- More information:
Multiple vulnerabilities have been discovered in Dulwich, a Python implementation of the file formats and protocols used by the Git version control system. The Common Vulnerabilities and Exposures project identifies the following problems:
It was discovered that Dulwich allows writing to files under .git/ when checking out working trees. This could lead to the execution of arbitrary code with the privileges of the user running an application based on Dulwich.
Ivan Fratric of the Google Security Team has found a buffer overflow in the C implementation of the apply_delta() function, used when accessing Git objects in pack files. An attacker could take advantage of this flaw to cause the execution of arbitrary code with the privileges of the user running a Git server or client based on Dulwich.
For the stable distribution (wheezy), these problems have been fixed in version 0.8.5-2+deb7u2.
For the upcoming stable distribution (jessie), these problems have been fixed in version 0.9.7-3.
For the unstable distribution (sid), these problems have been fixed in version 0.10.1-1.
We recommend that you upgrade your dulwich packages.
