Redhat: >> Enterprise Linux Security Vulnerabilities
Buffer overflow in the polymorphic opcode support in the Regular Expression Engine (regcomp.c) in Perl 5.8 allows context-dependent attackers to execute arbitrary code by switching from byte to Unicode (UTF) characters in a regular expression.

Stack-based buffer overflow in the cons_options function in options.c in dhcpd in OpenBSD 4.0 through 4.2, and some other dhcpd implementations based on ISC dhcp-2, allows remote attackers to execute arbitrary code or cause a denial of service (daemon crash) via a DHCP request specifying a maximum message size smaller than the minimum IP MTU.

The NFS client implementation in the kernel in Red Hat Enterprise Linux (RHEL) 3, when a filesystem is mounted with the noacl option, checks permissions for the open system call via vfs_permission (mode bits) data rather than an NFS ACCESS call to the server, which allows local client processes to obtain a false success status from open calls that the server would deny, and possibly obtain sensitive information about file permissions on the server, as demonstrated in a root_squash environment. NOTE: it is uncertain whether any scenarios involving this issue cross privilege boundaries.

The ipv6_getsockopt_sticky function in the kernel in Red Hat Enterprise Linux (RHEL) Beta 5.1.0 allows local users to obtain sensitive information (kernel memory contents) via a negative value of the len parameter. NOTE: this issue has been disputed in a bug comment, stating that "len is ignored when copying header info to the user's buffer.

Off-by-one error in the QUtf8Decoder::toUnicode function in Trolltech Qt 3 allows context-dependent attackers to cause a denial of service (crash) via a crafted Unicode string that triggers a heap-based buffer overflow. NOTE: Qt 4 has the same error in the QUtf8Codec::convertToUnicode function, but it is not exploitable.

Unspecified vulnerability in the kernel in Red Hat Enterprise Linux (RHEL) 4 on the x86_64 platform allows local users to cause a denial of service (OOPS) via unspecified vectors related to the get_gate_vma function and the fuser command.

mm/mmap.c in the hugetlb kernel, when run on PowerPC systems, does not prevent stack expansion from entering into reserved kernel page memory, which allows local users to cause a denial of service (OOPS) via unspecified vectors.

Red Hat Enterprise Linux (RHEL) 5 ships the rpm for the Advanced Intrusion Detection Environment (AIDE) before 0.13.1 with a database that lacks checksum information, which allows context-dependent attackers to bypass file integrity checks and modify certain files.

xterm, including 192-7.el4 in Red Hat Enterprise Linux and 208-3.1 in Debian GNU/Linux, sets the wrong group ownership of tty devices, which allows local users to write data to other users' terminals.
