Moritz Jodeit found that OpenSSL's SSL_get_shared_ciphers() function did not correctly check the size of the buffer it was writing to. As a result, a remote attacker could exploit this to write one NULL byte past the end of the applications's cipher list buffer, which could possibly lead to a denial of service or the execution of arbitrary code (CVE-2007-5135). Updated packages have been patched to prevent these issues. http://www.mandriva.com/security/advisories?name=MDKSA-2007:192 A heap-based buffer overflow was found in MPlayer's AVI handling that could allow a remote attacker to cause a denial of service or possibly execute arbitrary code via a crafted .avi file. Updated packages have been patched to prevent this issue. http://www.mandriva.com/security/advisories?name=MDKSA-2007:191 A heap-based buffer overflow in libsndfile could allow remote attackers to execute arbitrary code via a FLAC file with crafted PCM data which contains a block with a size exceeding that of the previous block. Updated packages have been patched to prevent this issue. http://www.mandriva.com/security/advisories?name=MDKSA-2007:190 A vulnerability was discovered in KDM by Kees Huijgen where under certain circumstances and in particular configurations, KDM could be tricked into allowing users to login without a password. Updated packages have been patched to prevent this issue. http://www.mandriva.com/security/advisories?name=MDKSA-2007:189 A buffer overflow vulnerability was discovered in t1lib due to improper bounds checking. An attacker could send specially crafted input to an application linked against t1lib which could lead to a denial of service or the execution of arbitrary code. Updated packages have been patched to prevent this issue. http://www.mandriva.com/security/advisories?name=MDKSA-2007:188 PostgreSQL 8.1 and probably later and earlier versions, when local trust authentication is enabled and the Database Link library (dblink) is installed, allows remote attackers to access arbitrary accounts and execute arbitrary SQL queries via a dblink host parameter that proxies the connection from 127.0.0.1. (CVE-2007-3278) PostgreSQL 8.1 and probably later and earlier versions, when the PL/pgSQL (plpgsql) language has been created, grants certain plpgsql privileges to the PUBLIC domain, which allows remote attackers to create and execute functions, as demonstrated by functions that perform local brute-force password guessing attacks, which may evade intrusion detection. (CVE-2007-3279) The Database Link library (dblink) in PostgreSQL 8.1 implements functions via CREATE statements that map to arbitrary libraries based on the C programming language, which allows remote authenticated superusers to map and execute a function from any library, as demonstrated by using the system function in libc.so.6 to gain shell access. (CVE-2007-3280) Updated packages fix these issues, by requiring non-superusers who use /contrib/dblink to use only password authentication. http://www.mandriva.com/security/advisories?name=MDKSA-2007:187 Numerous vulnerabilities were discovered in the PHP scripting language that are corrected with this update. An integer overflow in the substr_compare() function allows context-dependent attackers to read sensitive memory via a large value in the length argument. This only affects PHP5 (CVE-2007-1375). A stack-based buffer overflow in the zip:// URI wrapper in PECL ZIP 1.8.3 and earlier allowes remote attackers to execute arbitrary code via a long zip:// URL. This only affects Corporate Server 4.0 (CVE-2007-1399). A CRLF injection vulnerability in the FILTER_VALIDATE_EMAIL filter could allow an attacker to inject arbitrary email headers via a special email address. This only affects Mandriva Linux 2007.1 (CVE-2007-1900). The mcrypt_create_iv() function calls php_rand_r() with an uninitialized seed variable, thus always generating the same initialization vector, which may allow an attacker to decrypt certain data more easily because of the guessable encryption keys (CVE-2007-2727). The soap extension calls php_rand_r() with an uninitialized seec variable, which has unknown impact and attack vectors; an issue similar to that affecting mcrypt_create_iv(). This only affects PHP5 (CVE-2007-2728). The substr_count() function allows attackers to obtain sensitive information via unspecified vectors. This only affects PHP5 (CVE-2007-2748). An infinite loop was found in the gd extension that could be used to cause a denial of service if a script were forced to process certain PNG images from untrusted sources (CVE-2007-2756). An integer overflow flaw was found in the chunk_split() function that ould possibly execute arbitrary code as the apache user if a remote attacker was able to pass arbitrary data to the third argument of chunk_split() (CVE-2007-2872). A flaw in the PHP session cookie handling could allow an attacker to create a cross-site cookie insertion attack if a victim followed an untrusted carefully-crafted URL (CVE-2007-3799). Various integer overflow flaws were discovered in the PHP gd extension that could allow a remote attacker to execute arbitrary code as the apache user (CVE-2007-3996). A flaw in the wordwrap() frunction could result in a denial of ervice if a remote attacker was able to pass arbitrary data to the function (CVE-2007-3998). A flaw in the money_format() function could result in an information leak or denial of service if a remote attacker was able to pass arbitrary data to this function; this situation would be unlikely however (CVE-2007-4658). A bug in the PHP session cookie handling could allow an attacker to stop a victim from viewing a vulnerable website if the victim first visited a malicious website under the control of the attacker who was able to use that page to set a cookie for the vulnerable website (CVE-2007-4670). Updated packages have been patched to prevent these issues. In addition, PECL ZIP version 1.8.10 is being provided for Corporate Server 4.0. http://www.mandriva.com/security/advisories?name=MDKSA-2007:186 An integer overflow in the TIFF parser in OpenOffice.org prior to version 2.3 allows remote attackers to execute arbitrary code via a TIFF file with crafted values which triggers the allocation of an incorrect amount of memory which results in a heap-based buffer overflow. Updated packages have been patched to prevent this issue. http://www.mandriva.com/security/advisories?name=MDKSA-2007:185 The Avahi daemon in 0.6.20 and previous allows attackers to cause a denial of service via empty TXT data over D-Bus, which triggers an assert error. Updated packages have been patched to prevent this issue. http://www.mandriva.com/security/advisories?name=MDKSA-2007:184 A vulnerability in Cacti 0.8.6i and earlier versions allows remote authenticated users to cause a denial of service (CPU consumption) via large values of the graph_start, graph_end, graph_height, or graph_width parameters. Updated packages have been patched to prevent this issue.
