CVE-2008-1215

CVE-2008-1215 is a stack-based buffer overflow in the command_Expand_Interpret function of command.c used by ppp (user-ppp) in FreeBSD 6.3/7.0, OpenBSD 4.1/4.2, and NetBSD net/userppp. The overflow can let local users gain privileges via long commands containing ~ characters. CVSS2 metrics indica...

Design/Logic Flaw

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 issu...

Code injection

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 I...

CVE-2008-1148

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...

CVE-2008-1146

CVE-2008-1146 affects OpenBSD 2.8–4.2 where a PRNG using XOR with 3-bit hops (Algorithm X3) enables remote attackers to infer DNS transaction IDs from prior outputs, potentially enabling DNS cache poisoning on OpenBSD’s BIND modification. Impact per NVD indicates partial confidentiality, partial ...

CVE-2008-1147

CVE-2008-1147 describes a weakness in a PRNG that uses XOR and 2-bit random hops (Algorithm X2) used in OpenBSD 2.6–3.4, macOS 10–10.5.1, FreeBSD 4.4–7.0, and DragonFlyBSD 1.0–1.10.1. The vulnerability allows remote attackers to infer sensitive values such as IP fragmentation IDs by observing a s...
