RDMA/core: Prevent divide-by-zero error triggered by the user
The user_entry_size is supplied by the user and later used as a
denominator to calculate number of entries. The zero supplied by the user
will trigger the following divide-by-zero error:

| Microsoft AllJoyn API Denial of Service Vulnerability |
| A floating point exception (divide-by-zero) vulnerability was discovered in Artifex MuPDF 1.23.4 in function pnm_binary_read_image() of load-pnm.c when span equals zero. |
| TensorFlow is an open source platform for machine learning. If `Conv2D` is given empty `input` and the `filter` and `padding` sizes are valid, the output is all-zeros. This causes division-by-zero floating point exceptions that can be used to trigger a denial of service attack. We have patched the issue in GitHub commit 611d80db29dd7b0cfb755772c69d60ae5bca05f9. The fix will be included in TensorFlow 2.10.0. We will also cherrypick this commit on TensorFlow 2.9.1, TensorFlow 2.8.1, and TensorFlow 2.7.2, as these are also affected and still in supported range. There are no known workarounds for this issue. |
| Tensorflow is an Open Source Machine Learning Framework. An attacker can craft a TFLite model that would trigger a division by zero in `BiasAndClamp` implementation. There is no check that the `bias_size` is non zero. The fix will be included in TensorFlow 2.8.0. We will also cherrypick this commit on TensorFlow 2.7.1, TensorFlow 2.6.3, and TensorFlow 2.5.3, as these are also affected and still in supported range. |
| The printMP3Headers function in listmp3.c in Libming 0.4.7 allows remote attackers to cause a denial of service (divide-by-zero error and application crash) via a crafted mp3 file. |
| The _TIFFFax3fillruns function in libtiff before 4.0.6 allows remote attackers to cause a denial of service (divide-by-zero error and application crash) via a crafted Tiff image. |
| LibTIFF 4.0.7 allows remote attackers to cause a denial of service (divide-by-zero error and application crash) via a crafted TIFF image, related to libtiff/tif_ojpeg.c:816:8. |
| A denial of service vulnerability in libstagefright in Mediaserver could enable an attacker to use a specially crafted file to cause a device hang or reboot. This issue is rated as Moderate because it requires an uncommon device configuration. Product: Android. Versions: 4.4.4, 5.0.2, 5.1.1, 6.0, 6.0.1, 7.0, 7.1.1, 7.1.2. Android ID: A-35763994. |
| The insert_note_steps function in readmidi.c in TiMidity++ 2.14.0 allows remote attackers to cause a denial of service (divide-by-zero error and application crash) via a crafted mid file. NOTE: a crash might be relevant when using the --background option. |
| There is a division-by-zero vulnerability in LAME 3.99.5, caused by a malformed input file. |
| The tcp_disconnect function in net/ipv4/tcp.c in the Linux kernel before 4.12 allows local users to cause a denial of service (__tcp_select_window divide-by-zero error and system crash) by triggering a disconnect within a certain tcp_recvmsg code path. |
| In libsndfile 1.0.28, a divide-by-zero error exists in the function double64_init() in double64.c, which may lead to DoS when playing a crafted audio file. |
| The cirrus_do_copy function in hw/display/cirrus_vga.c in QEMU (aka Quick Emulator), when cirrus graphics mode is VGA, allows local guest OS privileged users to cause a denial of service (divide-by-zero error and QEMU process crash) via vectors involving blit pitch values. |
| game-music-emu before 0.6.1 allows local users to cause a denial of service (divide by zero and process crash). |
| The usbnet_generic_cdc_bind function in drivers/net/usb/cdc_ether.c in the Linux kernel through 4.13.11 allows local users to cause a denial of service (divide-by-zero error and system crash) or possibly have unspecified other impact via a crafted USB device. |
| In libsndfile 1.0.25 (fixed in 1.0.26), a divide-by-zero error exists in the function wav_w64_read_fmt_chunk() in wav_w64.c, which may lead to DoS when playing a crafted audio file. |
| The JPEGSetupEncode function in tiff_jpeg.c in LibTIFF 4.0.7 allows remote attackers to cause a denial of service (divide-by-zero error and application crash) via a crafted image. |
| The Microsoft Malware Protection Engine running on Microsoft Forefront and Microsoft Defender on Microsoft Windows Server 2008 SP2 and R2 SP1, Windows 7 SP1, Windows 8.1, Windows Server 2012 Gold and R2, Windows RT 8.1, Windows 10 Gold, 1511, 1607, and 1703, and Windows Server 2016, Microsoft Exchange Server 2013 and 2016, does not properly scan a specially crafted file leading to denial of service. aka "Microsoft Malware Protection Engine Denial of Service Vulnerability", a different vulnerability than CVE-2017-8536, CVE-2017-8537, CVE-2017-8539, and CVE-2017-8542. |
