Portable Runtime

Lax permissions set by the Apache Portable Runtime library on Unix platforms would allow local users read access to named shared memory segments, potentially revealing sensitive application data. This issue does not affect non-Unix platforms, or builds with APR_USE_SHMEM_SHMGET=1 (apr.h) Users are recommended to upgrade to APR version 1.7.5, which fixes this issue.

On Windows, Apache Portable Runtime 1.7.0 and earlier may write beyond the end of a stack based buffer in apr_socket_sendv(). This is a result of integer overflow.

When apr_time_exp*() or apr_os_exp_time*() functions are invoked with an invalid month field value in Apache Portable Runtime APR 1.6.2 and prior, out of bounds memory may be accessed in converting this value to an apr_time_exp_t value, potentially revealing the contents of a different static heap value or resulting in program termination, and may represent an information disclosure or denial of service vulnerability to applications which call these APR functions with unvalidated external input.

tables/apr_hash.c in the Apache Portable Runtime (APR) library through 1.4.5 computes hash values without restricting the ability to trigger hash collisions predictably, which allows context-dependent attackers to cause a denial of service (CPU consumption) via crafted input to an application that maintains a hash table.

Stack consumption vulnerability in the fnmatch implementation in apr_fnmatch.c in the Apache Portable Runtime (APR) library before 1.4.3 and the Apache HTTP Server before 2.2.18, and in fnmatch.c in libc in NetBSD 5.1, OpenBSD 4.8, FreeBSD, Apple Mac OS X 10.6, Oracle Solaris 10, and Android, allows context-dependent attackers to cause a denial of service (CPU and memory consumption) via *? sequences in the first argument, as demonstrated by attacks against mod_autoindex in httpd.
