Description
This security bulletin contains information about 10 secuirty vulnerabilities.
1) Buffer overflow (CVE-ID: CVE-2019-9770)
The vulnerability allows a remote non-authenticated attacker to perform a denial of service (DoS) attack.
An issue was discovered in GNU LibreDWG 0.7 and 0.7.1645. There is a heap-based buffer overflow in the function dwg_decode_eed_data at decode.c for the y dimension.
2) NULL pointer dereference (CVE-ID: CVE-2019-9771)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a NULL pointer dreference error in function bit_convert_TU at bits.c. A remote attacker can perform a denial of service (DoS) attack.
3) NULL pointer dereference (CVE-ID: CVE-2019-9772)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a NULL pointer dreference error in function dwg_dxf_LEADER at dwg.spec. A remote attacker can perform a denial of service (DoS) attack.
4) Buffer overflow (CVE-ID: CVE-2019-9773)
The vulnerability allows a remote non-authenticated attacker to perform a denial of service (DoS) attack.
An issue was discovered in GNU LibreDWG 0.7 and 0.7.1645. There is a heap-based buffer overflow in the function dwg_decode_eed_data at decode.c for the z dimension.
5) Out-of-bounds read (CVE-ID: CVE-2019-9774)
The vulnerability allows a remote non-authenticated attacker to #BASIC_IMPACT#.
An issue was discovered in GNU LibreDWG 0.7 and 0.7.1645. There is an out-of-bounds read in the function bit_read_B at bits.c.
6) Out-of-bounds read (CVE-ID: CVE-2019-9775)
The vulnerability allows a remote non-authenticated attacker to #BASIC_IMPACT#.
An issue was discovered in GNU LibreDWG 0.7 and 0.7.1645. There is an out-of-bounds read in the function dwg_dxf_BLOCK_CONTROL at dwg.spec.
7) NULL pointer dereference (CVE-ID: CVE-2019-9776)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a NULL pointer dreference error in function dwg_dxf_LTYPE at dwg.spec (later than CVE-2019-9779). A remote attacker can perform a denial of service (DoS) attack.
8) Out-of-bounds read (CVE-ID: CVE-2019-9777)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to heap-based buffer over-read in the function dxf_header_write at header_variables_dxf.spec. A remote attacker can perform a denial of service attack.
9) Out-of-bounds read (CVE-ID: CVE-2019-9778)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to heap-based buffer over-read in the function dwg_dxf_LTYPE at dwg.spec. A remote attacker can perform a denial of service attack.
10) NULL pointer dereference (CVE-ID: CVE-2019-9779)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a NULL pointer dreference error in function dwg_dxf_LTYPE at dwg.spec (earlier than CVE-2019-9776). A remote attacker can perform a denial of service (DoS) attack.
