CWE-416

It was found that the raw midi kernel driver does not protect against concurrent access which leads to a double realloc (double free) in snd_rawmidi_input_params() and snd_rawmidi_output_status() which are part of snd_rawmidi_ioctl() handler in rawmidi.c file. A malicious local attacker could possibly use this for privilege escalation.

A flaw was found in Linux kernel in the ext4 filesystem code. A use-after-free is possible in ext4_ext_remove_space() function when mounting and operating a crafted ext4 image.

Use-after-free in libtransmission/variant.c in Transmission before 3.00 allows remote attackers to cause a denial of service (crash) or possibly execute arbitrary code via a crafted torrent file.

In Long Range Zip (aka lrzip) 0.631, there is a use-after-free in the lzma_decompress_buf function of stream.c, which allows remote attackers to cause a denial of service (application crash) or possibly have unspecified other impact.

A use-after-free in Foxit Reader before 9.1 and PhantomPDF before 9.1 allows remote attackers to execute arbitrary code, aka iDefense ID V-jyb51g3mv9.
