From: [EMAIL PROTECTED] Operating system: Linux 6.2 and 7.2 PHP version: 4.1.1 PHP Bug Type: Date/time related Bug description: date("r") returns wrong timezone offset, can cause crash
I have tested both PHP 4.1.1 and PHP 4.05 and the following occurs for both. The date('r') call returns the wrong timezone offset (in my case "+101800") which causes a buffer overflow in datetime.c The date("Z") call correctly returns the timezone offset number of seconds (630 in my case). The undocumented (in the PHP manual anyway) option to strftime('%z') returns the correct value of +1030. The timezone abbreviation ("CST" in my case) is correctly returned with both the strftime("%Z") and date("T") calls. This will often cause the process to seg fault and die, althought on more complex pages, this becomes quite consistant. With the PHP compile option '--enable-debug', the following is reported in the Apache error log: --------------------------------------- zend_execute_API.c(274) : Block 0x0813EDA0 status: zend_variables.c(44) : Actual location (location was relayed) Beginning: OK (allocated on datetime.c:331, 32 bytes) End: Overflown (magic=0x2A8F0030 instead of 0x2A8FCC84) 2 byte(s) overflown --------------------------------------- For PHP 4.1.1 the configure line is: ./configure --with-mysql=/usr/local/mysql --enable-track-vars --with-apxs=/usr/local/apache/bin/apxs --with-config-file-path=/usr/local/apache/conf --enable-bcmath --with-zlib --with-xml --with-gettext --with-imap=../imap --with-mcrypt --with-ldap=/usr/local --enable-ftp --without-gd --enable-debug (Will be used for Horde's IMP webmail system) -- Edit bug report at http://bugs.php.net/?id=15362&edit=1 -- Fixed in CVS: http://bugs.php.net/fix.php?id=15362&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=15362&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=15362&r=needtrace Try newer version: http://bugs.php.net/fix.php?id=15362&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=15362&r=support Expected behavior: http://bugs.php.net/fix.php?id=15362&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=15362&r=notenoughinfo -- PHP Development Mailing List <http://www.php.net/> To unsubscribe, visit: http://www.php.net/unsub.php
