Bug#507591: maradns: Segmentation fault when using a config file with syntax error
Upstream here. This issue was never present in MaraDNS 1.2, and has been fixed in MaraDNS 1.3.07.10 and MaraDNS 1.4.03. If Debian versions of MaraDNS still have this bug, they need to incorporate my fix, or, better yet, upgrade to 1.3.07.10 or 1.4.03. - Sam Note: I do not answer MaraDNS (including Deadwood) support requests sent by private email without being compensated for my time. A MaraDNS support request is any and all discussion you may wish to have about MaraDNS in private email; if you want to email me to talk about MaraDNS then, yes, that is a support request. I will discuss rates if you want this kind of support. Thank you for your understanding. MaraDNS security vulnerability reports, however, will be dealt with without charge and kept confidential. If you don't know what Bugtraq is, then, no, your email is not a security report. It is not a security report unless you've done due diligence to determine how the security bug you think you found can reasonably be exploited. -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of unsubscribe.

Bug#507591: maradns: Segmentation fault when using a config file with syntax error
Package: maradns Version: 1.3.07.09-2 Severity: normal Hi! While I know that the syntax error should be fixed in the config file, maradns shouldn't segfault when reading a bad config file. I don't know how helpful it is, but running it (compiled with noopt and nostrip) with gdb I get this: Starting program: /usr/sbin/maradns -f /etc/maradns/mararc [Thread debugging using libthread_db enabled] [New Thread 0xb7e176b0 (LWP 10279)] Program received signal SIGSEGV, Segmentation fault.
