CVE-2025-30356 1 Nasa 1 Cryptolib 2025-04-29 9.8 Critical
CryptoLib provides a software-only solution using the CCSDS Space Data Link Security Protocol - Extended Procedures (SDLS-EP) to secure communications between a spacecraft running the core Flight System (cFS) and a ground station. In 1.3.3 and earlier, a heap buffer overflow vulnerability persists in the Crypto_TC_ApplySecurity function due to an incomplete validation check on the fl (frame length) field. Although CVE-2025-29912 addressed an underflow issue involving fl, the patch fails to fully prevent unsafe calculations. As a result, an attacker can still craft malicious frames that cause a negative tf_payload_len, which is then interpreted as a large unsigned value, leading to a heap buffer overflow in a memcpy call.
CVE-2022-37301 1 Schneider-electric 96 Modicon M340 Bmx P34-2010, Modicon M340 Bmx P34-2010 Firmware, Modicon M340 Bmx P34-2030 and 93 more 2025-04-28 7.5 High

Affected products: Modicon M340 CPU (part numbers BMXP34*)(V3.40 and prior), Modicon M580 CPU (part numbers BMEP* and BMEH*)(V3.22 and prior), Legacy Modicon Quantum/Premium(All Versions), Modicon Momentum MDI (171CBU*)(All Versions), Modicon MC80 (BMKC80)(V1.7 and prior)
CVE-2022-21685 1 Parity 1 Frontier 2025-04-23 6.5 Medium
Frontier is Substrate's Ethereum compatibility layer. Prior to commit number `8a93fdc6c9f4eb1d2f2a11b7ff1d12d70bf5a664`, a bug in Frontier's MODEXP precompile implementation can cause an integer underflow in certain conditions. This will cause a node crash for debug builds. For release builds (and production WebAssembly binaries), the impact is limited as it can only cause a normal EVM out-of-gas. Users who do not use MODEXP precompile in their runtime are not impacted. A patch is available in pull request #549.
CVE-2022-23613 2 Fedoraproject, Neutrinolabs 2 Fedora, Xrdp 2025-04-23 7.8 High
xrdp is an open source remote desktop protocol (RDP) server. In affected versions an integer underflow leading to a heap overflow in the sesman server allows any unauthenticated attacker which is able to locally access a sesman server to execute code as root. This vulnerability has been patched in version 0.9.18.1 and above. Users are advised to upgrade. There are no known workarounds.
CVE-2022-20483 1 Google 1 Android 2025-04-22 7.5 High
In several functions that parse avrc response in avrc_pars_ct.cc and related files, there are possible out of bounds reads due to integer overflows. This could lead to remote information disclosure with no additional execution privileges needed. User interaction is not needed for exploitation.Product: AndroidVersions: Android-10 Android-11 Android-12 Android-12L Android-13Android ID: A-242459126
CVE-2022-39343 1 Microsoft 1 Azure Rtos Filex 2025-04-22 5.6 Medium
Azure RTOS FileX is a FAT-compatible file system that’s fully integrated with Azure RTOS ThreadX. In versions before 6.2.0, the Fault Tolerant feature of Azure RTOS FileX includes integer under and overflows which may be exploited to achieve buffer overflow and modify memory contents. When a valid log file with correct ID and checksum is detected by the `_fx_fault_tolerant_enable` function an attempt to recover the previous failed write operation is taken by call of `_fx_fault_tolerant_apply_logs`. This function iterates through the log entries and performs required recovery operations. When properly crafted a log including entries of type `FX_FAULT_TOLERANT_DIR_LOG_TYPE` may be utilized to introduce unexpected behavior. This issue has been patched in version 6.2.0. A workaround to fix line 218 in fx_fault_tolerant_apply_logs.c is documented in the GHSA.
CVE-2024-56375 1 Nicmx 1 Fort Validator 2025-04-22 7.5 High
An integer underflow was discovered in Fort 1.6.3 and 1.6.4 before 1.6.5. A malicious RPKI repository that descends from a (trusted) Trust Anchor can serve (via rsync or RRDP) a Manifest RPKI object containing an empty fileList. Fort dereferences (and, shortly afterwards, writes to) this array during a shuffle attempt, before the validation that would normally reject it when empty. This out-of-bounds access is caused by an integer underflow that causes the surrounding loop to iterate infinitely. Because the product is permanently stuck attempting to overshuffle an array that doesn't actually exist, a crash is nearly guaranteed.
CVE-2016-10268 1 Libtiff 1 Libtiff 2025-04-20 N/A
tools/tiffcp.c in LibTIFF 4.0.7 allows remote attackers to cause a denial of service (integer underflow and heap-based buffer under-read) or possibly have unspecified other impact via a crafted TIFF image, related to "READ of size 78490" and libtiff/tif_unix.c:115:23.
CVE-2017-13666 1 Multicorewareinc 1 X265 2025-04-20 N/A
An integer underflow vulnerability exists in pixel-a.asm, the x86 assembly code for planeClipAndMax() in MulticoreWare x265 through 2.5, as used in libbpg and other products. A small height value can cause an integer underflow, which leads to a crash. This is a different vulnerability than CVE-2017-8906.
CVE-2015-2311 1 Capnproto 1 Capnproto 2025-04-20 N/A
Integer underflow in Sandstorm Cap'n Proto before 0.4.1.1 and 0.5.x before 0.5.1.1 might allow remote peers to cause a denial of service or possibly obtain sensitive information from memory or execute arbitrary code via a crafted message.
CVE-2017-14997 2 Debian, Graphicsmagick 2 Debian Linux, Graphicsmagick 2025-04-20 N/A
GraphicsMagick 1.3.26 allows remote attackers to cause a denial of service (excessive memory allocation) because of an integer underflow in ReadPICTImage in coders/pict.c.
CVE-2017-9214 3 Debian, Openvswitch, Redhat 6 Debian Linux, Openvswitch, Enterprise Linux and 3 more 2025-04-20 9.8 Critical
In Open vSwitch (OvS) 2.7.0, while parsing an OFPT_QUEUE_GET_CONFIG_REPLY type OFP 1.0 message, there is a buffer over-read that is caused by an unsigned integer underflow in the function `ofputil_pull_queue_get_config_reply10` in `lib/ofp-util.c`.

An integer underflow vulnerability exists in pixel-a.asm, the x86 assembly code for planeClipAndMax() in MulticoreWare x265 through 2.4, as used by the x265_encoder_encode dependency in libbpg and other products. A small picture can cause an integer underflow, which leads to a Denial of Service in the process of encoding.
CVE-2017-14796 1 Libbpg Project 1 Libbpg 2025-04-20 N/A
The hevc_write_frame function in libbpg.c in libbpg 0.9.7 allows remote attackers to cause a denial of service (integer underflow and application crash) or possibly have unspecified other impact via a crafted BPG file, related to improper interaction with copy_CTB_to_hv in hevc_filter.c in libavcodec in FFmpeg and sao_filter_CTB in hevc_filter.c in libavcodec in FFmpeg.
CVE-2016-10166 2 Libgd, Redhat 2 Libgd, Rhel Software Collections 2025-04-20 N/A
