Arch Linux Security Advisory ASA-201609-6 ========================================= Severity: Critical Date : 2016-09-09 CVE-ID : CVE-2016-2317 Package : graphicsmagick Type : multiple issues Remote : Yes Link : https://wiki.archlinux.org/index.php/CVE Summary ======= The package graphicsmagick before version 1.3.25-1 is vulnerable to multiple issues. Resolution ========== Upgrade to 1.3.25-1 # pacman -Syu "graphicsmagick>=1.3.25-1" The problem has been fixed upstream in version 1.3.25. Workaround ========== None. Description =========== 1. A last instance of CVE-2016-2317 (heap buffer overflow) in the MVG rendering code (also impacts SVG). This problem was originally reported by Gustavo Grieco. 2. A possible heap overflow of the EscapeParenthesis() function. While I was not able to reproduce it for myself, the implementation is replaced with a different algorithm. This problem was reported by Gustavo Grieco. 3. The Utah RLE reader did not validate that header information was reasonable given the file size and so it could cause huge memory allocations and/or consume huge amounts of CPU. This problem was reported by Agostino Sarubbo. 4. The TIFF reader had a bug pertaining to use of TIFFGetField() when a 'count' value is returned. The bug caused a heap read overflow (due to using strlcpy() to copy a possibly unterminated string) which could allow an untrusted file to crash the software. Impact ====== An remote attacker is able to create specially crafted files that, when opened or processed, may lead to denial of service or possibly arbitrary code execution.
