Overview

Apache Portable Runtime Utility (APR-util) 1.6.0 and prior fail to validate the integrity of SDBM database files used by apr_sdbm*() functions, resulting in a possible out of bound read access. A local user with write access to the database can make a program or process using these functions crash, and cause a denial of service.

Overview

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.

Overview

Affected versions of this package are vulnerable to Link Following avahi-daemon-check-dns.sh in the Debian avahi package through 0.8-4 is executed as root via /etc/network/if-up.d/avahi-daemon, and allows a local attacker to cause a denial of service or create arbitrary empty files via a symlink attack on files under /run/avahi-daemon. NOTE: this only affects the packaging for Debian GNU/Linux (used indirectly by SUSE), not the upstream Avahi product.

Remediation

There is no fixed version for avahi.

Overview

An issue was discovered in disable_priv_mode in shell.c in GNU Bash through 5.0 patch 11. By default, if Bash is run with its effective UID not equal to its real UID, it will drop privileges by setting its effective UID to its real UID. However, it does so incorrectly. On Linux and other systems that support "saved UID" functionality, the saved UID is not dropped. An attacker with command execution in the shell can use "enable -f" for runtime loading of a new builtin, which can be a shared object that calls setuid() and therefore regains privileges. However, binaries running with an effective UID of 0 are unaffected.

Overview

Affected versions of this package are vulnerable to Improper Input Validation. A flaw exists in binutils in bfd/pef.c. An attacker who is able to submit a crafted PEF file to be parsed by objdump could cause a heap buffer overflow -> out-of-bounds read that could lead to an impact to application availability. This flaw affects binutils versions prior to 2.34.

Overview

The _bfd_XX_bfd_copy_private_bfd_data_common function in peXXigen.c in the Binary File Descriptor (BFD) library (aka libbfd), as distributed in GNU Binutils 2.30, processes a negative Data Directory size with an unbounded loop that increases the value of (external_IMAGE_DEBUG_DIRECTORY) *edd so that the address exceeds its own memory region, resulting in an out-of-bounds memory write, as demonstrated by objcopy copying private info with _bfd_pex64_bfd_copy_private_bfd_data_common in pex64igen.c.

Overview

The demangle_template function in cplus-dem.c in GNU libiberty, as distributed in GNU Binutils 2.31.1, contains an integer overflow vulnerability (for "Create an array for saving the template argument values") that can trigger a heap-based buffer overflow, as demonstrated by nm.

Overview

An issue was discovered in cp-demangle.c in GNU libiberty, as distributed in GNU Binutils 2.31. There is a stack consumption problem caused by the cplus_demangle_type function making recursive calls to itself in certain scenarios involving many 'P' characters.

Overview

An issue was discovered in arm_pt in cplus-dem.c in GNU libiberty, as distributed in GNU Binutils 2.30. Stack Exhaustion occurs in the C++ demangling functions provided by libiberty, and there are recursive stack frames: demangle_arm_hp_template, demangle_class_name, demangle_fund_type, do_type, do_arg, demangle_args, and demangle_nested_args. This can occur during execution of nm-new.
