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.
