Perl Unicode正则表达式堆溢出漏洞

BUGTRAQ ID: 26350 CVECAN ID: CVE-2007-5116 Perl是一种免费且功能强大的编程语言。 Perl的正则表达式引擎在计算处理正则表达式所需空间的方式存在错误，本地攻击者可能利用此漏洞提升权限。 如果用户所发送到正则表达式中包含有Unicode数据的话，就会导致运行时自动切换到Unicode字符主题，之后再传送的表达式就可能触发堆溢出，导致在用户机器上执行任意指令。 Larry Wall Perl 5.8.8 厂商补丁： Debian ------ Debian已经为此发布了一个安全公告（DSA-1400-1）以及相应补丁: DSA-1400-1：Ne...

CVE-2007-4768

CVE-2007-4768 describes a heap-based buffer overflow in the PCRE library (before 7.3) that can be triggered by a singleton Unicode sequence in a character class in a regex pattern, enabling context-dependent attackers to execute arbitrary code. Connected advisories (e.g., RHSA-2007-1126, Ubuntu U...

CVE-2007-1661

CVE-2007-1661 affects the Perl-Compatible Regular Expression (PCRE) library prior to 7.3, where backtracking can occur when matching certain input bytes against some patterns in non‑UTF‑8 mode, potentially exposing sensitive information or causing a denial of service (crash). The description expl...
