From 03af77d4ca60a21f3dca1ab10ef2ba17ec2f96c9 Mon Sep 17 00:00:00 2001 From: Julian Andres Klode Date: Mon, 9 Apr 2018 15:32:09 +0200 Subject: Import Debian version 1.0.1ubuntu2.18 apt (1.0.1ubuntu2.18) trusty; urgency=medium * ExecFork: Use /proc/self/fd to determine which files to close (Closes: #764204) (LP: #1332440). apt (1.0.1ubuntu2.17) trusty-security; urgency=high * SECURITY UPDATE: gpgv: Check for errors when splitting files (CVE-2016-1252) Thanks to Jann Horn, Google Project Zero for reporting the issue (LP: #1647467) apt (1.0.1ubuntu2.15) trusty; urgency=medium * Fixes failure to download the Package index file when using mirror:// URL in sources.list and the archive fails to profile a file. APT would try the next archive in the list for .deb packages but did not retry when the index file failed to download. (LP: #1625667) apt (1.0.1ubuntu2.14) trusty; urgency=medium * When using the https transport mechanism, $no_proxy is ignored if apt is getting it's proxy information from $https_proxy (as opposed to Acquire::https::Proxy somewhere in apt config). If the source of proxy information is Acquire::https::Proxy set in apt.conf (or apt.conf.d), then $no_proxy is honored. This patch makes the behavior similar for both methods of setting the proxy. (LP: #1575877) apt (1.0.1ubuntu2.13) trusty; urgency=medium * Recheck Pre-Depends satisfaction in SmartConfigure, to avoid unconfigured Pre-Depends (which dpkg later fails on). Fixes upgrade failures of systemd, util-linux, and other packages with Pre-Depends. Many thanks to David Kalnischkies for figuring out the patch and Winfried PLappert for testing! Patch taken from Debian git. (LP: #1560797) apt (1.0.1ubuntu2.12) trusty; urgency=medium [ Colin Watson ] * Fix lzma write support to handle "try again" case (closes: #751688, LP: #1553770). [ David Kalnischkies ] * Handle moved mmap after UniqFindTagWrite call (closes: #753941, LP: #1445436). apt (1.0.1ubuntu2.11) trusty; urgency=medium * apt-pkg/packagemanager.cc: - fix incorrect configure ordering in the SmartConfigure step by skipping packages that do not need immediate action. (LP: #1347721, #1497688) apt (1.0.1ubuntu2.10) trusty; urgency=medium * Fix regression from the previous upload by ensuring we're actually testing for the right member before iterating on it (LP: #1480592) apt (1.0.1ubuntu2.9) trusty; urgency=medium * Fix regression in the Never-MarkAuto-Sections feature caused by the previous auto-removal fix, with inspiration drawn from the patches and conversation from http://bugs.debian.org/793360 (LP: #1479207) apt (1.0.1ubuntu2.8) trusty-proposed; urgency=low * fix crash for packages that have no section in their instVersion (LP: #1449394) apt (1.0.1ubuntu2.7) trusty-proposed; urgency=low * fix auto-removal behavior (thanks to Adam Conrad) LP: #1429041 apt (1.0.1ubuntu2.6) trusty-proposed; urgency=medium * apt-pkg/deb/dpkgpm.cc: - update string matching for dpkg I/O errors. (LP: #1363257) - properly parse the dpkg status line so that package name is properly set and an apport report is created. Thanks to Anders Kaseorg for the patch. (LP: #1353171) apt (1.0.1ubuntu2.5) trusty-security; urgency=low * SECURITY UPDATE: - cmdline/apt-get.cc: fix insecure tempfile handling in apt-get changelog (CVE-2014-7206). Thanks to Guillem Jover apt (1.0.1ubuntu2.4.1) trusty-security; urgency=low * SECURITY UPDATE: - fix potential buffer overflow, thanks to the Google Security Team (CVE-2014-6273) * Fix regression from the previous upload when file:/// sources are used and those are on a different partition than the apt state directory * Fix regression when Dir::state::lists is set to a relative path * Fix regression when cdrom: sources got rewriten by apt-cdrom add apt (1.0.1ubuntu2.3) trusty-security; urgency=low * SECURITY UPDATE: - incorrect invalidating of unauthenticated data (CVE-2014-0488) - incorect verification of 304 reply (CVE-2014-0487) - incorrect verification of Acquire::Gzip indexes (CVE-2014-0489) --- methods/copy.cc | 38 ++++++++++++++++++++++++++++++-------- methods/http.cc | 24 +++++++++++------------- methods/https.cc | 12 ++++++------ 3 files changed, 47 insertions(+), 27 deletions(-) (limited to 'methods') diff --git a/methods/copy.cc b/methods/copy.cc index d59f032ff..cc0ee6554 100644 --- a/methods/copy.cc +++ b/methods/copy.cc @@ -16,6 +16,7 @@ #include #include #include +#include #include #include @@ -27,19 +28,35 @@ class CopyMethod : public pkgAcqMethod { virtual bool Fetch(FetchItem *Itm); - + void CalculateHashes(FetchResult &Res); + public: - CopyMethod() : pkgAcqMethod("1.0",SingleInstance) {}; + CopyMethod() : pkgAcqMethod("1.0",SingleInstance|SendConfig) {}; }; +void CopyMethod::CalculateHashes(FetchResult &Res) +{ + // For gzip indexes we need to look inside the gzip for the hash + // We can not use the extension here as its not used in partial + // on a IMS hit + FileFd::OpenMode OpenMode = FileFd::ReadOnly; + if (_config->FindB("Acquire::GzipIndexes", false) == true) + OpenMode = FileFd::ReadOnlyGzip; + + Hashes Hash; + FileFd Fd(Res.Filename, OpenMode); + Hash.AddFD(Fd); + Res.TakeHashes(Hash); +} + // CopyMethod::Fetch - Fetch a file /*{{{*/ // --------------------------------------------------------------------- /* */ bool CopyMethod::Fetch(FetchItem *Itm) { URI Get = Itm->Uri; - std::string File = Get.Path; + std::string File = Get.Host + Get.Path; // To account for relative paths // Stat the file and send a start message struct stat Buf; @@ -53,7 +70,15 @@ bool CopyMethod::Fetch(FetchItem *Itm) Res.LastModified = Buf.st_mtime; Res.IMSHit = false; URIStart(Res); - + + // when the files are identical, just compute the hashes + if(File == Itm->DestFile) + { + CalculateHashes(Res); + URIDone(Res); + return true; + } + // See if the file exists FileFd From(File,FileFd::ReadOnly); FileFd To(Itm->DestFile,FileFd::WriteAtomic); @@ -82,10 +107,7 @@ bool CopyMethod::Fetch(FetchItem *Itm) if (utimes(Res.Filename.c_str(), times) != 0) return _error->Errno("utimes",_("Failed to set modification time")); - Hashes Hash; - FileFd Fd(Res.Filename, FileFd::ReadOnly); - Hash.AddFD(Fd); - Res.TakeHashes(Hash); + CalculateHashes(Res); URIDone(Res); return true; diff --git a/methods/http.cc b/methods/http.cc index ed6e3517d..d3a5d718f 100644 --- a/methods/http.cc +++ b/methods/http.cc @@ -667,7 +667,7 @@ void HttpMethod::SendReq(FetchItem *Itm) URI Uri = Itm->Uri; // The HTTP server expects a hostname with a trailing :port - char Buf[1000]; + string Buf; string ProperHost; if (Uri.Host.find(':') != string::npos) @@ -676,14 +676,10 @@ void HttpMethod::SendReq(FetchItem *Itm) ProperHost = Uri.Host; if (Uri.Port != 0) { - sprintf(Buf,":%u",Uri.Port); + strprintf(Buf,":%u",Uri.Port); ProperHost += Buf; } - // Just in case. - if (Itm->Uri.length() >= sizeof(Buf)) - abort(); - /* RFC 2616 ยง5.1.2 requires absolute URIs for requests to proxies, but while its a must for all servers to accept absolute URIs, it is assumed clients will sent an absolute path for non-proxies */ @@ -701,25 +697,27 @@ void HttpMethod::SendReq(FetchItem *Itm) in 1.1, can cause problems with proxies, and we are an HTTP/1.1 client anyway.
