Computer vulnerabilities of HPE HP-UX
Apache Tomcat: denial of service via SwallowSize
Synthesis of the vulnerability
An attacker can upload an invalid file on Apache Tomcat, to consume a large amount of memory, in order to trigger a denial of service.
Impacted products: Tomcat, Debian, BIG-IP Hardware, TMOS, HP-UX, Oracle Communications, Solaris, RealPresence Collaboration Server, RealPresence Resource Manager, JBoss EAP by Red Hat, Ubuntu.
Severity: 2/4.
Consequences: denial of service on server, denial of service on service, denial of service on client.
Provenance: internet client.
Creation date: 10/04/2015.
Identifiers: bulletinoct2015, c05054964, CERTFR-2015-AVI-204, cpujul2018, CVE-2014-0230, DSA-3530-1, HPSBUX03561, RHSA-2015:1621-01, RHSA-2015:1622-01, RHSA-2015:2659-01, RHSA-2015:2660-01, RHSA-2015:2661-01, RHSA-2016:0595-01, RHSA-2016:0596-01, RHSA-2016:0597-01, RHSA-2016:0599-01, SOL17123, USN-2654-1, USN-2655-1, VIGILANCE-VUL-16570.
Description of the vulnerability
The Apache Tomcat product offers a web service, which can accept the file upload feature.
However, when the tomcat server expects to refuse an upload, it still accepts to read the received file without a memory limit.
An attacker can therefore upload an invalid file on Apache Tomcat, to consume a large amount of memory, in order to trigger a denial of service.

Description of the vulnerability
During the initialization of a TLS session, the client and the server negotiate cryptographic algorithms. The RC4 algorithm can be chosen to encrypt data.
For some weak keys (one over 2^24), the Invariance Weakness can be used to predict the two LSB (Least Significant Bit) of the 100 first bytes encrypted with RC4. The first TLS message is "Finished" (36 bytes), thus an attacker can predict LSBs of 64 bytes.
An attacker can therefore use the Bar Mitzvah Attack on TLS, in order to obtain sensitive information encrypted by RC4.

An attacker can force a read at an invalid address in gd_gif_in.c of libgd or PHP, in order to trigger a denial of service.
Impacted products: Debian, BIG-IP Hardware, TMOS, HP-UX, openSUSE, Solaris, PHP, RHEL, Slackware, SUSE Linux Enterprise Desktop, SLES, Ubuntu, Unix (platform) ~ not comprehensive.
Severity: 2/4.
Consequences: denial of service on server, denial of service on service, denial of service on client.

Description of the vulnerability
The libgd library is used to process images. It is used by PHP.
However, if a GIF image is malformed, the gd_gif_in.c file tries to read a memory area which is not reachable, which triggers a fatal error.
An attacker can therefore force a read at an invalid address in gd_gif_in.c of libgd or PHP, in order to trigger a denial of service.

Description of the vulnerability
The Henry Spencer regex library implements the support of regular expressions. It is used by PHP and MySQL.
The regcomp() function generates a data structure representing a regular expression.
However, if the size of data is greater than the size of the storage array, an overflow occurs in regcomp().
An attacker can therefore generate a buffer overflow in the regcomp() function of Henry Spencer regex, in order to trigger a denial of service, and possibly to execute code.

Description of the vulnerability
The ZIP extension can be installed on PHP, to uncompress ZIP archives. The libzip library uses the same code.
However, if the number of entries in the ZIP archive is too large, a multiplication overflows in the _zip_cdir_new() function, and an allocated memory area is too short.
An attacker can therefore generate an integer overflow in _zip_cdir_new() of PHP or libzip, in order to trigger a denial of service, and possibly to execute code.

Description of the vulnerability
The OpenSSL product processes X.509 certificates.
However, the X509_to_X509_REQ() function does not check if a pointer is NULL, before using it.
An attacker can therefore force a NULL pointer to be dereferenced in X509_to_X509_REQ() of OpenSSL, in order to trigger a denial of service.

Description of the vulnerability
The OpenSSL product implements the Elliptic Curves algorithm.
However, the d2i_ECPrivateKey() function frees a memory area before reusing it.
An attacker can therefore force the usage of a freed memory area in d2i_ECPrivateKey() of OpenSSL, in order to trigger a denial of service, and possibly to execute code.
