Version 1.9. of the software package was launched on January 19. On Thursday, Google Job Zero researcher Tavis Ormandy publicly disclosed the existence of a “heap buffer overflow in libgcrypt thanks to an incorrect assumption in the block buffer management code.”

“Just decrypting some info can overflow a heap buffer with attacker-controlled information, no verification or signature is validated right before the vulnerability occurs,” Ormandy reported. “I imagine this is quickly exploitable.”

The researcher handed on his conclusions to libgcrypt builders. As before long as the report was been given, the workforce revealed an instant discover for buyers, “[Announce] [urgent] Quit utilizing Libgcrypt 1.9.!”.
