Advancecomp v2.3 was discovered to contain a heap buffer overflow via the component __interceptor_memcpy at /sanitizer_common/sanitizer_common_interceptors.inc.
In AdvanceCOMP 2.1, png_compress in pngex.cc in advpng has an integer overflow upon encountering an invalid PNG size, which results in an attempted memcpy to write into a buffer that is too small. (There is also a heap-based buffer over-read.)
An issue was discovered in AdvanceCOMP through 2.1. A NULL pointer dereference exists in the function be_uint32_read() located in endianrw.h. It can be triggered by sending a crafted file to a binary. It allows an attacker to cause a Denial of Service (Segmentation fault) or possibly have unspecified other impact when a victim opens a specially crafted file.
