Redhat ≫ Enterprise Linux

yum-rhn-plugin in Red Hat Enterprise Linux (RHEL) 5 does not verify the SSL certificate for a file download from a Red Hat Network (RHN) server, which makes it easier for remote man-in-the-middle attackers to cause a denial of service (loss of update...

Race condition in the ptrace and utrace support in the Linux kernel 2.6.9 through 2.6.25, as used in Red Hat Enterprise Linux (RHEL) 4, allows local users to cause a denial of service (oops) via a long series of PTRACE_ATTACH ptrace calls to another ...

Double free vulnerability in the utrace support in the Linux kernel, probably 2.6.18, in Red Hat Enterprise Linux (RHEL) 5 and Fedora Core 6 (FC6) allows local users to cause a denial of service (oops), as demonstrated by a crash when running the GNU...

Untrusted search path vulnerability in a certain Red Hat build script for Standards Based Linux Instrumentation for Manageability (sblim) libraries before 1-13a.el4_6.1 in Red Hat Enterprise Linux (RHEL) 4, and before 1-31.el5_2.1 in RHEL 5, allows l...

The International Components for Unicode (ICU) library in Apple Mac OS X before 10.5.3, Red Hat Enterprise Linux 5, and other operating systems omits some invalid character sequences during conversion of some character encodings, which might allow re...

Buffer overflow in pattern.c in libxslt before 1.1.24 allows context-dependent attackers to cause a denial of service (crash) and possibly execute arbitrary code via an XSL style sheet file with a long XSLT "transformation match" condition that trigg...

Memory leak in a certain Red Hat patch, applied to vsftpd 2.0.5 on Red Hat Enterprise Linux (RHEL) 5 and Fedora 6 through 8, and on Foresight Linux and rPath appliances, allows remote attackers to cause a denial of service (memory consumption) via a ...

Linux kernel before 2.4.21 allows local users to cause a denial of service (kernel panic) via asynchronous input or output on a FIFO special file.

The IPsec implementation in Linux kernel before 2.6.25 allows remote routers to cause a denial of service (crash) via a fragmented ESP packet in which the first fragment does not contain the entire ESP header and IV.

Linux kernel 2.6.18, and possibly other versions, when running on AMD64 architectures, allows local users to cause a denial of service (crash) via certain ptrace calls.
