[bounty] Jellyfin Exploits and TOCTOU Spellcasting
Another bug bounty podcast, another set of vulnerabilities. Starting off with a desktop info-disclosure in KeePass2 that discloses master passwords to attackers (with a high-level of access). A couple Jellyfin bugs resulting in an RCE chain, and a pretty classic crypto issue that allowed for renting luxury cars for extremely cheap.

[bounty] OverlayFS to Root and Parallels Desktop Escapes
More bug bounty style bugs, but you'd be forgiven reading that title thinking we had a low-level focus this episode. We got some awesome bugs this week though from tricking Dependabot and abusing placeholder values, an IIS auth bypass. Ending off with a kernel bug (OverlayFS) and a VM escape (Parallels Desktop)

[binary] TPMs and Baseband Bugs
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.
