EUVD-2026-37782

libssh2 through 1.11.1, fixed in commit 1762685, contains a pre-authentication denial of service vulnerability in the SSHMSGEXTINFO handler in src/packet.c that allows a malicious SSH server to cause a client CPU exhaustion loop by sending a crafted extension count value. A malicious server can s...

An integer overflow in ext4fs_read_symlink in Das U-Boot before 2025.01-rc1 occurs for zalloc (adding one to an le32 variable) via a crafted ext4 filesystem with an inode size of 0xffffffff, resulting in a malloc of zero and resultant memory overwrite.

CVE-2024-51500: Improper Neutralization of Special Elements

Meshtastic firmware is a device firmware for the Meshtastic project. The Meshtastic firmware does not check for packets claiming to be from the special broadcast address 0xFFFFFFFF which could result in unexpected behavior and potential for DDoS attacks on the network. A malicious actor could cra...

CVE-2017-14470: Undefined Security Weakness

An exploitable access control vulnerability exists in the data, program, and function file permissions functionality of Allen Bradley Micrologix 1400 Series B FRN 21.2 and before. A specially crafted packet can cause a read or write operation resulting in disclosure of sensitive information,...

The vulnerability of the Oniguruma library, related to writing beyond the buffer boundaries on the stack, allows a hacker to cause a service failure.

The vulnerability of the Oniguruma library exists due to the improper handling of the code position 0xFFFFFFFF in the unicodeunfoldkey function during the compilation of regular expressions. As a result, when the nigencunicodegetcasefoldcodesbystr function is called, 4 bytes will be written at th...

ALPINE-CVE-2016-7167

Multiple integer overflows in the 1 curlescape, 2 curleasyescape, 3 curlunescape, and 4 curleasyunescape functions in libcurl before 7.50.3 allow attackers to have unspecified impact via a string of length 0xffffffff, which triggers a heap-based buffer overflow...

CVE-2014-9671

Off-by-one error in the pcfgetproperties function in pcf/pcfread.c in FreeType before 2.5.4 allows remote attackers to cause a denial of service NULL pointer dereference and application crash via a crafted PCF file with a 0xffffffff size value that is improperly incremented...

UBUNTU-CVE-2014-9671

Off-by-one error in the pcfgetproperties function in pcf/pcfread.c in FreeType before 2.5.4 allows remote attackers to cause a denial of service NULL pointer dereference and application crash via a crafted PCF file with a 0xffffffff size value that is improperly incremented...

Integer overflow

Integer overflow in the zipreadentry function in PHP 4 before 4.4.5 allows remote attackers to execute arbitrary code via a ZIP archive that contains an entry with a length value of 0xffffffff, which is incremented before use in an emalloc call, triggering a heap overflow...

PHP Zip_Entry_Read()整数溢出漏洞

PHP是一款广泛使用的WEB开发脚本语言。 PHP zipreadentry函数存在整数溢出问题，远程攻击者可利用此漏洞以应用程序权限执行任意指令。 zipreadentry函数没有对提供的长度参数进行任何检查，因此当增加一个字节到终止ASCIIZ字符时会在内存分配时出现整数溢出： buf = emalloclen + 1; ret = zzipreadentry-fp, buf, len; bufret = 0; 当提供的长度为0xffffffff，分配内存块会变成0字节大小。而之后会从ZIP档中读取4GB数据到内存块，造成覆盖分配的内存数据可能导致任意指令执行。 PHP PHP...
