"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." Affected versions: 1.0.49, unclear if others affected. Patch: https://github.com/jedisct1/pure-ftpd/commit/8d0d42542e2cb7a56d645fbe4d0ef436e38bcefa
Second vulnerability (CVE-2020-9365): MITRE: https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2020-9365 Description: "An issue was discovered in Pure-FTPd 1.0.49. An out-of-bounds (OOB) read has been detected in the pure_strcmp function in utils.c." Same affected versions as above. Patch: https://github.com/jedisct1/pure-ftpd/commit/36c6d268cb190282a2c17106acfd31863121b58e
