CVE-2019-17498 6 Debian, Fedoraproject, Libssh2 and 3 more 13 Debian Linux, Fedora, Libssh2 and 10 more 2026-10-14 8.1 High
In libssh2 v1.9.0 and earlier versions, the SSH_MSG_DISCONNECT logic in packet.c has an integer overflow in a bounds check, enabling an attacker to specify an arbitrary (out-of-bounds) offset for a subsequent memory read. A crafted SSH server may be able to disclose sensitive information or cause a denial of service condition on the client system when a user connects to the server.
CVE-2019-16905 3 Netapp, Openbsd, Siemens 7 Cloud Backup, Steelstore Cloud Integrated Storage, Openssh and 4 more 2026-10-14 7.8 High
OpenSSH 7.7 through 7.9 and 8.x before 8.1, when compiled with an experimental key type, has a pre-authentication integer overflow if a client or server is configured to use a crafted XMSS key. This leads to memory corruption and local code execution because of an error in the XMSS key parsing algorithm. NOTE: the XMSS implementation is considered experimental in all released OpenSSH versions, and there is no supported way to enable it when building portable OpenSSH.
CVE-2018-18928 1 Icu-project 1 International Components For Unicode 2026-10-14 N/A
International Components for Unicode (ICU) for C/C++ 63.1 has an integer overflow in number::impl::DecimalQuantity::toScientificString() in i18n/number_decimalquantity.cpp.
CVE-2017-15422 5 Canonical, Debian, Google and 2 more 8 Ubuntu Linux, Debian Linux, Chrome and 5 more 2026-10-14 N/A
Integer overflow in international date handling in International Components for Unicode (ICU) for C/C++ before 60.1, as used in V8 in Google Chrome prior to 63.0.3239.84 and other products, allowed a remote attacker to perform an out of bounds memory read via a crafted HTML page.
CVE-2026-88166 1 Microsoft 1 Sharepoint Server 2026-10-13 8.8 High
Integer overflow or wraparound in Microsoft Office SharePoint allows an authorized attacker to execute code over a network.
CVE-2023-51714 3 Debian, Qt, Redhat 3 Debian Linux, Qt, Enterprise Linux 2026-10-08 9.8 Critical
An issue was discovered in the HTTP2 implementation in Qt before 5.15.17, 6.x before 6.2.11, 6.3.x through 6.5.x before 6.5.4, and 6.6.x before 6.6.2. network/access/http2/hpacktable.cpp has an incorrect HPack integer overflow check.
CVE-2020-6073 2 Debian, Videolabs 2 Debian Linux, Libmicrodns 2026-10-08 7.5 High
An exploitable denial-of-service vulnerability exists in the TXT record-parsing functionality of Videolabs libmicrodns 0.1.0. When parsing the RDATA section in a TXT record in mDNS messages, multiple integer overflows can be triggered, leading to a denial of service. An attacker can send an mDNS message to trigger this vulnerability.
CVE-2019-5459 2 Opensuse, Videolan 4 Backports, Backports Sle, Leap and 1 more 2026-10-08 7.1 High
An Integer underflow in VLC Media Player versions < 3.0.7 leads to an out-of-band read.
CVE-2019-1551 8 Canonical, Debian, Fedoraproject and 5 more 11 Ubuntu Linux, Debian Linux, Fedora and 8 more 2026-10-08 5.3 Medium
There is an overflow bug in the x64_64 Montgomery squaring procedure used in exponentiation with 512-bit moduli. No EC algorithms are affected. Analysis suggests that attacks against 2-prime RSA1024, 3-prime RSA1536, and DSA1024 as a result of this defect would be very difficult to perform and are not believed likely. Attacks against DH512 are considered just feasible. However, for an attack the target would have to re-use the DH512 private key, which is not recommended anyway. Also applications directly using the low level API BN_mod_exp may be affected if they use BN_FLG_CONSTTIME. Fixed in OpenSSL 1.1.1e (Affected 1.1.1-1.1.1d). Fixed in OpenSSL 1.0.2u (Affected 1.0.2-1.0.2t).
CVE-2019-19721 1 Videolan 1 Vlc Media Player 2026-10-08 7.8 High
An off-by-one error in the DecodeBlock function in codec/sdl_image.c in VideoLAN VLC media player before 3.0.9 allows remote attackers to cause a denial of service (memory corruption) via a crafted image file. NOTE: this may be related to the SDL_Image product.
CVE-2019-13602 4 Canonical, Debian, Opensuse and 1 more 5 Ubuntu Linux, Debian Linux, Backports Sle and 2 more 2026-10-08 7.8 High
An Integer Underflow in MP4_EIA608_Convert() in modules/demux/mp4/mp4.c in VideoLAN VLC media player through 3.0.7.1 allows remote attackers to cause a denial of service (heap-based buffer overflow and crash) or possibly have unspecified other impact via a crafted .mp4 file.
CVE-2018-16301 1 Tcpdump 1 Tcpdump 2026-10-08 7.8 High
The command-line argument parser in tcpdump before 4.99.0 has a buffer overflow in tcpdump.c:read_infile(). To trigger this vulnerability the attacker needs to create a 4GB file on the local filesystem and to specify the file name as the value of the -F command-line argument of tcpdump.
CVE-2020-27171 4 Canonical, Debian, Fedoraproject and 1 more 4 Ubuntu Linux, Debian Linux, Fedora and 1 more 2026-10-08 6.0 Medium
An issue was discovered in the Linux kernel before 5.11.8. kernel/bpf/verifier.c has an off-by-one error (with a resultant integer underflow) affecting out-of-bounds speculation on pointer arithmetic, leading to side-channel attacks that defeat Spectre mitigations and obtain sensitive information from kernel memory, aka CID-10d2bb2e6b1d.
CVE-2020-14155 7 Apple, Gitlab, Netapp and 4 more 22 Macos, Gitlab, Active Iq Unified Manager and 19 more 2026-10-08 5.3 Medium
