Description

GDALOpen() in 1.4 crashes when given an .aux file with an RRDNamesList() looking like this: 

    RRDNamesList(Eimg_RRDNamesList) @ 6133 + 229 @ 6261
    + algorithm = 
    +     string = `IMAGINE 2X2 Resampling'
    + nameList[0] = 
    +     string = `ntf8_1u_ui_atlanta.rrd(:Band_1:_ss_4_)'
    + nameList[1] = 
    +     string = `ntf8_1u_ui_atlanta.rrd(:Band_1:_ss_8_)'
    + nameList[2] = 
    +     string = `ntf8_1u_ui_atlanta.rrd(:Band_1:_ss_16_)'
    + nameList[3] = 
    +     string = `ntf8_1u_ui_atlanta.rrd(:Band_1:_ss_32_)'
    + nameList[4] = 
    + nameList[5] =

The problem does not occur in trunk.

Change History

  • status changed from new to closed.
  • cc set to dron, gaopeng.
  • resolution set to fixed.

It turns out the previously applied r11303 by Andrey ("Added number of buffer size checks to prevent overruns.") makes the HFA reading code quite a bit safer in the face of funky files.

Applying in 1.4 branch and 1.4-esri branch.

Note that this missed the 1.4.2 release.
