An issue has been found in slirp, a SLIP/PPP emulator using a dial up shell account. Due to bad memory handling in slirp a heap-based buffer overflow or other out-of-bounds access could happen, which can lead to a DoS or potential execute arbitrary code.
For Debian 8 ‘Jessie’, this problem has been fixed in version 1:1.0.17-7+deb8u1.
We recommend that you upgrade your slirp packages.
NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
