling components. An integer underflow has been detected in the function qtdemuxparsetheoraextension within qtdemux.c. The vulnerability occurs due to an underflow of the gint size variable, which causes size to hold a large unintended...

FreeBSD : FreeBSD -- Unbounded allocation in ctl(4) CAM Target Layer (8caa5d60-a174-11ef-9a62-002590c1f29c)

The version of FreeBSD installed on the remote host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the 8caa5d60-a174-11ef-9a62-002590c1f29c advisory. The command ctlpersistentreserveout allows the caller to specify an arbitrary size which will be passed...

Mimalloc Can Allocate Memory with Bad Alignment

This crate depended on a promise regarding alignments made by the author of the mimalloc allocator to avoid using aligned allocation functions where possible for performance reasons. Since then, the mimalloc allocator's logic changed, making it break this promise. This caused this crate to return...

CVE-2024-39281

The CVE-2024-39281 issue affects FreeBSD where the command ctl_persistent_reserve_out lets a caller specify an arbitrary size passed to the kernel memory allocator, enabling unbounded allocation in the ctl(4) CAM Target Layer and potentially causing a host DoS. The FreeBSD security advisory SA-24...

kernel: dax: Fix dax_mapping_release() use after free

A use-after-free vulnerability was found in the Linux kernel's device-dax subsystem during mapping object cleanup. When removing a dax region provider, the child daxmapping objects attempt to free their ID allocator after the parent devdax object has already been released. This causes idafree to...

kernel: zsmalloc: move LRU update from zs_map_object() to zs_malloc()

A flaw was found in the Linux kernel zsmalloc memory allocator. Under certain memory pressure and reclaim conditions, zsmalloc updated its LRU lists in an unsafe context, which could lead to list corruption due to a race between object mapping and allocation paths. A local user able to trigger...

kernel: bluetooth/hci: disallow setting handle bigger than HCI_CONN_HANDLE_MAX

A warning was observed in the Linux kernel in hciconndel caused by freeing handle that was not allocated using ida allocator. This is caused by handle bigger than HCICONNHANDLEMAX passed by hcilebigsyncestablishedevt, which makes code think it's unset connection...
