04 Mar 2008 — A certain pseudo-random number generator (PRNG) algorithm that uses XOR and 3-bit random hops (aka "Algorithm X3"), as used in OpenBSD 2.8 through 4.2, allows remote attackers to guess sensitive values such as DNS transaction IDs by observing a sequence of previously generated values. NOTE: this issue can be leveraged for attacks such as DNS cache poisoning against OpenBSD's modification of BIND.

04 Mar 2008 — A certain pseudo-random number generator (PRNG) algorithm that uses XOR and 2-bit random hops (aka "Algorithm X2"), as used in OpenBSD 2.6 through 3.4, Mac OS X 10 through 10.5.1, FreeBSD 4.4 through 7.0, and DragonFlyBSD 1.0 through 1.10.1, allows remote attackers to guess sensitive values such as IP fragmentation IDs by observing a sequence of previously generated values. NOTE: this issue can be leveraged for attacks such as injection into TCP packets and OS fingerprinting. Cierto algoritmo generador de n... • http://seclists.org/bugtraq/2008/Feb/0052.html •

04 Mar 2008 — A certain pseudo-random number generator (PRNG) algorithm that uses ADD with 0 random hops (aka "Algorithm A0"), as used in OpenBSD 3.5 through 4.2 and NetBSD 1.6.2 through 4.0, allows remote attackers to guess sensitive values such as (1) DNS transaction IDs or (2) IP fragmentation IDs by observing a sequence of previously generated values.

15 Feb 2008 — The sendfile system call in FreeBSD 5.5 through 7.0 does not check the access flags of the file descriptor used for sending a file, which allows local users to read the contents of write-only files. La llamada al sistema de envío de ficheros (sendfile) en FreeBSD 5.5 hasta 7.0 no comprueba los indicadores de acceso del descriptor del fichero utilizado para enviar un archivo, esto permite a usuarios locales leer los contenidos de los ficheros de sólo-escritura. • http://secunia.com/advisories/28928 • CWE-264: Permissions, Privileges, and Access Controls •

16 Jan 2008 — The ptsname function in FreeBSD 6.0 through 7.0-PRERELEASE does not properly verify that a certain portion of a device name is associated with a pty of a user who is calling the pt_chown function, which might allow local users to read data from the pty from another user.

16 Jan 2008 — The script program in FreeBSD 5.0 through 7.0-PRERELEASE invokes openpty, which creates a pseudo-terminal with world-readable and world-writable permissions when it is not run as root, which allows local users to read data from the terminal of the user running script. La secuencia de comandos en FreeBSD 5.0 hasta 7.0-PRERELEASE llama a openpty, el cual crea un pseudo-terminal con permisos: lectura-todos y escritura-todos cuando no está funcionando como root, lo cual permite a usuarios locales leer datos des... • http://secunia.com/advisories/28498 • CWE-264: Permissions, Privileges, and Access Controls •

30 Nov 2007 — The "internal state tracking" code for the random and urandom devices in FreeBSD 5.5, 6.1 through 6.3, and 7.0 beta 4 allows local users to obtain portions of previously-accessed random values, which could be leveraged to bypass protection mechanisms that rely on secrecy of those values.

31 Dec 2005 — The securelevels implementation in FreeBSD 7.0 and earlier, OpenBSD up to 3.8, DragonFly up to 1.2, and Linux up to 2.6.15 allows root users to bypass immutable settings for files by mounting another filesystem that masks the immutable files while the system is running. • http://archives.neohapsis.com/archives/openbsd/2005-10/1523.html •
