Debian Security Advisory DSA-4104-1 [email protected]
https://www.debian.org/security/ Salvatore Bonaccorso
February 04, 2018 https://www.debian.org/security/faq
Package : p7zip
CVE ID : CVE-2017-17969
Debian Bug : 888297
'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
