EUVDB-ID: #VU25458
Risk: Low
CVSSv3.1: 6.8 [CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H/E:U/RL:O/RC:C]
CVE-ID: CVE-2020-7039
CWE-ID:
CWE-122 - Heap-based Buffer Overflow
Exploit availability: No
DescriptionThe vulnerability allows an attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error within the tcp_emu() function in tcp_subr.c in libslirp. An attacker can issue specially crafted IRC DCC commands in EMU_IRC, trigger heap-based buffer overflow and execute arbitrary code on the target system.

CVE-ID: CVE-2020-8608
CWE-ID:
CWE-119 - Memory corruption
Exploit availability: No
DescriptionThe vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to a boundary error within tcp_subr.c file in libslirp. A local user can pass specially crafted data to the application that is using the affected version of library, trigger memory corruption and execute arbitrary code on the system.
