CVE ID : CVE-2017-9462 CVE-2017-1000115 CVE-2017-1000116
Debian Bug : 861243 871709 871710
Several issues were discovered in Mercurial, a distributed revision
control system.
CVE-2017-9462 (fixed in stretch only)
Jonathan Claudius of Mozilla discovered that repositories served
over stdio could be tricked into granting authorized users access to
the Python debugger.
CVE-2017-1000115
Mercurial's symlink auditing was incomplete, and could be abused to
write files outside the repository.
CVE-2017-1000116
Joern Schneeweisz discovered that Mercurial did not correctly handle
maliciously constructed ssh:// URLs. This allowed an attacker to run
an arbitrary shell command.
For the oldstable distribution (jessie), these problems have been fixed
in version 3.1.2-2+deb8u4.
For the stable distribution (stretch), these problems have been fixed in
version 4.0-1+deb9u1.
We recommend that you upgrade your mercurial packages.
