Podcast Episodes (Page 12)

A few vulnerabilities from a TOCTOU to an arbitrary free, and some research into using data-flow in your fuzzing.

Some straight forward bugs this week with some interesting discussion around cryptographic protocols (VMWare Workspace), XSS in the Web3 world, and whether container escapes into a low-privileged VM matter. Along with a couple just note-worthy test-cases to keep in mind while bug hunting.

We are joined by Cts for a discussion about getting into vulnerability research and some thoughts about the higher-level bug hunting process, then a look at some black-box fuzzing of MS Defender for IoT and a FUSE use-after-free.

An intresting mix of issues from crypto (Psychic Signatures), to a bad vulnerability patching service (patching log4shell), and bad logic leading to authentication bypassing and leaking sensitive keys.

A massive 11,000 byte overflow in WatchGuard, some discussion about lock-related vulnerabilities and analysis, and a look at a ChakraCore exploit dealing with all the mitigations (ASLR, DEP, CFG, ACG,CIG)

Short episode this week, looking at some relatively simple vulnerabilities ranging XSS, to leaking internal service credentials in AWS Relational Database Service by disabling validiation.

We dive into an ASN.1 parsing bug impacting iOS, and a PHP use-after-free to bypass disabled functions, ending the week with a discussion about whether or not its too late to get into this area of security.

Quick bounty episode this week with some request smuggling, abusing a SSRF for client-sided impact, a weird oauth flow, and a desktop VPN client LPE.

More information about the FORCEDENTRY exploit chain, and some Linux exploitation with a couple netfilter bugs. Ending the episode with some discussion about exploiting blind kernel read primitives from Microsoft.

This week we have some fun with some bugs that really shouldn't have passed code-review, we of course talk about Spring4Shell/SpringShell and dive into the decade long history of that bug, and a bit of discussion about triaging more subtle bugs.
