DTLS is a datagram variant of TLS specified in RFC 4347 first supported in OpenSSL version 0.9.8. Note that the vulnerabilities do not affect SSL and TLS so only clients and servers explicitly using DTLS are affected. We believe this flaw will permit remote code execution. This vulnerability is tracked as CVE-2007-4995. Versions Affected - ----------------- All releases of 0.9.8 prior to 0.9.8f. Recommendation - -------------- Either a) Upgrade to the latest version of OpenSSL (0.9.8f) and rebuild all packages using OpenSSL for DTLS. or, b) Disable DTLS. Vulnerability B - --------------- Moritz Jodeit found an off-by-one error in SSL_get_shared_ciphers(), a function that should normally only be used for logging or debugging. The impact of this overflow is unclear. This vulnerability is tracked as CVE-2007-5135. Versions Affected - ----------------- All releases of 0.9.8 prior to 0.9.8f. All releases of 0.9.7 prior to 0.9.7m. (Note that versions prior to 0.9.8d and 0.9.7l actually had a worse problem in the same function). Recommendation - -------------- a) Don't use SSL_get_shared_ciphers(). OR b) Upgrade to 0.9.8f. - -- http://www.apache-ssl.org/ben.html http://www.links.org/ "There is no limit to what a man can do or how far he can go if he doesn't mind who gets the credit." - Robert Woodruff -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.2.5 (MingW32) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iQCVAwUBRw9VDBsIDEUnGa81AQEgFAP+MBSAb2CYGHXe0eicqsn3CRVE3R384PoC 01odYyJIdzjXrmgUxKZ0zaKst2Ud2BbNZff1WUDj3oymjc5wbylE2tQLK7KsetRv hpfFwKmwbiLmhYtei+CVXOQiO+inOPeS9KbDbOqE40wrD9yMShJfpJXE7OG/Mf5t 8+l8pKLYag0= =mVOD -----END PGP SIGNATURE-----
*** Bug 195674 has been marked as a duplicate of this bug. ***
CVE-2007-5135 was adressed with GLSA 200710-06. DTLS is used only for UDP mode, so I would rate this B1 as this isn't much used compared to classic TLS for TCP. Anyway, base-system: please provide updated ebuild.
0.9.8f is now in ... gave a quick test on x86/amd64/sparc/ppc/ppc64/ia64 and it seems to be ok ...
Arches, please test and mark stable dev-libs/openssl-0.9.8f. Target "-* alpha amd64 arm hppa ia64 m68k mips ppc ppc64 s390 sh sparc ~sparc-fbsd x86 ~x86-fbsd"
done on x86
Created attachment 133354 [details] openssl-0.9.8f.ebuild with padlock patch support
Created attachment 133358 [details, diff] padlock engine patch for 0.9.8f ebuild
Thanks, openssl-0.9.8f.ebuild works flawlessly, including padlock static loading patch. Tested on X86 with apache, mysql, postfix, courier, ssh...
Comment on attachment 133358 [details, diff] padlock engine patch for 0.9.8f ebuild stop posting this stuff as you were already told where to take it
alpha/ia64/sparc stable
ppc64 stable
Stable for HPPA.
dev-libs/openssl-0.9.8f USE="kerberos (sse2) test zlib -bindist -emacs -gmp" 1. Emerges on AMD64. 2. No collisions and passes all tests. 3. Works. Tested with openssh and can still login remotely with both password and keys.

(In reply to comment #17) > GLSA 200710-30 > As some of you noticed, the mail advisory included an error, vulnerable and unaffected versions were swapped, i.e. unaffected versions are of course >= 0.9.8f while vulnerable are < 0.9.8f, as the title says. Thanks for all of those who reported, you don't need to send me more e-mails about that now :)
