Package: xterm Version: 231-1 Severity: important The TAB positions are stored in a bitmap array, which is defined in ptyx.h, line 1961. The size of this array is TAB_ARRAY_SIZE which is defined to be 10. Thus, Tabs array consists of ten 'unsigned int', tabs.c stores 32 positions in one position. This means that the all together 320 column position can be stored in the Tabs array.
However, if the xterm window has more than 320 columns overindexing can happen. This will lead to "Segmentation fault". Steps to reproduce: 1. open an xterm window 2. Copy, paste and execute the following escape sequence, which will set the font size to "unreadable" size: echo -e -n "\e]50;#1\0" 3. Copy, paste and execute the following escape sequence, which will resize the xterm window to the maximum possible size: echo -e "\e[9;1t" 4. Copy, paste and execute the following loop which will clear the TAB stops at each possible column: for i in $(seq 0 1024); do echo -e -n "\eHx"; done Actual result: "Segmentation fault" Expected result: the overindexing is not possible My screen resolution is 1024x768. -- System Information: Debian Release: lenny/sid APT prefers testing APT policy: (500, 'testing') Architecture: i386 (i686) Kernel: Linux 2.6.23 (PREEMPT) Locale: LANG=hu_HU, LC_CTYPE=hu_HU (charmap=ISO-8859-2) Shell: /bin/sh linked to /bin/bash Versions of packages xterm depends on: ii libc6 2.7-5 GNU C Library: Shared libraries ii libfontconfig1 2.5.0-2 generic font configuration library ii libice6 2:1.0.4-1 X11 Inter-Client Exchange library ii libncurses5 5.6+20071215-1 Shared libraries for terminal hand ii libsm6 2:1.0.3-1+b1 X11 Session Management library ii libx11-6 2:1.0.3-7 X11 client-side library ii libxaw7 2:1.0.4-1 X11 Athena Widget library ii libxext6 1:1.0.3-2 X11 miscellaneous extension librar ii libxft2 2.1.12-2 FreeType-based font drawing librar ii libxmu6 1:1.0.3-1 X11 miscellaneous utility library ii libxt6 1:1.0.5-3 X11 toolkit intrinsics library ii xbitmaps 1.0.1-2 Base X bitmaps Versions of packages xterm recommends: ii xutils 1:7.1.ds.3-1 X Window System utility programs -- no debconf information -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
