One other possibility would be to make it optional at configure time, and to fail with a "sorry" diagnostic if the user uses the feature (or maybe uses "-dialect ibm") on a build of gcc cobol configured without libxml2. (I don't know if these are good ideas; just brainstorming). > Agreed needs documenting, missed that. Will fix.

Unsure; configure scripts aren't my strongest point (sorry). It's probably better to check and to fail gracefully and earlier at configure time if it's a hard dependency, rather than later with a possibly inscrutable #include or linkage error. > I would say we're limiting the user's security vulnerability as much > as possible: > More likely than not, libxml2 is being used somewhere in the firm > already. True, but a prudent sysadmin will want to keep track of all the different instances of libxml2 that they have in use at their site, and where, so that next time there's a CVE, they know the scope of their exposure, and what (if anything) needs patching. Hence it's good to be explicit up-front about dependencies. Sorry if it seems either like (a) I'm picking on you, or (b) that I'm stating the obvious; I think it's better to be clear about dependencies and what our security assumptions are. > COBOL syntax restricts the user's access to the library's API.

Yes, but one of the features you're using it for is... parsing XML :-) So I'm thinking that any vulnerability involving a maliciously-formed XML document (or DTD?) that allows an attacker to inject a behavior into libxml2 at XML parse time would become a security concern for libgcobol, and thus for the user's code. Ideally libgcobol would be dynamically linked against a "system copy" of libxml2, at which point the mitigation story for the user becomes: update the system copy of libxml2, and restart any processes transitively linked against it (thus including any linked against libgcobol, and thus presumably any binaries built against libgcobol). Perhaps you could have a libgcobol-xml target lib that contains just the xml parts, and only link the user's code to it if needed, but that may be overcomplicating things. > You tell me, but I guessed that libxml2 would be accepted more > readily than the Guile SSAX library. ;-) I'm very much inclined to agree. FWIW I'm guessing that the community would hesitate to accept libxml2 as a mandatory dependency for all of gcc, but it's probably a much easier sell if it's definitely dynamically linked and only needed if building with cobol enabled (especially if XML PARSE is built into the language, or an important dialect, and thus something that cobol users will expect to be available).
