Vulnerability from variot

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. Pure-FTPd is an FTP (File Transfer Protocol) server.

The 'init_aliases' function in the diraliases.c file in Pure-FTPd 1.0.49 has a security vulnerability. No detailed vulnerability details are provided at this time. - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - Gentoo Linux Security Advisory GLSA 202003-54
