An issue in the imlibfreeimageanddecache function of imlib2 v1.9.1 allows attackers to cause a heap buffer overflow via parsing a crafted image.

An issue in the imlibloadimagewitherrorreturn function of imlib2 v1.9.1 allows attackers to cause a heap buffer overflow via parsing a crafted image.

imlib2 v1.9.1 was discovered to mishandle memory allocation in the function initimlibfonts().

enlightenmentsys in Enlightenment before 0.25.4 allows local users to gain privileges because it is setuid root, and the system library function mishandles pathnames that begin with a /dev/.. substring.

modules/loaders/loaderico.c in imlib2 1.6.0 has an integer overflow (with resultant invalid memory allocations and out-of-bounds reads) via an icon with many colors in its color map.

Terminology before 1.3.1 allows Remote Code Execution because popmedia is mishandled, as demonstrated by an unsafe "cat README.md" command when \e}pn is used. A popmedia control sequence can allow the malicious execution of executable file formats registered in the X desktop share MIME types (/usr/share/applications). The control sequence defers unknown file types to the handleunknownmedia() function, which executes xdg-open against the filename specified in the sequence. The use of xdg-open for all unknown file types allows executable file formats with a registered shared MIME type to be executed. An attacker can achieve remote code execution by introducing an executable file and a plain text file containing the control sequence through a fake software project (e.g., in Git or a tarball). When the control sequence is rendered (such as with cat), the executable file will be run.

Enlightenment before 0.17.6 might allow local users to gain privileges via vectors involving the gdb method.

Terminology 0.7.0 allows remote attackers to execute arbitrary commands via escape sequences that modify the window title and then are written to the terminal, a similar issue to CVE-2003-0063.

imlib2 before 1.4.7 allows remote attackers to cause a denial of service (divide-by-zero error and application crash) via a crafted PNM file.

imlib2 before 1.4.7 allows remote attackers to cause a denial of service (segmentation fault) via a crafted GIF file.

imlib2 before 1.4.7 allows remote attackers to cause a denial of service (segmentation fault) via a GIF image without a colormap.

Integer overflow in imlib2 before 1.4.9 on 32-bit platforms allows remote attackers to execute arbitrary code via large dimensions in an image, which triggers an out-of-bounds heap memory write operation.

An integer overflow vulnerability was found in imlib2.

Off-by-one error in the imlibMergeUpdate function in lib/updates.c in imlib2 before 1.4.9 allows remote attackers to cause a denial of service (out-of-bounds read and application crash) via crafted coordinates.

The GIF loader in imlib2 before 1.4.9 allows remote attackers to cause a denial of service (application crash) or obtain sensitive information via a crafted image, which triggers an out-of-bounds read.

These aren't security flaws, precisely, due to some of the other defaults that Fedora has that other distros/vendors may not, but upstream recently did some hardening to the defaults they provide (and we don't change) based on Martin Carpenter's report.

esys - address security concerns with environment and gdb

1. clear out environment as best is possible before executing anything. especially PATH and IFS are set to minimal base defaults. also use clearenv() if available and unsetenv()

2. remove gdb method as it's just too dangerous. run it as normal as the user and if the kernel / distro dny that - then sorry. too bad.

An unspecified setuid root helper in Enlightenment before 0.17.6 allows local users to gain privileges by leveraging failure to properly sanitize the environment.

imlib2 before 1.4.9 allows remote attackers to cause a denial of service (divide-by-zero error and application crash) by drawing a 2x1 ellipse.

Multiple heap-based buffer overflows in imlib2 1.4.3 allow context-dependent attackers to execute arbitrary code via a crafted (1) ARGB, (2) XPM, or (3) BMP file, related to the IMAGEDIMENSIONSOK macro in lib/image.h.

imlib2 before 1.4.2 allows context-dependent attackers to have an unspecified impact via a crafted (1) ARGB, (2) BMP, (3) JPEG, (4) LBM, (5) PNM, (6) TGA, or (7) XPM file, related to "several heap and stack based buffer overflows - partly due to integer overflows."

The load function in the XPM loader for imlib2 1.4.2, and possibly other versions, allows attackers to cause a denial of service (crash) and possibly execute arbitrary code via a crafted XPM file that triggers a "pointer arithmetic error" and a heap-based buffer overflow, a different vulnerability than CVE-2008-2426.
