Heap-based Buffer Overflow

A heap overflow condition is a buffer overflow, where the buffer that can be overwritten is allocated in the heap portion of memory, generally meaning that the buffer was allocated using a routine such as malloc().

A heap buffer overflow vulnerability in the UPF component of free5GC v4.0.1 allows remote attackers to cause a denial of service via a crafted PFCP Session Modification Request. The issue occurs in the SDFFilterFields.UnmarshalBinary function (sdf-filter.go) when processing a declared length that exceeds the actual buffer capacity, leading to a runtime panic and UPF crash.Show less

navigation2 is a ROS 2 Navigation Framework and System. In 1.3.11 and earlier, a critical heap out-of-bounds write vulnerability exists in Nav2 AMCL's particle filter clustering logic. By publishing a single crafted geometry_msgs/PoseWithCovarianceStamped message with extreme covariance values to the /initialpose topic, an unauthenticated attacker on the same ROS 2 DDS domain can trigger a negative index write (set->clusters[-1]) into heap memory preceding the allocated buffer. In Release builds, the sole boundary check (assert) is compiled out, leaving zero runtime protection. This primitive allows controlled corruption of the heap chunk metadata(at least the size of the heap chunk where the set->clusters is in is controllable by the attacker), potentially leading to further exploitation. At minimum, it provides a reliable single-packet denial of service that kills localization and halts all navigation.Show less

LIBPNG is a reference library for use in applications that read, create, and manipulate PNG (Portable Network Graphics) raster image files. Prior to 1.6.55, an out-of-bounds read vulnerability exists in the png_set_quantize() API function. When the function is called with no histogram and the number of colors in the palette is more than twice the maximum supported by the user's display, certain palettes will cause the function to enter into an infinite loop that reads past the end of an internal heap-allocated buffer. The images that trigger this vulnerability are valid per the PNG specification. This vulnerability is fixed in 1.6.55.Show less
