WAF rule bypass in ModSecurity 3.0.0-3.0.15 on i386 architecture allows network-accessible attackers to evade rules that use the t:utf8toUnicode transformation, potentially permitting injection attacks or other malicious payloads to reach protected applications undetected. The root cause is CWE-467 - sizeof() applied to a char pointer in utf8_to_unicode.cc yields the pointer width (4 bytes on i386) rather than the unicode buffer length, corrupting transformation output. No public exploit code or active exploitation has been identified at time of analysis; the fix is available in v3.0.16.
The FPC (Flexible PIC Concentrator) of Juniper Networks Junos OS and Junos OS Evolved may restart after processing a specific IPv4 packet. Rated high severity (CVSS 7.5), this vulnerability is remotely exploitable, no authentication required, low attack complexity. No vendor patch available.
