CVE-2021-3595 |
An invalid pointer initialization issue was found in the SLiRP networking implementation of QEMU. The flaw exists in the tftp_input() function and could occur while processing a udp packet that is smaller than the size of the 'tftp_t' structure. This issue may lead to out-of-bounds read access or indirect host memory disclosure to the guest. The highest threat from this vulnerability is to data confidentiality. This flaw affects libslirp versions prior to 4.6.0. Published: June 15, 2021; 5:15:10 PM -0400 |
V4.0:(not available) V3.1: 3.8 LOW V2.0: 2.1 LOW |
CVE-2021-3594 |
An invalid pointer initialization issue was found in the SLiRP networking implementation of QEMU. The flaw exists in the udp_input() function and could occur while processing a udp packet that is smaller than the size of the 'udphdr' structure. This issue may lead to out-of-bounds read access or indirect host memory disclosure to the guest. The highest threat from this vulnerability is to data confidentiality. This flaw affects libslirp versions prior to 4.6.0. Published: June 15, 2021; 5:15:09 PM -0400 |
V4.0:(not available) V3.1: 3.8 LOW V2.0: 2.1 LOW |
CVE-2021-3593 |
An invalid pointer initialization issue was found in the SLiRP networking implementation of QEMU. The flaw exists in the udp6_input() function and could occur while processing a udp packet that is smaller than the size of the 'udphdr' structure. This issue may lead to out-of-bounds read access or indirect host memory disclosure to the guest. The highest threat from this vulnerability is to data confidentiality. This flaw affects libslirp versions prior to 4.6.0. Published: June 15, 2021; 5:15:09 PM -0400 |
V4.0:(not available) V3.1: 3.8 LOW V2.0: 2.1 LOW |
CVE-2021-3592 |
An invalid pointer initialization issue was found in the SLiRP networking implementation of QEMU. The flaw exists in the bootp_input() function and could occur while processing a udp packet that is smaller than the size of the 'bootp_t' structure. A malicious guest could use this flaw to leak 10 bytes of uninitialized heap memory from the host. The highest threat from this vulnerability is to data confidentiality. This flaw affects libslirp versions prior to 4.6.0. Published: June 15, 2021; 5:15:09 PM -0400 |
V4.0:(not available) V3.1: 3.8 LOW V2.0: 2.1 LOW |
CVE-2020-29130 |
slirp.c in libslirp through 4.3.1 has a buffer over-read because it tries to read a certain amount of header data even if that exceeds the total packet length. Published: November 26, 2020; 3:15:10 PM -0500 |
V4.0:(not available) V3.1: 4.3 MEDIUM V2.0: 4.0 MEDIUM |
CVE-2020-29129 |
ncsi.c in libslirp through 4.3.1 has a buffer over-read because it tries to read a certain amount of header data even if that exceeds the total packet length. Published: November 26, 2020; 3:15:10 PM -0500 |
V4.0:(not available) V3.1: 4.3 MEDIUM V2.0: 4.0 MEDIUM |
CVE-2020-10756 |
An out-of-bounds read vulnerability was found in the SLiRP networking implementation of the QEMU emulator. This flaw occurs in the icmp6_send_echoreply() routine while replying to an ICMP echo request, also known as ping. This flaw allows a malicious guest to leak the contents of the host memory, resulting in possible information disclosure. This flaw affects versions of libslirp before 4.3.1. Published: July 09, 2020; 12:15:13 PM -0400 |
V4.0:(not available) V3.1: 6.5 MEDIUM V2.0: 2.1 LOW |
CVE-2020-1983 |
A use after free vulnerability in ip_reass() in ip_input.c of libslirp 4.2.0 and prior releases allows crafted packets to cause a denial of service. Published: April 22, 2020; 4:15:11 PM -0400 |
V4.0:(not available) V3.1: 6.5 MEDIUM V2.0: 2.1 LOW |
