An arbitrary file upload vulnerability in the /v1/app/appendFileSync interface of Jan v0.4.12 allows attackers to execute arbitrary code via uploading a crafted file.

Jan v0.4.12 was discovered to contain an arbitrary file read vulnerability via the /v1/app/readFileSync interface.

An arbitrary file upload vulnerability in the /v1/app/writeFileSync interface of Jan v0.4.12 allows attackers to execute arbitrary code via uploading a crafted file.

os/linux/elf.rb in Homebrew brew before 4.2.20 uses ldd to load ELF files obtained from untrusted sources, which allows attackers to achieve code execution via an ELF file with a custom .interp section. NOTE: this code execution would occur during an un-sandboxed binary relocation phase, which occurs before a user would expect execution of downloaded package content. (237d1e783f7ee261beaba7d3f6bde22da7148b0a was the tested vulnerable version.)
