CVE-2002-1420

Integer signedness error in select on OpenBSD 3.1 and earlier allows local users to overwrite arbitrary kernel memory via a negative value for the size parameter, which satisfies the boundary check as a signed integer, but is later used as an unsigned integer during a data copying operation...

CVE-2002-1420

OpenBSD 3.1 and earlier are affected by a local privilege escalation due to an integer signedness error in select(2): a negative size value passes the boundary check as signed but is then used as unsigned during a data copy, allowing a local user to overwrite kernel memory. Impact: local code/ker...

CVE-2004-0114

The CVE-2004-0114 issue is a reference-count bug in SHMAT (System V Shared Memory) on FreeBSD/NetBSD/OpenBSD where shmat(2) increments the vm_object reference count and then calls vm_map_find; if vm_map_find fails, the reference count is not decremented. This can allow local attackers to gain rea...

Mandrake Linux Security Advisory : kernel (MDKSA-2004:087)

A race condition was discovered in the 64bit file offset handling by Paul Starzetz from iSEC. The file offset pointer fpos is changed during reading, writing, and seeking through a file in order to point to the current position of a file. The value conversion between both the 32bit and 64bit API ...

Linux Kernel: Multiple information leaks

Background The Linux kernel is responsible for managing the core aspects of a GNU/Linux system, providing an interface for core system applications as well as providing the essential structure and capability to access hardware that is needed for a running system. Description The Linux kernel allo...

Fedora Core 1 : kernel-2.4.22-1.2199.nptl (2004-251)

Paul Starzetz discovered flaws in the Linux kernel when handling file offset pointers. These consist of invalid conversions of 64 to 32-bit file offset pointers and possible race conditions. A local unprivileged user could make use of these flaws to access large portions of kernel memory. The...

Fedora Core 1 : kernel-2.4.22-1.2140.nptl (2003-047)

Various RTC drivers had the potential to leak small amounts of kernel memory to userspace through IOCTL's. The Common Vulnerabilities and Exposures project cve.mitre.org has assigned the name CVE-2003-0984 to this issue. Note that Tenable Network Security has extracted the preceding description...

CVE-2004-0602

The binary compatibility mode for FreeBSD 4.x and 5.x does not properly handle certain Linux system calls, which could allow local users to access kernel memory to gain privileges or cause a system panic...

CVE-2004-0602

The CVE-2004-0602 issue affects FreeBSD 4.x/5.x Linux binary compatibility mode. A programming error in handling certain Linux system calls can allow a local attacker to read/overwrite kernel memory, potentially gaining privileges or causing a system panic. Remediation in the connected docs inclu...
