Diving right into some binary exploitation issues this week. Starting wtih a look at a rare sort of curl vulnerability where a malicious server could compromise a curl user. Then we take a look at a pretty straight-forward type confusion in Windows kernel code, and an integer underflow in Safari with some questionable exploitation. Ending the episode with some thoughts on how impactful grsecurity's "constify" mitigation could be.
Some complex and confusing vulnerabilities as we talk about the recent WebP 0day and the complexities of huffman coding. A data-only exploit to escape a kCTF container, the glibc LPE LOONY_TUNABLES, and a Chrome TurboFan RCE.
A binary summer-recap episode, looking at some vulnerabilities and research put out over the summer. Talking about what TPM really offers when it comes to full-disk encryption, some thoughts on AI in the fuzzing loop. Then into some cool bugs, kicking off with some ARM Memory Tagging Extension vulnerabilities, a `-fstack-protector` implementation failure and bypass, and then a look at a Android exploit that was found in-the-wild.
This week we've got a handful of low-level vulns, VM-escape, Windows EoP, and a single IPv6 packet leading to a kernel panic/denial of service, and one higher-level issue with a bug chain in CS:GO.
This is our final episode until September 25th as we will be heading off on our regular summer break.
This week we we've got a neat little printer corruption, a probably unexploitable stockfish bug, though we speculate about exploitation a bit. Then into a VirtualBox escape bug, and an Andreno "vulnerability".
This week we go a bit deeper than normal and look at some low level TPM attacks to steal keys. We've got a cool attack that lets us leak a per-chip secret out of the TPM one byte at a time, and a post about reading Bitlocker's secret off the SPI bus. Then we talk about several Shannon baseband bugs disclosed by Google's Project Zero.
Not a lot of interesting binary exploitation topics for this week, we've got a DHCPv6 service vuln, and a fun idea to use a timing side-channel to improve exploit stability. Then we end with a discussion about Rust coming the Windows operating system, what Rust means for the future of exploit development and vulnerability research and the value of memory corruption in Windows.
This week's binary exploitation episode has some pretty solid bugs.A string escaping routine that goes out of bounds, a web-based information disclosure. And a couple kernel issues, one in the Windows registry, a logical bug leading to memory corruption, and an AppleSPU out of bounds access.
We start with a hardware/glitching attack against the Wii U, then lets talk about integer overflows. We've got three integer overflows this week that lead to buffer overflows in different ways.
Just a few bugs this week, a classic buffer overflow because of an unbounded copy in SNIProxy. mast1c0re Part 2 with a few more easy vulnerability but some more complex and difficult exploitation. And a Samsung NPU in-the-wild double free.
Its our 200th episode, and we've got some stats from our first 200 episodes. Then we talk some Pwn2Own policy changes, a couple memeable overflows, and some new anti-ROP mitigations on OpenBSD.
We've got a pretty nice root/super-use check bypass in XNU this week, and a sort of double fetch issue in Intel's SMM leading to a potential privilege escalation into the Management system. We've also got a few meme-able Shannon Baseband issues and some tough to exploit out of bound reads in MIT Kerberos V5.
Some simple, but interesting vulnerabilities. A use-after-free because of wrong operation ordering, an interesting type confusion, an integer underflow and some OOB access in TPM 2.0 reference code.
Just a couple issues this week, a cache coherency issue because the functions used to flush changes were not implemented on AARCH64. The second was using the "world's worst fuzzer" to find some bugs. Dumb fuzzer, but it worked.
