66708303038192047a61eddb05e535eccc4f5020eceeb60349b6a70ac5c0494eUbuntu Security Notice 473-1 - A buffer overflow was discovered in libgd2's font renderer. By tricking an application using libgd2 into rendering a specially crafted string with a JIS encoded font, a remote attacker could read heap memory or crash the application, leading to a denial of service. Xavier Roche discovered that libgd2 did not correctly validate PNG callback results. If an application were tricked into processing a specially crafted PNG image, it would monopolize CPU resources. Since libgd2 is often used in PHP and Perl web applications, this could lead to a remote denial of service.
6abb073db2f4b279f8cc285aabdf42ffb187a69c115712540efffbb55e365bf1Mandriva Linux Security Advisory - Buffer overflow in the gdImageStringFTEx function in gdft.c in the GD Graphics Library 2.0.33 and earlier allows remote attackers to cause a denial of service (application crash) and possibly execute arbitrary code via a crafted string with a JIS encoded font. Tetex 3.x uses an embedded copy of the gd source and may also be affected by this issue. A buffer overflow in the open_sty function for makeindex in Tetex could allow user-assisted remote attackers to overwrite files and possibly execute arbitrary code via a long filename.
09ea777e2263077052ec7d39b6ca87039f3fa15d2bd7cc692d25712c6cdfb3c5Mandriva Linux Security Advisory - PHP 5.2.0 and 4.4 allows local users to bypass safe_mode and open_basedir restrictions via a malicious path and a null byte before a ";" in a session_save_path argument, followed by an allowed path, which causes a parsing inconsistency in which PHP validates the allowed path but sets session.save_path to the malicious path. Buffer overflow in the gdImageStringFTEx function in gdft.c in GD Graphics Library 2.0.33 and earlier allows remote attackers to cause a denial of service (application crash) and possibly execute arbitrary code via a crafted string with a JIS encoded font. PHP uses an embedded copy of GD and may be susceptible to the same issue.
