The remote Debian host is missing a security update.


It was discovered that there was an out-of-bounds memory vulnerability in apr, a support/portability library for various applications.

When the apr_exp_time*() or apr_os_exp_time*() functions were invoked with an invalid month field value, out of bounds memory may have been be accessed when converting this value to an apr_time_exp_t value.
This could have potentially revealed the contents of a different static heap value or resulted in program termination.

For Debian 7 'Wheezy', this issue has been fixed in apr version 1.4.6-3+deb7u2.

We recommend that you upgrade your apr packages.

NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.


Upgrade the affected libapr1, libapr1-dbg, and libapr1-dev packages.
