-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA512 - ------------------------------------------------------------------------- Debian Security Advisory DSA-4104-1 security@xxxxxxxxxx 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 Further information about Debian Security Advisories, how to apply these updates to your system and frequently asked questions can be found at: https://www.debian.org/security/ Mailing list: debian-security-announce@xxxxxxxxxxxxxxxx -----BEGIN PGP SIGNATURE----- iQKTBAEBCgB9FiEERkRAmAjBceBVMd3uBUy48xNDz0QFAlp3b2tfFIAAAAAALgAo aXNzdWVyLWZwckBub3RhdGlvbnMub3BlbnBncC5maWZ0aGhvcnNlbWFuLm5ldDQ2 NDQ0MDk4MDhDMTcxRTA1NTMxRERFRTA1NENCOEYzMTM0M0NGNDQACgkQBUy48xND z0TrkA//VNLdog0TJNf4fHBagj2qd9UFUInov6I6r4Bc0nfuyL66LY57riC8yLnF jiqq3+q86aXqokRO6/enP2v8d4OCS/jcZhMFmg86CE+1em+jBFdUcNijZUzIZjpA pEEbfNCYZ+aOrhDHAZn4HvjCnxRk5zseGmvfCNPtbJOxbeUh5tVcbXy/2768t/v0 s9n9cAI1BsvE/4M6/6PH/HEemJbHQpYUi+cE2WR0GEAszQd4U988Vf4LG/1ZhuN9 /rpfbvDw/OwTYlWFQyvzPl+lnyWrUXgY5EYrhllNXBUFfIzQg+NqlapWj37AR54+ 1UI4FVTjmcio6DYvtCfG704oL2yviKjxPddOSg+nJBuQTOcpskJtQPXHq3k0ELRE vWRehSemSj+XhZI9NV7TQ0n2UQfUQTIK04l2LOxN7Uozf7S6rRe653TFnk4VGsLi 1CQr1ek7YwepfSuaLl2eyUZl6xe3tFIeDtDbTLU9g1Cv8RIlMOU1KiVaSPhfjO/3 Gnx29JzqwM216gQl/8N9SUA7vtZJDbwAwzo/bMDHEpvvoqR4jVEKK4pLRm9UsQyX EKT26ZJqEuegV792xcowNpvn3s2H0TM+3u6DLGHUq2xC2TgsgHYy5zWeDnnx/5R2 yr0F9qPl9kefqabDCM4Tqvu32YYym5UUIqiq+iYQaDwDorDx7Bo= =T7ze -----END PGP SIGNATURE-----
