glibc qsort() Out-Of-Bounds Read / Write
Summary We discovered a memory corruption in the glibc’s qsort() function, due to a missing bounds check. To be vulnerable, a program must call qsort() with a nontransitive comparison function (a function cmp(int a, int b) that returns (a – b), for example) and with…
Heap-based buffer overflow in the glibc’s syslog ()
Summary -Heap-based buffer overflow in the glibc’s syslog () We discovered a heap-based buffer overflow in the GNU C Library’s __vsyslog_internal() function, which is called by both syslog() and vsyslog(). This vulnerability was introduced in glibc 2.37 (in August 2022) by the following commit: https://sourceware.org/git?p=glibc.git;a=commit;h=52a5be0df411ef3ff45c10c7c308cb92993d15b1…

Passive SSH Key Compromise via Lattices
ABSTRACTWe demonstrate that a passive network attacker can opportunistically obtain private RSA host keys from an SSH server that experiences a naturally arising fault during signature computation. In prior work, this was not believed to be possible for the SSH protocol because the signature included…
Terrapin Attack: Breaking SSH Channel IntegrityBy Sequence Number Manipulation
Abstract The SSH protocol provides secure access to network services, particularly remote terminal login and file transfer within organizational networks and to over 15 million servers on the open internet. SSH uses an authenticated key exchange to establish a secure channel between a client and…

Windows API Exploitation in Real World By Akash Sarode
Cyber Security in today’s world has become more challenging thantraditional days where we had Firewall and antivirus as our main defensesystems. Modern day adversary have got all the necessary resources – (Time,Team & Money) to execute their tasks of getting a victim compromised. Mostof the…
BLUFFS: Bluetooth Forward and Future Secrecy Attacks andDefenses
ABSTRACTBluetooth is a pervasive technology for wireless communication.Billions of devices use it in sensitive applications and to exchangeprivate data. The security of Bluetooth depends on the Bluetoothstandard and its two security mechanisms: pairing and session establishment. No prior work, including the standard itself, analyzed the…
Everlasting ROBOT: the Marvin Attack
Abstract. In this paper we show that Bleichenbacher-style attacks onRSA decryption are not only still possible, but also that vulnerable implementations are common. We have successfully attacked multiple implementations using only timing of decryption operation and shown thatmany others are vulnerable. To perform the attack…
