Beschreibung:	Summary: The remote host is missing an update for the 'gpac' package(s) announced via the MGASA-2021-0431 advisory. Vulnerability Insight: A specially crafted MPEG-4 input when decoding the atom for the 'co64' FOURCC can cause an integer overflow due to unchecked arithmetic resulting in a heap-based buffer overflow that causes memory corruption. (CVE-2021-21834) A specially crafted MPEG-4 input using the 'ctts' FOURCC code can cause an integer overflow due to unchecked arithmetic resulting in a heap-based buffer overflow that causes memory corruption. (CVE-2021-21836) A specially crafted MPEG-4 input can cause an integer overflow due to unchecked arithmetic resulting in a heap-based buffer overflow that causes memory corruption. (CVE-2021-21837, CVE-2021-21838, CVE-2021-21839) A specially crafted MPEG-4 input used to process an atom using the 'saio' FOURCC code cause an integer overflow due to unchecked arithmetic resulting in a heap-based buffer overflow that causes memory corruption. (CVE-2021-21840) A specially crafted MPEG-4 input when reading an atom using the 'sbgp' FOURCC code can cause an integer overflow due to unchecked arithmetic resulting in a heap-based buffer overflow that causes memory corruption. (CVE-2021-21841) A specially crafted MPEG-4 input can cause an integer overflow when processing an atom using the 'ssix' FOURCC code, due to unchecked arithmetic resulting in a heap-based buffer overflow that causes memory corruption. (CVE-2021-21842) A specially crafted MPEG-4 input can cause an integer overflow due to unchecked arithmetic resulting in a heap-based buffer overflow that causes memory corruption. After validating the number of ranges, at [41] the library will multiply the count by the size of the GF_SubsegmentRangeInfo structure. On a 32-bit platform, this multiplication can result in an integer overflow causing the space of the array being allocated to be less than expected. (CVE-2021-21843) A specially crafted MPEG-4 input when encountering an atom using the 'stco' FOURCC code, can cause an integer overflow due to unchecked arithmetic resulting in a heap-based buffer overflow that causes memory corruption. (CVE-2021-21844) A specially crafted MPEG-4 input in 'stsc' decoder can cause an integer overflow due to unchecked arithmetic resulting in a heap-based buffer overflow that causes memory corruption. (CVE-2021-21845) A specially crafted MPEG-4 input in 'stsz&' decoder can cause an integer overflow due to unchecked arithmetic resulting in a heap-based buffer overflow that causes memory corruption. (CVE-2021-21846) A specially crafted MPEG-4 input in 'stts' decoder can cause an integer overflow due to unchecked arithmetic resulting in a heap-based buffer overflow that causes memory corruption. (CVE-2021-21847) The library will actually reuse the parser for atoms with the 'stsz' FOURCC code when parsing atoms that use the 'stz2' FOURCC code and can cause an integer overflow due to unchecked arithmetic resulting in a heap-based buffer overflow that causes memory ... [Please see the references for more information on the vulnerabilities] Affected Software/OS: 'gpac' package(s) on Mageia 8. Solution: Please install the updated package(s).
