Package name ncompress
Date August 9th, 2006
Advisory ID MDKSA-2006:140
Affected versions CS3.0, 2006.0
Synopsis Updated ncompress packages fix vulnerability

Problem Description

Tavis Ormandy, of the Google Security Team, discovered that ncompress,
when uncompressing data, performed no bounds checking, which could
allow a specially crafted datastream to underflow a .bss buffer with
attacker controlled data.

Updated packages have been patched to correct this issue.
