Heap-based buffer over-read in function png_convert_4 in file pngex.cc in AdvanceMAME through 2.1.

A segmentation fault flaw was found in the Advancecomp package. This may lead to decreased availability.

Advancecomp v2.3 was discovered to contain a heap buffer overflow via the component __interceptor_memcpy at /sanitizer_common/sanitizer_common_interceptors.inc.

Advancecomp v2.3 was discovered to contain a segmentation fault.

Advancecomp v2.3 was discovered to contain a segmentation fault.

Advancecomp v2.3 was discovered to contain a heap buffer overflow.

Advancecomp v2.3 was discovered to contain a heap buffer overflow.

Advancecomp v2.3 was discovered to contain a heap buffer overflow via le_uint32_read at /lib/endianrw.h.

Advancecomp v2.3 contains a segmentation fault.

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. An invalid memory address occurs in the function adv_png_unfilter_8 in lib/png.c. 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.

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.

An out-of-bounds heap buffer read flaw was found in the way advancecomp before 2.1-2018/02 handled processing of ZIP files. An attacker could potentially use this flaw to crash the advzip utility by tricking it into processing crafted ZIP files.
