Description Dhananjay Arunesh 2019-05-10 08:42:32 UTC
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.

Comment 8 Marco Benatto 2019-05-16 21:42:18 UTC
There's a vulnerability on png library from advancecomp package where an attacker can cause improper heap data read or DoS by a crafted PNG
file. The advancecomp PNG library doesn't validate the image size, the lack of validation leads to a integer overflow when decoding PNG header
data. The overflown value is further used to perform memory allocation and access, this action causes heap-based overflow leading to improper
data reading from heap or causing DoS due to invalid memory access.

Comment 9 Marco Benatto 2019-05-16 21:47:45 UTC
