Detail
| 'landave' discovered a heap-based buffer overflow vulnerability in the NCompress::NShrink::CDecoder::CodeReal method in p7zip, a 7zr file archiver with high compression ratio. A remote attacker can take advantage of this flaw to cause a denial-of-service or, potentially the execution of arbitrary code with the privileges of the user running p7zip, if a specially crafted shrinked ZIP archive is processed. For the oldstable distribution (jessie), this problem has been fixed in version 9.20.1~dfsg.1-4.1+deb8u3. For the stable distribution (stretch), this problem has been fixed in version 16.02+dfsg-3+deb9u1. We recommend that you upgrade your p7zip packages. For the detailed security status of p7zip please refer to its security tracker page at: https://security-tracker.debian.org/tracker/p7zip |
