A heap-based Buffer Overflow vulnerability exists in FFmpeg 4.2 at libavfilter/vf_colorconstancy.c: in slice_get_derivative, which crossfade_samples_fltp, which might lead to memory corruption and other potential consequences.

An issue was discovered in Squid before 4.15 and 5.x before 5.0.6. Due to an input-validation bug, it is vulnerable to a Denial of Service attack (against all clients using the proxy). A client sends an HTTP Range request to trigger this.

An issue was discovered in Squid before 4.15 and 5.x before 5.0.6. Due to a memory-management bug, it is vulnerable to a Denial of Service attack (against all clients using the proxy) via HTTP Range request processing.

An issue was discovered in Squid 4.x before 4.15 and 5.x before 5.0.6. If a remote server sends a certain response header over HTTP or HTTPS, there is a denial of service. This header can plausibly occur in benign network traffic.

An issue was discovered in Squid before 4.15 and 5.x before 5.0.6. Due to incorrect parser validation, it allows a Denial of Service attack against the Cache Manager API. This allows a trusted client to trigger memory leaks that. over time, lead to a Denial of Service via an unspecified short query string. This attack is limited to clients with Cache Manager API access privilege.

An issue was discovered in Squid before 4.15 and 5.x before 5.0.6. Due to a buffer-management bug, it allows a denial of service. When resolving a request with the urn: scheme, the parser leaks a small amount of memory. However, there is an unspecified attack methodology that can easily trigger a large amount of memory consumption.

A possible information disclosure / unintended method execution vulnerability in Action Pack >= 2.0.0 when using the `redirect_to` or `polymorphic_url`helper with untrusted user input.

A flaw was found in the USB redirector device (usb-redir) of QEMU. Small USB packets are combined into a single, large transfer request, to reduce the overhead and improve performance. The combined size of the bulk transfer is used to dynamically allocate a variable length array (VLA) on the stack without proper validation. Since the total size is not bounded, a malicious guest could use this flaw to influence the array length and cause the QEMU process to perform an excessive allocation on the stack, resulting in a denial of service.

A NULL pointer dereference flaw was found in the floppy disk emulator of QEMU. This issue occurs while processing read/write ioport commands if the selected floppy drive is not initialized with a block device. This flaw allows a privileged guest user to crash the QEMU process on the host, resulting in a denial of service. The highest threat from this vulnerability is to system availability.

Buffer Overflow vulnerability exists in FFmpeg 4.2 in filter_vertically_8 at libavfilter/vf_avgblur.c, which could cause a remote Denial of Service.

Buffer Overflow vulnerability exists in FFmpeg 4.2 in the config_input function at libavfilter/af_tremolo.c, which could let a remote malicious user cause a Denial of Service.

Buffer Overflow vulnerability in FFmpeg 4.2 at filter_edges function in libavfilter/vf_yadif.c, which could let a remote malicious user cause a Denial of Service.

Buffer Overflow vulnerability in FFmpeg 4.2 in the build_diff_map function in libavfilter/vf_fieldmatch.c, which could let a remote malicious user cause a Denial of Service.

Buffer Overflow vulnerability in FFmpeg 4.2 at convolution_y_10bit in libavfilter/vf_vmafmotion.c, which could let a remote malicious user cause a Denial of Service.

Buffer Overflow vulnerability in FFmpeg 4.2 in mov_write_video_tag due to the out of bounds in libavformat/movenc.c, which could let a remote malicious user obtain sensitive information, cause a Denial of Service, or execute arbitrary code.

An issue was discovered in management/commands/hyperkitty_import.py in HyperKitty through 1.3.4. When importing a private mailing list's archives, these archives are publicly visible for the duration of the import. For example, sensitive information might be available on the web for an hour during a large migration from Mailman 2 to Mailman 3.

A flaw was found in the JFS filesystem code in the Linux Kernel which allows a local attacker with the ability to set extended attributes to panic the system, causing memory corruption or escalating privileges. The highest threat from this vulnerability is to confidentiality, integrity, as well as system availability.

The mq_notify function in the GNU C Library (aka glibc) versions 2.32 and 2.33 has a use-after-free. It may use the notification thread attributes object (passed through its struct sigevent parameter) after it has been freed by the caller, leading to a denial of service (application crash) or possibly unspecified other impact.

FFmpeg 4.2 is affected by a Divide By Zero issue via libavcodec/aaccoder, which allows a remote malicious user to cause a Denial of Service

FFmpeg 4.2 is affected by a Divide By Zero issue via libavcodec/aacpsy.c, which allows a remote malicious user to cause a Denial of Service.
