Bug 160795

Summary:	media-libs/smpeg-0.4.4-r8 Segfault caused by missing initialisation
Product:	Gentoo Linux	Reporter:	Vincent Le Ligeour <gentoo>
Component:	[OLD] Library	Assignee:	Gentoo Games <games>
Status:	RESOLVED FIXED
Severity:	normal
Priority:	High
Version:	2006.1
Hardware:	x86
OS:	Linux
Whiteboard:
Package list:		Runtime testing required:	---
Attachments:	smpeg-0.4.4-missing-init.patch

Description Vincent Le Ligeour 2007-01-07 22:46:09 UTC

When an non-openable file is given to SMPEG_new, it doesn't return a NULL pointer (this is normal behavior) but the status MPEG class member is not properly initialized. The SMPEG_delete on the object created will then segfault because of a NULL pointer test not initialized.
(can be test with the current ultrastar-ng cvs version)

Reproducible: Always

Steps to Reproduce:
1.Create an SMPEG object with a non-existant file with SMPEG_new
2.Try to delete it with SMPEG_delete

In portage.  Thanks for the bug report and patch.

It seems like a pretty obscure corner case so I didn't rev bump it.  Remerge for the patch.
