Immunix OS Security Advisory
Packages updated: slrn
Affected products: Immunix OS 6.2, 7.0-beta, and 7.0
Bugs Fixed: immunix/1507
Date: March 15, 2001
Advisory ID: IMNX-2001-70-007-01
Author: Greg Kroah-Hartman <[email protected]>
-----------------------------------------------------------------------
Description:
A buffer overflow in the slrn news reader has been reported by Bill
Nottingham. This buffer is created on the heap, so it is not
protected from overflows by the StackGuard compiler (more information
detailing the overflows that StackGuard does protect against can be
found at http://immunix.org/stackguard.html )
This overflow can occur by creating a very long header in a news
message. Some messages that can cause the slrn news reader to crash
have been detected in the wild, but no exploits are currently known at
this time.
Immunix 7.0 does not install the slrn packages by default but provides
them in the extras/unsupported directory so they do not need to be
upgraded unless they have been installed manually by the system
administrator.
Packages have been created and released that fix these problems.
