Redhat » Linux : Security Vulnerabilities, CVEs, CVSS score between 7 and 7.99

A Unix account has a default, null, blank, or missing password.

Qemu has a Buffer Overflow in pcnet_receive in hw/net/pcnet.c because an incorrect integer data type is used.

The Linux kernel, as used in Red Hat Enterprise Linux 7.2 and Red Hat Enterprise MRG 2 and when booted with UEFI Secure Boot enabled, allows local users to bypass intended Secure Boot restrictions and execute untrusted code by appending ACPI tables to the initrd.

The bluez_sock_create function in the Bluetooth stack for Linux kernel 2.4.6 through 2.4.30-rc1 and 2.6 through 2.6.11.5 allows local users to gain privileges via (1) socket or (2) socketpair call with a negative protocol value.

The patch for integer overflow vulnerabilities in Xpdf 2.0 and 3.0 (CVE-2004-0888) is incomplete for 64-bit architectures on certain Linux distributions such as Red Hat, which could leave Xpdf users exposed to the original vulnerabilities.

Integer overflow in the ubsec_keysetup function for Linux Broadcom 5820 cryptonet driver allows local users to cause a denial of service (crash) and possibly execute arbitrary code via a negative add_dsa_buf_bytes variable, which leads to a buffer overflow.

The do_change_cipher_spec function in OpenSSL 0.9.6c to 0.9.6k, and 0.9.7a to 0.9.7c, allows remote attackers to cause a denial of service (crash) via a crafted SSL/TLS handshake that triggers a null dereference.

tcpdump before 3.8.1 allows remote attackers to cause a denial of service (infinite loop) via certain ISAKMP packets, a different vulnerability than CVE-2004-0057.

Various PDF viewers including (1) Adobe Acrobat 5.06 and (2) Xpdf 1.01 allow remote attackers to execute arbitrary commands via shell metacharacters in an embedded hyperlink.

Konqueror Embedded and KDE 2.2.2 and earlier does not validate the Common Name (CN) field for X.509 Certificates, which could allow remote attackers to spoof certificates via a man-in-the-middle attack.

Unknown vulnerability in GNU Ghostscript before 7.07 allows attackers to execute arbitrary commands, even when -dSAFER is enabled, via a PostScript file that causes the commands to be executed from a malicious print job.

lv reads a .lv file from the current working directory, which allows local users to execute arbitrary commands as other lv users by placing malicious .lv files into other directories.

vsftpd FTP daemon in Red Hat Linux 9 is not compiled against TCP wrappers (tcp_wrappers) but is installed as a standalone service, which inadvertently prevents vsftpd from restricting access as intended.

uml_net in the kernel-utils package for Red Hat Linux 8.0 has incorrect setuid root privileges, which allows local users to modify network interfaces, e.g. by modifying ARP entries or placing interfaces into promiscuous mode.

The default configuration of the pam_xauth module forwards MIT-Magic-Cookies to new X sessions, which could allow local users to gain root privileges by stealing the cookies from a temporary .xauth file, which is created with the original user's credentials after root uses su.

Buffer overflow in KON kon2 0.3.9b and earlier allows local users to execute arbitrary code via a long -Coding command line argument.

dvips converter for Postscript files in the tetex package calls the system() function insecurely, which allows remote attackers to execute arbitrary commands via certain print jobs, possibly involving fonts.

Buffer overflow in newt.c of newt windowing library (libnewt) 0.50.33 and earlier may allow attackers to cause a denial of service or execute arbitrary code in setuid programs that use libnewt.

Squid 2.4 STABLE3 and earlier allows remote attackers to cause a denial of service (core dump) and possibly execute arbitrary code with an ftp:// URL with a larger number of special characters, which exceed the buffer when Squid URL-escapes the characters.

Squid 2.4 STABLE3 and earlier does not properly disable HTCP, even when "htcp_port 0" is specified in squid.conf, which could allow remote attackers to bypass intended access restrictions.

Buffer overflow in ncurses 5.0, and the ncurses4 compatibility package as used in Red Hat Linux, allows local users to gain privileges, related to "routines for moving the physical cursor and scrolling."

slapd in OpenLDAP 2.0 through 2.0.19 allows local users, and anonymous users before 2.0.8, to conduct a "replace" action on access controls without any values, which causes OpenLDAP to delete non-mandatory attributes that would otherwise be protected by ACLs.

Heap corruption vulnerability in the "at" program allows local users to execute arbitrary code via a malformed execution time, which causes at to free the same memory twice.

Format string vulnerability in stunnel before 3.22 when used in client mode for (1) smtp, (2) pop, or (3) nntp allows remote malicious servers to execute arbitrary code.

expect before 5.32 searches for its libraries in /var/tmp before other directories, which could allow local users to gain root privileges via a Trojan horse library that is accessed by mkpasswd.
