ID CVE-2015-5259
Summary Integer overflow in the read_string function in libsvn_ra_svn/marshal.c in Apache Subversion 1.9.x before 1.9.3 allows remote attackers to execute arbitrary code via an svn:// protocol string, which triggers a heap-based buffer overflow and an out-of-bounds read.

    description It was found that when an SVN server (both svnserve and httpd with the mod_dav_svn module) searched the history of a file or a directory, it would disclose its location in the repository if that file or directory was not readable (for example, if it had been moved). (CVE-2015-3187) An integer overflow was discovered allowing remote attackers to execute arbitrary code via an svn:// protocol string, which triggers a heap-based buffer overflow and an out-of-bounds read. (CVE-2015-5259) It was found that the mod_authz_svn module did not properly restrict anonymous access to Subversion repositories under certain configurations when used with Apache httpd 2.4.x. This could allow a user to anonymously access files in a Subversion repository, which should only be accessible to authenticated users. (CVE-2015-3184) It was found that the mod_dav_svn module was vulnerable to a remotely triggerable heap-based buffer overflow and out-of-bounds read caused by an integer overflow when parsing skel-encoded request bodies, allowing an attacker with write access to a repository to cause a denial of service attack (on 32-bit or 64-bit servers) or possibly execute arbitrary code (on 32-bit servers only) under the context of the httpd process.

    description This update includes the latest stable release of _Apache Subversion 1.8_, version **1.8.15**. This update fixes two security issues: * **CVE-2015-3184**: Subversion's mod_authz_svn does not properly restrict anonymous access in some mixed anonymous/authenticated environments when using Apache httpd 2.4. http://subversion.apache.org/security/CVE-2015-3184-advisory.txt * **CVE-2015-3187**: Subversion servers, both httpd and svnserve, will reveal some paths that should be hidden by path-based authz. http://subversion.apache.org/security/CVE-2015-3187-advisory.txt ### User- visible changes: #### Client-side bugfixes: * gpg-agent: fix crash with non- canonical $HOME * document svn:autoprops * cp: fix 'svn cp ^/A/D/H at 1 ^/A' to properly create A * resolve: improve conflict prompts for binary files * ls: improve performance of '-v' on tag directories * improved Sqlite 3.8.9 query performance regression on externals * fixed [issue 4580](http://subversion.tigris.org/issues/show_bug.cgi?id=4580): 'svn -v st' on file externals reports '?' instead of user and revision after 'svn up' #### Client-side and server-side bugfixes: * fix a segfault with old style text delta #### Server-side bugfixes: * fsfs: reduce memory allocation with Apache * mod_dav_svn: emit first log items as soon as possible * mod_dav_svn: use LimitXMLRequestBody for skel-encoded requests * mod_dav_svn: do not ignore skel parsing errors * detect invalid svndiff data earlier * prevent possible repository corruption on power/disk failures * fixed [issue 4577](http://subversion.tigris.org/issues/show_bug.cgi?id=4577): Read error with nodes whose DELTA chain starts with a PLAIN rep * fixed [issue 4531](http://subversion.tigris.org/issues/show_bug.cgi?id=4531): server-side copy (over dav) is slow and uses too much memory #### Bindings bugfixes: * swig: fix memory corruption in svn_client_copy_source_t ### Developer-visible changes: #### General: * avoid failing some tests on versions of Python with a very old sqlite * fix Ruby tests so they don't use the users real configuration #### Bindings: * swig-pl: fix some stack memory problems Note that Tenable Network Security has extracted the preceding description block directly from the Fedora security advisory.
