Mozilla has various extra distrust/partial trust rules that are now coded in either NSS or Firefox itself. But we're not even using the distrust/partial trust information currently in certdata.txt. Other than what is in certdata.txt + code, there are also certificates that are distrusted by using OneCRL. I currently see no reason not to ship certdata.txt in all distributions. In any case, I think we should try to implement all the rules that Mozilla applies in all software that deals with certificate. And at least Mozilla is interested in that, and at least some of the OpenSSL people would also like to see OpenSSL have more checks than that currently happen. Kurt

Feel free to upload this. The usptream version in jessie and wheezy, so the patches should just apply. I only have a test for the 32 bit crashes. It would require to get the fuzzers working in the 1.0.1 version, which should be that hard. The other would be a cache timing attack, and I really have no good way to test that. I suggest you just upload it. Kurt

If I fix them for stable, I'll also fix them for oldstable. It's the same upstream version, the patches are identical. But I just have a new tarball, and diffstat shows: 187 files changed, 8094 insertions(+), 4295 deletions(-) And bitkeeper and the git don't have any of the patches.

OpenSSL for wheezy
Hi, The version in wheezy-security is currently 1.0.1e-2+deb7u21. Recently I've changed the jessie version from 1.0.1k to 1.0.1t without any problem. Supporting the 1.0.1e now requires a great deal of extra work because the patches just don't apply. If it's not because of the reformatting of the code, it's because various other bugs in the same code got fixed over the years. So I would like to just upload the 1.0.1u version to wheezy-security. If nobody complains that is what I will do. Kurt

First, the situation for wheezy and jessie should be identical. They have the same upstream source and should have the same patches for all security issues. The fix we use for CVE-2015-7979 is unrelated to the upstream fix, and so we're not affected by what the upstream patch broke. Kurt

I've complained about this mess many times, but it seems to be too complicated to make things simple. I suggest that you at least let me finish the patches I started on. > I assume that, since both wheezy and jessie share the same version > number, the same package can be uploaded for both? Or are there > significant changes between those two? Jessie and wheezy are the same upstream version, not much changed between the Debian version, so it's really trivial to get one done if the other is done. Squeeze had an slighty older version, but even that wasn't that much different. But they have been ignoring 4.2.6 for years, even before the 4.2.8 release, 4.2.8 was supposed to be release real soon now for years. > I wonder if it wouldn't be worth it to just ship 2.8 in wheezy/jessie > and get it over with.

The changes between 4.2.6 and 4.2.8 are years of work, caused lots of breakage (that we told years before the release), and I don't really trust 4.2.8 yet. Kurt

I need help getting them into jessie in the first place.

Those are the > issues currently pending: There are 22 open, some of which are marked as non-important. Of the new ones some should probably also be marked as such. I've spend several hours during the weekend going over commits in bitkeeper. But as ussual, it's all a big mess. I have 10 issues fixed in svn. I also have 7 files with the patches in as they apply to 4.2.8 version, but I didn't try to apply them to 4.2.6 version yet, so I have no idea what the state of those patches is.

So the effect of this seems to be that "ptr" which is a parameter to a function isn't use anymore as some pointer. But ptr isn't used anymore at this point, so seems that it doesn't have any effect.

So from the EVP_SignFinal manpage: | The number of bytes of data written (i.e. the length of the | signature) will be written to the integer at s, at most | EVP_PKEY_size(pkey) bytes will be written. That is, the signature can be shorter than the key, it depends on the signature scheme. And sign_siglen in both 4.2.6 and 4.2.8 is: sign_siglen = EVP_PKEY_size(sign_pkey); So maybe the variable name is a little misleading, it's the size of the key not the signature. Kurt

Your bug-2899.patch patch looks a little different. You have: @@ -2207,8 +2221,8 @@ crypto_bob( vp->sig = emalloc(sign_siglen); EVP_SignInit(&ctx, sign_digest); EVP_SignUpdate(&ctx, (u_char *)&vp->tstamp, 12); - EVP_SignUpdate(&ctx, vp->ptr, vallen); - if (EVP_SignFinal(&ctx, vp->sig, &vallen, sign_pkey)) + EVP_SignUpdate(&ctx, vp->ptr, len); + if (EVP_SignFinal(&ctx, vp->sig, &len, sign_pkey)) vp->siglen = htonl(sign_siglen); return (XEVNT_OK); } The patch from upstream and the one from redhat has: @@ -2214,9 +2228,9 @@ crypto_bob( vp->sig = emalloc(sign_siglen); EVP_SignInit(&ctx, sign_digest); EVP_SignUpdate(&ctx, (u_char *)&vp->tstamp, 12); - EVP_SignUpdate(&ctx, vp->ptr, vallen); - if (EVP_SignFinal(&ctx, vp->sig, &vallen, sign_pkey)) - vp->siglen = htonl(sign_siglen); + EVP_SignUpdate(&ctx, vp->ptr, len); + if (EVP_SignFinal(&ctx, vp->sig, &len, sign_pkey)) + vp->siglen = htonl(len); return (XEVNT_OK); } As in, the htonl() call changes sign_siglen to len. Your CVE-2015-7850 patch, in mvsyslog() calls vsnprintf() while mine calls mvsnprintf(). You somehow seems to have the patches applied, you have a .pc directory in it ... So you applied the following patches: CVE-2015-5300.patch bug-2899.patch (CVE-2015-7691, CVE-2015-7692, CVE-2015-7702) CVE-2015-7701.patch CVE-2015-7703.patch CVE-2015-7704.patch CVE-2015-7850.patch CVE-2015-7852.patch CVE-2015-7855.patch CVE-2015-7871.patch While I have addiotional patches for: CVE-2014-9750.patch (it was missing 1 patch while it was fixed it seems) ntp-4.2.6p5-cve-2015-5219.patch ntp-4.2.6p5-cve-2015-5195.patch ntp-4.2.6p5-cve-2015-5194.patch ntp-4.2.6p5-cve-2015-5146.patch CVE-2015-7705.patch CVE-2015-7851.patch CVE-2015-7853.patch Which leaves, which I think really don't affect 4.2.6: CVE-2015-7848 CVE-2015-7849 CVE-2015-7854 Should I just upload my patches?

Your patch probably makes sense and I should get that fixed in jessie and wheezy too. I'm just wondering why you didn't move the T_Pidfile like upstream did, that part seems to apply. (I have to go now, will look at it later again.) Kurt

I actually enabled this in 4.2.8p3+dfsg-1 for some reason. Kurt
