Associated Vulnerability

Title:Pure-FTPd 缓冲区错误漏洞 (CVE-2020-9274)
Description:An issue was discovered in Pure-FTPd 1.0.49. An uninitialized pointer vulnerability has been detected in the diraliases linked list. When the *lookup_alias(const char alias) or print_aliases(void) function is called, they fail to correctly detect the end of the linked list and try to access a non-existent list member. This is related to init_aliases in diraliases.c.

Description

Pure-FTPd versions ≤ 1.0.49 (>= ~0.96) contain a vulnerability in the init_aliases() function within diraliases.c when processing aliases. This leads to access of an uninitialized pointer, which can cause a denial of service (DoS) condition.
