The remote host is affected by the vulnerability described in GLSA-200711-28 Perl: Buffer overflow Tavis Ormandy and Will Drewry Google Security Team discovered a heap-based buffer overflow in the Regular Expression engine regcomp.c that occurs when switching from byte to Unicode UTF-8 characters...

Perl: Buffer overflow

Background Perl is a stable, cross-platform programming language created by Larry Wall. Description Tavis Ormandy and Will Drewry Google Security Team discovered a heap-based buffer overflow in the Regular Expression engine regcomp.c that occurs when switching from byte to Unicode UTF-8 character...

CVE-2006-7230

CVE-2006-7230 concerns the PCRE library prior to 7.0, where memory sizing for a compiled regular expression can be miscalculated when the -x or -i UTF-8 options change within the pattern. This can allow a context-dependent attacker to cause a denial of service (PCRE or glibc crash). Affected prod...

CVE-2006-7230

Perl-Compatible Regular Expression PCRE library before 7.0 does not properly calculate the amount of memory needed for a compiled regular expression pattern when the 1 -x or 2 -i UTF-8 options change within the pattern, which allows context-dependent attackers to cause a denial of service PCRE or...

CVE-2006-7227

Integer overflow in Perl-Compatible Regular Expression PCRE library before 6.7 allows context-dependent attackers to execute arbitrary code via a regular expression containing a large number of named subpatterns namecount or long subpattern names maxnamesize, which triggers a buffer overflow. NOT...

CVE-2006-7228

Integer overflow in Perl-Compatible Regular Expression PCRE library before 6.7 might allow context-dependent attackers to execute arbitrary code via a regular expression that involves large 1 min, 2 max, or 3 duplength values that cause an incorrect length calculation and trigger a buffer overflo...

CVE-2006-7228

CVE-2006-7228 describes an integer overflow in the PCRE library before 6.7 that can be triggered by certain large min, max, or duplength values in a regex, leading to a context-dependent arbitrary code execution vulnerability. Public sources in the connected documents show this issue together wit...

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...
