freerdp: FreeRDP global-buffer-overflow

A global buffer overflow flaw has been discovered in FreeRDP. This global-buffer-overflow was observed in FreeRDP's Base64 decoding path. The root cause appears to be implementation-defined char signedness: on Arm/AArch64 builds, plain char is treated as unsigned, so the guard c = 0 can be...

Unsoundness in anstream

When given a valid UTF8 string "ö\x1b😀", the function in crates/anstream/src/adapter/strip.rs will be confused. The UTF8 bytes are \xc3\xb6 then \x1b then \xf0\x9f\x98\x80. When looping over "non-printable bytes" \x1b\xf0 will be considered as some non-printable sequence. This will produce a brok...
