PHP "crypt()" MD5 Salt安全漏洞

PHP是流行的脚本语言环境。 PHP在"crypt"函数的实现上存在安全漏洞，远程攻击者可利用此漏洞绕过某些安全限制。 此漏洞源于"crypt"函数在生成有salt的MD5哈希时，仅返回salt PHP 5.3.x 厂商补丁： PHP --- 目前厂商已经发布了升级补丁以修复这个安全问题，请到厂商的主页下载： http://www.php.net...

CVE-2007-2844

PHP 4.x and 5.x before 5.2.1, when running on multi-threaded systems, does not ensure thread safety for libc crypt function calls using protection schemes such as a mutex, which creates race conditions that allow remote attackers to overwrite internal program memory and gain system access...

CVE-2001-0967

Knox Arkeia server (notably version 4.2) uses a constant salt when hashing passwords via crypt(), enabling easier brute‑force guessing. The root cause is the non‑unique salt value in password encryption, which compromises password strength. The PT-2001-2119 advisory aligns with this, describing t...

qnx crypt comprimised

the crypt function for qnx turned out to a bit mixer, not a hash function. It's now possible to extract plaintext from the hashes. On a related note, all IOpeners running qnx use the same root password. Telnetd is running, and allows remote login as root. This is a huge security hole, as you can...
