Package: kpdf
Version: 4:3.5.6-2
Severity: normal
I found that certain .pdf files can lead to memory exhaustion when
opened with kpdf, and sometimes in gv.
The attached pdf file was created by openoffice [1], and when opened
with xpdf it shows an empty page. However kpdf start using huge
amounts of memory when trying to open the page (2049M of virt memory,
and 1023M of RES memory).
The problem occured on Athlon64, with 2Gb of physical memory. If swap
is disactivated, kpdf makes the system freeze for a few minutes (till
the OOM killer starts killing some apps, but as usual it kills
everything [even X]).
If swap is available kpdf uses 2049MB of virt. memory, the system load
rises, and it uses approx. 900MB of swap.
I consider that for a .pdf of 1k, the amount of memory used by kpdf is
insane, and kpdf shouldn't blindly accept any size read from a pdf.
1]
The .pdf was created by selecting 3 charts in an OpenSpreadsheet
document, and using 'Export as PDF'. The charts weren't exported
correctly, but the bigger problem is that opening it in kpdf causes a
DoS. Tthe .pdf wasn't manipulated in any way, it is exactly as
openoffice created it.

Hi,
You filed the bug http://bugs.debian.org/421306
in the Debian BTS against the package kpdf.
Debian has switched to KDE 4 in unstable and kpdf
does not exist in KDE 4. Therefore, I am closing this bug as fixed
in *unstable*. The bug will remain open for stable since it is
shipping KDE 3.5.
For viewing PDF files in KDE 4 you can use okular.
Ana
