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

In AdvanceCOMP 2.1, pngcompress 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 advpngunfilter8 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 beuint32read() 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.

Heap-based buffer over-read in function pngconvert4 in file pngex.cc in AdvanceMAME through 2.1.
