CVE-2004-1307

TITLE

Apple Terminal fails to properly sanitize input for "x-man-page" URI

DESCRIPTION

Integer overflow in the TIFFFetchStripThing function in tif_dirread.c for libtiff 3.6.1 allows remote attackers to execute arbitrary code via a TIFF file with the STRIPOFFSETS flag and a large number of strips, which causes a zero byte buffer to be allocated and leads to a heap-based buffer overflow. Apple Terminal on Mac OS X fails to sanitize x-man-page URIs, allowing an attacker to execute arbitrary commands. LibTIFF Library TIFFFetchStripThing() Perform memory allocation in functions CheckMalloc() An integer overflow vulnerability exists due to a flaw in the validation of the value passed to the function.LibTIFF Arbitrary code may be executed with the execution authority of the application that uses the library. ---------------------------------------------------------------------- Want a new IT Security job?

NOTE: htdigest is by default only locally accessible and not setuid / setgid. 2) An integer overflow error in the AppKit component when processing TIFF files can be exploited by malicious people to compromise a user's system. For more information: SA13607 3) An error in the AppKit component when parsing certain TIFF images can result in an invalid call to the "NXSeek()" function, which will crash an affected Cocoa application. 4) An error within the handling of AppleScript can be exploited to display code to a user that is different than the code, which will actually run. 5) An error in the Bluetooth support may cause Bluetooth-enabled systems to share files via the Bluetooth file exchange service without notifying the user properly. 6) An input validation error can be exploited to access arbitrary files on a Bluetooth-enabled system using directory traversal attacks via the Bluetooth file and object exchange services. 7) The chfn, chpass, and chsh utilities invoke certain external helper programs insecurely, which can be exploited by malicious, local users to gain escalated privileges. 8) A vulnerability in Finder can be exploited by malicious, local users to perform certain actions on a vulnerable system with escalated privileges due to insecure creation of ".DS_Store" files. For more information: SA14188 9) A boundary error within the Foundation framework when handling environment variables can be exploited to cause a buffer overflow and may allow execution of arbitrary code. 10) An error in Help Viewer can be exploited to run JavaScript without the normally imposed security restrictions. 11) A security issue in the LDAP functionality may under certain circumstances result in passwords initially being stored in plain text. 12) Errors within the parsing of XPM files can potentially be exploited by malicious people to compromise a vulnerable system. For more information: SA12549 13) An error in lukemftpd can be exploited by malicious users to bypass chroot restrictions. In order to restrict users to their home directory, both their full name and short name must be listed in the "/etc/ftpchroot" file. However, the problem is that users can change their full name and thereby bypass this restriction. 14) A boundary error in the Netinfo Setup Tool (NeST) when processing input passed to the "-target" command line parameter can be exploited by malicious, local users to cause a buffer overflow and execute arbitrary code with escalated privileges on a vulnerable system. 15) When enabling the HTTP proxy service in Server Admin, it is by default possible for everyone (including users on the Internet) to use the proxy service. 16) A vulnerability in sudo within the environment clearing can be exploited by malicious, local users to gain escalated privileges. For more information: SA13199 17) An error in the Terminal utility can be exploited to inject data via malicious input containing escape sequences in window titles. 18) An error in the Terminal utility can be exploited to inject commands into a user's Terminal session via malicious input containing escape characters in x-man-path URIs. 19) A boundary error in vpnd can be exploited by malicious, local users to cause a buffer overflow and execute arbitrary code with escalated privileges on systems configured as a VPN server.
