Certain BSD-based Telnet clients, including those used on Solaris and SuSE Linux, allow remote malicious Telnet servers to read sensitive environment variables via the NEW-ENVIRON option with a SEND ENV_USERVAR command. Included with many products Telnet Clients NEW-ENVIRON By command Telnet There is a problem that the environment variable information is illegally taken because the restriction of the environment variable sent to the server is inappropriate.By a third party IFRAME Tag and "TELNET://" Formal URI Etc., Web Malicious via page or email Telnet By enticing a target user to connect to a server, they may be able to obtain important information about the target system, such as the user's name, search path for executables, and locations of important data. still, Microsoft Windows 2000 Is not affected by this issue, Microsoft Windows Services for UNIX If you are using, you may be affected by this issue. Also some Linux Included with the distribution Kerberos Has been reported to be affected by this issue. Telnet clients provided by multiple vendors are prone to a remote information-disclosure vulnerability. Attackers can retrieve any information stored in the environment of clients using the affected telnet application. ---------------------------------------------------------------------- Bist Du interessiert an einem neuen Job in IT-Sicherheit?

Directory traversal vulnerability in gunzip -N in gzip 1.2.4 through 1.3.5 allows remote attackers to write to arbitrary directories via a .. (dot dot) in the original filename within a compressed file. ------------ This vulnerability information is a summary of multiple vulnerabilities released at the same time. Please note that the contents of vulnerability information other than the title are included. ------------ GNU zip (gzip) Is a utility that compresses and decompresses files. grep Run zgrep Or unzip the compressed file gunzip Each tool is packaged. Gzip 1.2.4 Previously, there were several security issues: 1) gzip 1.2.4 Included before zgrep There is a problem that does not properly sanitize arguments. (CAN-2005-0758) Details are currently unknown, but local attackers who exploit this issue zgrep An arbitrary command may be executed by passing an intentional file name to. 2) gzip 1.2.4 Previously, when decompressing a compressed file, there was a problem that caused a race condition between writing the decompressed file and changing permissions. (CAN-2005-0988) A local attacker who exploits this issue could alter the permissions of an arbitrary file by replacing the decompressed file with a hard link to the arbitrary file at a specific time. 3) gzip 1.2.4 Included before gunzip Is -N When decompressing a compressed file with a flag, there is a problem that the validity of the file name is not properly checked. (CAN-2005-1228) A remote attacker who exploits this issue ".." Send a compressed file that is a compressed file containing an intentional character string to the target user gzip Inducing a directory traversal attack by inducing unpacking with.Please refer to the “Overview” for the impact of this vulnerability. The gzip utility is prone to a directory-traversal vulnerability. The issue occurs when gunzip is invoked on a malicious archive using the '-N' option. An archive containing an absolute path for a filename that contains '/' characters can cause the file to be written using the absolute path contained in the filename. A remote attacker may leverage this issue using a malicious archive to corrupt arbitrary files with the privileges of the user that is running the vulnerable software. - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - Gentoo Linux Security Advisory GLSA 200505-05 - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - http://security.gentoo.org/ - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - Severity: Normal Title: gzip: Multiple vulnerabilities Date: May 09, 2005 Bugs: #89946, #90626 ID: 200505-05 - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - Synopsis ======== gzip contains multiple vulnerabilities potentially allowing an attacker to execute arbitrary commands.

Multiple TCP implementations with Protection Against Wrapped Sequence Numbers (PAWS) with the timestamps option enabled allow remote attackers to cause a denial of service (connection loss) via a spoofed packet with a large timer value, which causes the host to discard later packets because they appear to be too old. Certain TCP implementations may allow a remote attacker to arbitrarily modify host timestamp values, leading to a denial-of-service condition. TCP The implementation of the time stamp option is TCP A vulnerability exists that allows the internal timer on a connection to be changed to any value.the system TCP Connection reset and service disruption (DoS) It may be in a state. The Transmission Control Protocol (TCP) defined in RFC 793 allows reliable host-to-host transmission in a message exchange network. RFC 1323 introduces a number of technologies that enhance TCP performance, two of which are TCP timestamps and sequence number rollback protection (PAWS).  There are security holes in the PAWS technology of TCP RFC 1323. If TCP timestamps are enabled, both endpoints of the TCP connection use the internal clock to mark the TCP header with the timestamp value.  This vulnerability can occur if an attacker sends enough TCP PAWS packets to the vulnerable computer. An attacker can set the message timestamp to a large value. When the target machine processes this message, the internal timer will be updated to this value, which may cause all valid messages received afterwards to be discarded because these messages are considered too old or invalid. This technique may cause the target connection to deny service. ---------------------------------------------------------------------- Bist Du interessiert an einem neuen Job in IT-Sicherheit?

Cisco has acknowledged that various Cisco products are affected. The published Internet-Draft details three types of attacks, which utilize the following ICMP messages to cause a negative impact on TCP connections either terminating or originating from a vulnerable device. 1) ICMP "hard" error messages 2) ICMP "fragmentation needed and Don't Fragment (DF) bit set" messages (known as PMTUD attacks) 3) ICMP "source quench" messages These attacks can all be exploited to cause TCP connection resets, reduce the throughput in existing TCP connections, or consume large amounts of CPU and memory resources. NOTE: See the original advisory for a list of affected versions. SOLUTION: See patch matrix in vendor advisory for information about fixes

A vulnerability is present in the F5 BIG-IP user interface. This issue exists because the Configuration utility does not check the credentials for additional sessions from a user once they are logged in. Versions 9.0.2 through to 9.0.4 of BIG-IP are reported vulnerable to this issue.

AppleWebKit (WebCore and WebKit), as used in multiple products such as Safari 1.2 and OmniGroup OmniWeb 5.1, allows remote attackers to read arbitrary files via the XMLHttpRequest Javascript component, as demonstrated using automatically mounted disk images and file:// URLs. Web browsers based on AppleWebKit may allow remote web sites to reference content on the local filesystem. This may allow an attacker to execute script within the security context of the local machine. A remote code execution vulnerability affects Apple's WebCore Framework. This issue is due to a failure of the affected framework library to securely handle remote scripts. An attacker may leverage this issue to execute arbitrary code with the privileges of a user that activated the malicious remote script, facilitating unauthorized access and privilege escalation
