Talk:T1 Font Integer Overflow

Assignment

This article originally belonged to i0n1c's exploit (see "what links here"). Now also Saffron links here. Is this the same kernel exploit? --http 00:21, 7 July 2011 (UTC)

I'm not sure. If this was the original untether for i0n1c, then the information I put needs to be moved. I'm confused since there was no common name for the exploit he created. I saw it in Saffron and assumed it was the new one because of the confusion. Safest bet is to move it to a new page under DejaVu. --JakeAnthraX 00:39, 7 July 2011 (UTC)

This is indeed i0n1c's untethering exploit. I'll move this page (temporarily) to "DejaVu." --Dialexio 01:19, 7 July 2011 (UTC)

Ok, but there's still a lot wrong:

• Saffron links to Ndrv setspec() Integer Overflow
• Jailbreak page says Ndrv setspec() Integer Overflow is a userland exploit, while S5L8930 says it's a kernel exploit.
• Both jbm3 and i0n1c jailbreaks need each two exploits. Do they share the same kernel exploit?
• For the i0n1c jailbreak (not the exploits) there is no page yet.

I haven't understood everything yet, so I'll refrain from fixing it. --http 06:54, 7 July 2011 (UTC)

I fixed the first bullet. The terms "userland exploit" and "kernel exploit" seem to be synonymous. i0n1c never made a jailbreak; he just exploited the ndrv_setspec() Integer Overflow (and said exploit was used in PwnageTool/redsn0w/sn0wbreeze… NOT Saffron). I hope that clarifies everything more. --Dialexio 19:18, 7 July 2011 (UTC)

Ok. But we always talk about i0n1c's untether or so. This includes at least two exploits and is not mentioned sufficiently on the jb tools' pages. I suggest to create a new page, like for Saffron, where we can mention ASLR, credits, tools that use it, exploits used, heap feng shui, etc. For this exploit here, I assume this is the -1 encryption value (lenIV) bug (see http://t.co/q3KrcJA), right? This explains the Sandbox exit, but it does not explain circumvention of ASLR and priviledge escalation.-- http 10:04, 9 July 2011 (UTC)

Another related issue: On Apple KB site they list three vulnerabilities related to Saffron. --http 02:42, 16 July 2011 (MDT)
