So only the last line or two get escaped. + +One way to fix this would be to read all lines into the pattern +space first. However, the included fix is even simpler: All lines +except the last line get a backslash appended at the end. To ensure +that shell command substitution doesn't eat a possible trailing +newline, a colon is appended to the filename before escaping. +The colon is later used to separate the filename from the grep +output so it is fine to add it here instead of a few lines later. + +The old code also wasn't POSIX compliant as it used \n in the +replacement section of the s-command. Using \<newline> is the +POSIX compatible method. + +LC_ALL=C was added to the two critical sed commands. POSIX sed +manual recommends it when using sed to manipulate pathnames +because in other locales invalid multibyte sequences might +cause issues with some sed implementations. In case of GNU sed, +these particular sed scripts wouldn't have such problems but some +other scripts could have, see: + + info '(sed)Locale Considerations' + +This vulnerability was discovered by: +cleemy desu wayo working with Trend Micro Zero Day Initiative + +Thanks to Jim Meyering and Paul Eggert discussing the different +ways to fix this and for coordinating the patch release schedule +with gzip. +--- + src/scripts/xzgrep.in | 20 ++++++++++++-------- + 1 file changed, 12 insertions(+), 8 deletions(-) + +diff --git a/src/scripts/xzgrep.in b/src/scripts/xzgrep.in +index b180936..e5186ba 100644 +--- a/src/scripts/xzgrep.in ++++ b/src/scripts/xzgrep.in +@@ -180,22 +180,26 @@ for i; do + { test $# -eq 1 || test $no_filename -eq 1; }; then + eval "$grep" + else ++ # Append a colon so that the last character will never be a newline ++ # which would otherwise get lost in shell command substitution. ++ i="$i:" ++ ++ # Escape & \ | and newlines only if such characters are present ++ # (speed optimization). + case $i in + (*' + '* | *'&'* | *'\'* | *'|'*) +- i=$(printf '%s\n' "$i" | +- sed ' +- $!N +- $s/[&\|]/\\&/g +- $s/\n/\\n/g +- ');; ++ i=$(printf '%s\n' "$i" | LC_ALL=C sed 's/[&\|]/\\&/g; $!s/$/\\/');; + esac +- sed_script="s|^|$i:|" ++ ++ # $i already ends with a colon so don't add it here. ++ sed_script="s|^|$i|" + + # Fail if grep or sed fails. + r=$( + exec 4>&1 +- (eval "$grep" 4>&-; echo $? >&4) 3>&- | sed "$sed_script" >&3 4>&- ++ (eval "$grep" 4>&-; echo $? >&4) 3>&- | ++ LC_ALL=C sed "$sed_script" >&3 4>&- + ) || r=2 + exit $r + fi >&3 5>&- +-- +2.35.1 + diff --git a/source/l/libaio/libaio.SlackBuild b/source/l/libaio/libaio.SlackBuild index a19f49c91..f61cc917b 100755 --- a/source/l/libaio/libaio.SlackBuild +++ b/source/l/libaio/libaio.SlackBuild @@ -24,7 +24,7 @@ cd $(dirname $0) ; CWD=$(pwd) PKGNAM=libaio VERSION=${VERSION:-$(echo $PKGNAM-*.tar.?z | rev | cut -f 3- -d . | cut -f 1 -d - | rev)} -BUILD=${BUILD:-3} +BUILD=${BUILD:-1} # Automatically determine the architecture we're building on: if [ -z "$ARCH" ]; then diff --git a/source/l/tevent/tevent.SlackBuild b/source/l/tevent/tevent.SlackBuild index d639c11c6..7bb29af57 100755 --- a/source/l/tevent/tevent.SlackBuild +++ b/source/l/tevent/tevent.SlackBuild @@ -24,7 +24,7 @@ cd $(dirname $0) ; CWD=$(pwd) PKGNAM=tevent VERSION=${VERSION:-$(echo $PKGNAM-*.tar.?z | rev | cut -f 3- -d . | cut -f 1 -d - | rev)} -BUILD=${BUILD:-3} +BUILD=${BUILD:-1} # Automatically determine the architecture we're building on: if [ -z "$ARCH" ]; then diff --git a/source/n/php/fetch-php.sh b/source/n/php/fetch-php.sh index 211bc93c6..20c125d26 100755 --- a/source/n/php/fetch-php.sh +++ b/source/n/php/fetch-php.sh @@ -1,2 +1,2 @@ -lftpget http://us.php.net/distributions/php-7.4.28.tar.xz.asc -lftpget http://us.php.net/distributions/php-7.4.28.tar.xz +lftpget http://us.php.net/distributions/php-7.4.29.tar.xz.asc +lftpget http://us.php.net/distributions/php-7.4.29.tar.xz diff --git a/source/n/php/php.SlackBuild b/source/n/php/php.SlackBuild index ef51d81d8..8663af6b4 100755 --- a/source/n/php/php.SlackBuild +++ b/source/n/php/php.SlackBuild @@ -28,7 +28,7 @@ cd $(dirname $0) ; CWD=$(pwd) PKGNAM=php VERSION=${VERSION:-$(echo php-*.tar.xz | rev | cut -f 3- -d . | cut -f 1 -d - | rev)} ALPINE=2.25 -BUILD=${BUILD:-4} +BUILD=${BUILD:-1} # Automatically determine the architecture we're building on: if [ -z "$ARCH" ]; then |
