[原文]fold_binary in fold-const.c in GNU Compiler Collection (gcc) 4.1 improperly handles pointer overflow when folding a certain expr comparison to a corresponding offset comparison in cases other than EQ_EXPR and NE_EXPR, which might introduce buffer overflow vulnerabilities into applications that could be exploited by context-dependent attackers.NOTE: the vendor states that the essence of the issue is "not correctly interpreting an offset to a pointer as a signed value."


[CNNVD]GNU Compiler Collection缓冲区溢出漏洞(CNNVD-200604-383)

        当将特定的expr比较合并入对应的offset比较而非EQ_EXPR 和NE_EXPR中时, GNU Compiler Collection (gcc) 4.1版本的fold-const.c中的fold_binary不能正确地处理指针溢出。这可能使得应用程序产生缓冲区溢出漏洞,导致上下文相关攻击者可以调用应用程序。
