CVE-2026-8376— Perl 安全漏洞

Perl versions through 5.43.10 have a heap buffer overflow when compiling regular expressions with a repeated fixed string on 32-bit builds

Perl versions through 5.43.10 have a heap buffer overflow when compiling regular expressions with a repeated fixed string on 32-bit builds. Perl_study_chunk in regcomp_study.c checked the size of the joined substring buffer in characters rather than bytes. For a quantified fixed substring with a large minimum count, the byte length mincount * l could overflow SSize_t, producing an undersized SvGROW allocation; the subsequent copy writes past the end of the buffer. A caller that compiles an attacker-controlled regular expression on a 32-bit perl build triggers a heap buffer overflow at compile time.

整数溢出导致缓冲区溢出

Perl 安全漏洞

Perl是Perl社区的一款通用、解释型、动态的跨平台编程语言。 Perl 5.43.10及之前版本存在安全漏洞，该漏洞源于在32位构建中编译带有重复固定字符串的正则表达式时存在堆缓冲区溢出，可能导致编译时触发堆缓冲区溢出。
