Vulnerability Description

Multiple integer overflows in the Apache Portable runtime (APR)  library or the Apache Portable Utility library (APR-util) are possible. 

This is due to an invalid pointer being returned on large memory allocations rather than a NULL pointer.

If an application using APR processed crafted input, a remote attacker could cause a denial of service or potentially execute arbitrary code as the user invoking the application.



Update the affected packages as show per version below:

  • Ubuntu 9.04 - libapr1 - 1.2.12-5ubuntu0.1
  • Ubuntu 8.10 - libapr1 - 1.2.12-4ubuntu0.1
  • Ubuntu 8.04 LTS - libapr1 - 1.2.11-1ubuntu0.1
