The Crypt::Random::Source package before 0.13 for Perl has a fallback to the built-in rand() function, which is not a secure source of random bits.

GNU GRUB (aka GRUB2) through 2.12 does not use a constant-time algorithm for grub_crypto_memcmp and thus allows side-channel attacks.

GNU GRUB (aka GRUB2) through 2.12 has a heap-based buffer overflow in fs/hfs.c via crafted sblock data in an HFS filesystem.

A vulnerability classified as critical was found in 1000 Projects Attendance Tracking Management System 1.0. This vulnerability affects unknown code of the file /admin/attendance_action.php. The manipulation of the argument attendance_id leads to sql injection. The attack can be initiated remotely. The exploit has been disclosed to the public and may be used.
