Summary
Red Hat Security Advisory: less security update
Notes
Topic
An updated less package that fixes segmentation fault when viewing binary
files is now available.
Details
The less utility is a text file browser that resembles more, but has
extended capabilities.
Victor Ashik discovered a heap based buffer overflow in less, caused by a
patch added to the less package in Red Hat Enterprise Linux 3. An attacker
could construct a carefully crafted file that could cause less to crash or
possibly execute arbitrary code when opened. The Common Vulnerabilities
and Exposures project (cve.mitre.org) has assigned the name CAN-2005-0086
to this issue. Note that this issue only affects the version of less
distributed with Red Hat Enterprise Linux 3.
Red Hat believes that the Exec-Shield technology (enabled by default since
Update 3) will block attempts to remotely exploit this vulnerability on x86
architectures.
All users of the less package should upgrade to this updated package,
which resolves this issue.

Summary
Red Hat Security Advisory: less security update
Notes
Topic
An updated less package that fixes segmentation fault when viewing binary
files is now available.
Details
The less utility is a text file browser that resembles more, but has
extended capabilities.
Victor Ashik discovered a heap based buffer overflow in less, caused by a
patch added to the less package in Red Hat Enterprise Linux 3. An attacker
could construct a carefully crafted file that could cause less to crash or
possibly execute arbitrary code when opened. The Common Vulnerabilities
and Exposures project (cve.mitre.org) has assigned the name CAN-2005-0086
to this issue. Note that this issue only affects the version of less
distributed with Red Hat Enterprise Linux 3.
Red Hat believes that the Exec-Shield technology (enabled by default since
Update 3) will block attempts to remotely exploit this vulnerability on x86
architectures.
All users of the less package should upgrade to this updated package,
which resolves this issue.

Summary
Red Hat Security Advisory: less security update
Notes
Topic
An updated less package that fixes segmentation fault when viewing binary
files is now available.
Details
The less utility is a text file browser that resembles more, but has
extended capabilities.
Victor Ashik discovered a heap based buffer overflow in less, caused by a
patch added to the less package in Red Hat Enterprise Linux 3. An attacker
could construct a carefully crafted file that could cause less to crash or
possibly execute arbitrary code when opened. The Common Vulnerabilities
and Exposures project (cve.mitre.org) has assigned the name CAN-2005-0086
to this issue. Note that this issue only affects the version of less
distributed with Red Hat Enterprise Linux 3.
Red Hat believes that the Exec-Shield technology (enabled by default since
Update 3) will block attempts to remotely exploit this vulnerability on x86
architectures.
All users of the less package should upgrade to this updated package,
which resolves this issue.

"details": "Before applying this update, make sure all previously released errata\nrelevant to your system have been applied.\n\nTo update all RPMs for your particular architecture, run:\n\nrpm -Fvh [filenames]\n\nwhere [filenames] is a list of the RPMs you wish to upgrade. Only those\nRPMs which are currently installed will be updated. Those RPMs which are\nnot installed but included in the list will not be updated. Note that you\ncan also use wildcards (*.rpm) if your current directory *only* contains\nthe\ndesired RPMs.\n\nPlease note that this update is also available via Red Hat Network. Many\npeople find this an easier way to apply updates. To use Red Hat Network,\nlaunch the Red Hat Update Agent with the following command:\n\nup2date\n\nThis will start an interactive process that will result in the appropriate\nRPMs being upgraded on your system.",
