Package: advancecomp Version: 2.0-1 Severity: normal Dear Maintainer,
Running 'advmng -l' with the attached file raises a NULL pointer dereference, which may allow a denial-of-service attack of a malicious attacker. I expected the program to terminate without segfault, but the program crashes as follow. ---------------------------- (gdb) r -l poc Starting program: /usr/bin/advmng -l poc Program received signal SIGSEGV, Segmentation fault. 0x000055555556037f in ?? () (gdb) x/i $rip => 0x55555556037f: movzwl 0x0(%rbp),%r13d (gdb) i r rbp rbp 0x0 0x0 ----------------------------- The bug was found with a fuzzer developed by 'SoftSec' group at KAIST. -- System Information: Debian Release: 9.2 APT prefers stable-updates APT policy: (500, 'stable-updates'), (500, 'testing'), (500, 'stable') Architecture: amd64 (x86_64) Kernel: Linux 4.9.0-3-amd64 (SMP w/1 CPU core) Locale: LANG=en_US.UTF-8, LC_CTYPE=en_US.UTF-8 (charmap=UTF-8), LANGUAGE=en_US.UTF-8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Init: systemd (via /run/systemd/system) Versions of packages advancecomp depends on: ii libc6 2.24-11+deb9u1 ii libgcc1 1:6.3.0-18 ii libstdc++6 6.3.0-18 ii zlib1g 1:1.2.8.dfsg-5 advancecomp recommends no packages. advancecomp suggests no packages. -- no debconf information
