X.Org PCF font parser buffer overflow

Overview A vulnerability in the X.Org server could allow a remote attacker to execute arbitrary code on an affected system. Description The X.Org project provides an open source implementation of the X Window System. The server supports bitmapped fonts in various formats, including Portable...

Stack overflow

Stack-based buffer overflow in the commandExpandInterpret function in command.c in ppp aka user-ppp, as distributed in FreeBSD 6.3 and 7.0, OpenBSD 4.1 and 4.2, and the net/userppp package for NetBSD, allows local users to gain privileges via long commands containing "" characters...

CVE-2008-1215

Stack-based buffer overflow in the commandExpandInterpret function in command.c in ppp aka user-ppp, as distributed in FreeBSD 6.3 and 7.0, OpenBSD 4.1 and 4.2, and the net/userppp package for NetBSD, allows local users to gain privileges via long commands containing "" characters...

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...

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...

Design/Logic Flaw

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

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...

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...

CVE-2008-1148

CVE-2008-1148 concerns a flaw in a PRNG using ADD with 0 random hops (Algorithm A0) that affects OpenBSD 3.5–4.2 and NetBSD 1.6.2–4.0. Attackers can observe a sequence of previously generated values to guess sensitive identifiers such as DNS transaction IDs and IP fragmentation IDs, enabling pote...
