Perl Unicode规则表达式缓冲区溢出漏洞

Perl是一款功能强大的编程语言。 Perl的规则表达式引擎存在一个缺陷，远程攻击者可以利用漏洞以Perl进程权限执行任意指令。 在处理Unicode规则表达式时存在一个缓冲区溢出，攻击者构建特殊的输入到规则表达式，可导致Perl不正确分配内存，导致以运行Perl进程的用户进程权限执行任意指令。 RedHat Enterprise Linux Desktop v.5 client RedHat Enterprise Linux WS 4 RedHat Enterprise Linux WS 3 RedHat Enterprise Linux v. 5 server RedHat...

Mandrake Linux Security Advisory : pcre (MDKSA-2007:212)

Multiple vulnerabilities were discovered by Tavis Ormandy and Will Drewry in the way that pcre handled certain malformed regular expressions. If an application linked against pcre, such as Konqueror, parses a malicious regular expression, it could lead to the execution of arbitrary code as the us...

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...
