libXfont2: BitmapScaleBitmaps Integer Overflow Heap Buffer Overflow

A flaw was found in libXfont2. In the BitmapScaleBitmaps function, an integer overflow can occur when calculating the memory needed for font glyphs. This overflow leads to a heap buffer overflow, where a smaller-than-required memory buffer is allocated. A local attacker can exploit this by loadin...

libXfont2: PCF Font Parsing Heap Buffer Overflow

A flaw was found in libXfont2. A specially crafted PCF Portable Compiled Format font file, when processed by libXfont2, can lead to a buffer overflow. This occurs because the font parsing process does not properly validate the size of a bitmap buffer against the glyph metrics provided in the...

libXfont2: computeProps Property Buffer Heap Buffer Overflow

A heap buffer overflow due to missing size checking in the property buffer when parsing PCF files in libXfont2 ComputeScaledProperties before libXfont2 before 2.0.8 could be used by attackers using authenticated X clients to execute code within the X server...

SUSE CVE-2007-1352

Integer overflow in the FontFileInitTable function in X.Org libXfont before 20070403 allows remote authenticated users to execute arbitrary code via a long first line in the fonts.dir file, which results in a heap overflow...

SUSE CVE-2017-13720

In the PatternMatch function in fontfile/fontdir.c in libXfont through 1.5.2 and 2.x before 2.0.2, an attacker with access to an X connection can cause a buffer over-read during pattern matching of fonts, leading to information disclosure or a crash denial of service. This occurs because '\0'...

libxfont Denial of Service Vulnerability

libXfont is an X font processing library for servers and utilities from the X.Org Foundation. A denial of service vulnerability exists in the 'PatternMatch' function of the fontfile/fontdir.c file in libXfont versions 1.5.2 and earlier and version 2.x before 2.0.2. An attacker can exploit this...

DEBIAN-CVE-2017-13720

In the PatternMatch function in fontfile/fontdir.c in libXfont through 1.5.2 and 2.x before 2.0.2, an attacker with access to an X connection can cause a buffer over-read during pattern matching of fonts, leading to information disclosure or a crash denial of service. This occurs because '\0'...

DEBIAN-CVE-2015-1802

The bdfReadProperties function in bitmap/bdfread.c in X.Org libXfont before 1.4.9 and 1.5.x before 1.5.1 allows remote authenticated users to cause a denial of service out-of-bounds write and crash or possibly execute arbitrary code via a 1 negative or 2 large property count in a BDF font file...
