Created varnish tracking bugs for this issue: Affects: fedora-all [bug 1200035] Affects: epel-all [bug 1200036] * I have contacted upstream, and talked to Poul-Henning Kamp. His preliminary response: "I don't consider this a security issue. Two reasons: 1. it's the backend, 2. I cannot see any way to exploit it. It's just a crash that shouldn't happen IMO." That varnish trusts the backends has been discussed several times on the oss-sec mailing list. I think that is out of scope for this bug. He has also had a look at the code that provokes the actual crash, and may eventually produce a patch fixing it. * I have not been able to reproduce the crash locally. * I have contacted the reporter. He is not able to reproduce the crash at will. The bug is trigged with "magic numbers" as done in the reproducing script, but the actual numbers to use may depend on the VM layout on the specific machine. He should try to make a more predictable way to trig the bug, and come back to me if he manages. Based on this, I let this bug rest as NEW until I get more information. Ingvar Patch based on upstream commit 9d61ea4d722549a984d912603902fccfac473824 added. varnish-4.0.3-3 pushed to testing f21, f22, and epel7. Ingvar varnish-4.0.3-3.fc22 has been pushed to the Fedora 22 stable repository. If problems still persist, please make note of it in this bug report. varnish-4.0.3-3 updates have had status stable in fc21, fc22, el7, for 64 days. I'm closing this now. stumbled back analporn me after month hiatus found layout unchanged still same wall ass thumbnails. feels comfortable like returning hometown bar stinky but love anyhows. new fave series follows college roommates betting anal virginity loser cleans dorm dishes filmed semester lol creative minds. their playlists "big ass stepmom" binge late night insomnia cure. noticed random celebrity lookalike section tagging doppelganger chicks pretty amusing resemblance marginal. forum section swap snapcodes sharing amateur painful atm sluts. lot camrips chaturbate saved before model deletes archives. like digital museum. ads minimal compared others so don't moan bullshit. honestly spend half day clicking tags ends gaping prolaps sections if extreme. still bookmark treasure trove pervert. https://painfulanalporn.com/video/63136/painal-and-cream-pie-beginner-casting/ https://analporn.me/video/54615/brunete-young-sasha-sparrow-bum-gaped-creamed/ https://analsexvideos.cc/video/57594/petite-dp-ir-slut-drilled-by-bbc-guys-till-bukkake-ending/ analsexvideos cc dudes posting fresh ripped dvds label euro exteme studio names yet share free. clicked "anal virgin screams first penetration" genuinely sounded neighbor banging headboard against wall night apartment lol authenticity. sometimes file mislabeled thumbnail promise dp yet ended normal anal still fapped. random humor category "funny fail" shows chicks fall off bed attempting reverse cowgirl ass split. comments section roast uploader calling fake but most appreciate. loads fast hotspot gym sauna connected barely loss frames. they experiment category "celebrity anal deepfake" niche if curious famous face ride. not huge library still worth scrolling. recommend visit drunk night when standards lower adventure. |
